UI/UX Consulting01
Unlock better product decisions with our strategic UI/UX consulting services. We help you clarify your vision, align stakeholders, and translate business goals into user-centered experiences. Our consultants audit your current journeys, identify gaps, and create a practical roadmap to improve usability, engagement, and conversions.
UX Research02
Make design decisions backed by real user data. We conduct in-depth UX research—interviews, surveys, usability tests, and behavioral analysis—to uncover how your customers think, feel, and act. These insights shape smarter product strategies, reduce guesswork, and ensure your UI/UX design truly serves user needs.
Usability Testing03
Ensure your website or app is easy, intuitive, and frustration-free. Our usability testing services reveal where users struggle, why they drop off, and what stops them from converting. We turn findings into clear recommendations that improve task completion rates, satisfaction, and overall product performance.
Wireframing & Prototyping04
Bring ideas to life before writing a single line of code. We create detailed wireframes and interactive prototypes that map user flows, content hierarchy, and interactions. This rapid iteration process helps you validate concepts early, align teams, and move into UI design with confidence.
UX Audit05
Optimize your existing product with a data-driven UX audit. We review user journeys, information architecture, interaction patterns, and accessibility to pinpoint friction and missed opportunities. You receive a prioritized action plan to enhance user experience, increase retention, and improve conversion rates.
Design System Audit06
Keep your digital experience consistent at scale. Our design system audit evaluates components, styles, and usage rules across your product suite. We refine tokens, patterns, and documentation so your teams can ship interfaces faster while maintaining a cohesive brand and unified UX.
UI/UX Design07
Get end-to-end UI/UX design that blends aesthetics, usability, and business impact. We craft responsive, accessible interfaces for web and mobile that support clear user journeys, reduce cognitive load, and drive measurable results—whether that’s more sign-ups, more sales, or deeper engagement.
Our UI Design Process
We design interfaces around real users and real business goals. Our UI/UX team works closely with you to understand your product vision, target audience, and success metrics. From there, we design clean, conversion-focused interfaces that feel intuitive on every device, following a clear, repeatable process so nothing is missed.
01. Understand & Refine the Design Brief
We start by reviewing your design brief in depth. If anything is unclear, we’ll jump on a call or ask targeted questions to clarify scope, priorities, and constraints. This alignment step removes guesswork, avoids rework later, and ensures we’re solving the right problems from day one.
02. Plan & Estimate the Design Work
Next, we break down the UI design work into milestones and estimate timelines for each stage. For larger or multi-platform projects, we’ll share a simple project plan with key deliverables and checkpoints. This keeps everyone aligned on expectations, deadlines, and dependencies throughout the UI/UX design process.
Wireframing & Layout Validation
We then create high-fidelity wireframes to define structure, hierarchy, and user flows. These wireframes serve as a blueprint for your product’s interface, letting you approve layout and functionality before visual design starts. We share and discuss them using tools like Figma/InVision and your preferred project management platforms for fast, focused feedback.
Visual UI Design & Interaction Details
Once wireframes are approved, we move into full UI design. We explore visual directions that match your brand and optimize for usability, accessibility, and conversion. You’ll see polished interface designs—often with a few variations—tailored to your business objectives and your users’ needs, covering key screens, states, and interactions.
Final Delivery & Design Handover
After you sign off on the final UI, we prepare a complete design handover. This includes organized source files, style guides, component libraries, and annotations that explain how the interface should behave in different states and breakpoints. Your development team gets everything they need to implement the design accurately and maintain consistency as your product grows.

What Our Clients Say About Working With Us
Our clients trust us to turn complex ideas into simple, high-performing digital experiences—and we don’t take that trust lightly. From startups to global brands, teams choose us for our reliable delivery, clear communication, and results they can measure in revenue, efficiency, and growth. Here’s what they have to say about partnering with us.
“We launched a clean Shopify migration in 5 weeks no downtime and saw +27% revenue over BFCM.”
Our legacy store crashed under promo traffic. Mondaysys planned a phased cutover, live-synced inventory, and rehearsed rollback paths. Launch day felt boring in the best way and BFCM finally scaled without firefighting.
“The LLM chatbot deflects 38% of tickets and cut first response time to under a minute.”
Support was drowning in “Where’s my order?” tickets. Mondaysys trained an LLM on our policies, added guardrails, and integrated with Helpdesk for order status and refunds. Agents now handle the hard stuff; the bot handles the rest, fast.
“Their QA discipline drove defect escape below 0.8% releases are finally boring (in the best way).”
We shipped features but also bugs. Mondaysys built a risk-based test plan, added Playwright automation, a11y checks, and data-layer contracts. A pre-release gate stopped regressions cold users noticed stability, not slips.
“Cloud cost down 35%, deployments moved from weekly to daily, Mondaysys modernized our DevOps fast.”
Infra spend climbed while deploys lagged. Mondaysys right-sized clusters, set autoscaling, codified everything in IaC, and rebuilt CI/CD with canary releases. Teams ship daily now and finance finally smiles at the bill.
“The mobile app relaunch cut crash rate by 70% and bumped ratings from 4.2 to 4.8.”
Crashes spiked during peak hours. Mondaysys instrumented the app, traced memory leaks, added offline caching and progressive sync, and simplified onboarding. The app feels instant; reviews turned into referrals.
“Attribution finally makes sense, CAC down 15% after Mondaysys fixed our GA4 and data layers.”
Our channels argued over credit; budgets were blind. Mondaysys audited tags, moved us to server-side, deduped events, and standardized UTMs. Now we fund what works—and cut what doesn’t.
“Mondaysys tripled our A/B test velocity and delivered a 22% conversion lift in six weeks.”
Our tests were stuck behind dev queues and a messy data layer. Mondaysys set up a reusable experiment library, fixed analytics contracts, and created a QA checklist so releases didn’t stall. We went from 2 to 6+ tests/month and finally learned what moved revenue.
“Their MondayPOS ERP rollout gave us 98.5% inventory accuracy and cut checkout time by 40%, game changer.”
Shrink and price disputes were draining margins. Mondaysys ran a full stock audit, mapped barcodes to variants, and enforced pricing rules at POS. Cashiers stopped overriding prices; managers got real-time stock lines got shorter, errors vanished.
“Personalized recommendations from Mondaysys boosted AOV by 18% and repeat purchases by 12%.”
Customers couldn’t find the right shades, so carts stayed small. Mondaysys cleaned our catalog, trained an AI ranker on purchase + browse signals, and launched bundles for cold-start users. Discovery felt human, baskets grew overnight.
Frequently Asked Questions
What is A/B testing (in one sentence)?
A controlled experiment that splits traffic between two (or more) versions to measure which one improves a target metric (e.g., conversion rate, revenue per visitor).
Why is A/B testing important for my website?
It turns guesses into measured wins, reduces redesign risk, and compounds revenue by shipping only what proves to lift your KPIs.
How long should a test run?
Often 1–2 weeks (sometimes longer) to cover behavior cycles and reach a trustworthy sample; exact duration depends on traffic, baseline conversion, and expected lift.
Will A/B testing hurt my SEO?
No—when done correctly (no cloaking, use 302s for temporary redirects, use rel=canonical, don’t run tests for excessive durations). This is straight from Google’s guidance.
Can I still use Google Optimize?
No, Google Optimize sunset on September 30, 2023. We migrate clients to platforms like Optimizely, VWO, Convert, AB Tasty, LaunchDarkly, or Statsig.
What if my site has low traffic can I still test?
Yes: run higher-impact changes, use site-wide tests, combine micro-conversions, or use methods like sequential analysis and Bayesian approaches; supplement with research (surveys, recordings, heuristic reviews).
What does your “A/B Test Development” include?
End-to-end build: spec → design → engineering (platform-agnostic) → analytics tagging → cross-device QA → launch → monitor → analyze → ship winner → document learning.
Do you handle QA and analytics?
Yes. We pressure-test variants across devices/browsers, validate events (GA4/Segment/Adobe), and share QA checklists and test readouts.
Can Mondaysys work with our existing team?
Absolutely. We plug in as an experimentation pod or augment design/engineering/analytics to increase velocity without disrupting your process.
What tools do you support?
Optimizely, VWO, Convert, AB Tasty, Dynamic Yield, Adobe Target, Kameleoon, LaunchDarkly/Statsig (feature flags), and custom frameworks. We integrate with GA4, Segment, Adobe, Looker, and your data warehouse.
How do I get started with Mondaysys?
Book a quick discovery. We’ll run a rapid audit (traffic, analytics, tech stack), propose a 90-day experiment plan, and start with a pilot test.
How do I hire a great Shopify developer (fast checklist)?
Look for: (1) theme & Liquid mastery, app/extensibility, and Shopify CLI; (2) performance (Lighthouse, LCP/CLS), accessibility, and SEO basics; (3) experience with Shopify Plus, checkout extensibility, Scripts/Functions; (4) analytics/GA4 events; (5) clear comms, clean Git habits, and QA discipline. Ask for code samples and shipped storefronts.
Can you A/B test on Shopify?
Yes, theme variants, templates, sections, PDP, cart, and (with Plus/eligible setups) certain checkout experiences via approved methods or platform tools; Shopify publishes guidance for merchant-assigned testing in specific components.
Do you build custom Shopify features too?
Yes. We handle theme builds, app integrations, performance tuning, internationalization, subscriptions, and CRO-driven UX updates.
How much do your services cost?
We scope to your goals and traffic. Typical models: (1) Experimentation Pod (monthly retainer) for steady velocity; (2) Fixed-fee pilot (audit + 1–2 launches); (3) Project-based Shopify builds. Request a tailored plan after a 30-min discovery.
Do you support Bayesian or frequentist analysis?
Both, we choose based on your data volume, decision cadence, and stakeholder preference, and we document assumptions either way.
What if a test is inconclusive?
We capture the learning, refine the hypothesis, and iterate (bigger change, better targeting, or different step in the funnel).
How many conversions do I need to trust a result?
There’s no single magic number it depends on baseline rate and desired lift. We estimate sample size up front and won’t call a winner before confidence thresholds are met.
How quickly can you launch the first test?
Commonly 1–2 weeks after access and audit (faster if your tagging and environments are ready).
Will experiments slow down my site?
Our builds are performance-first (async loads, minimal blocking, code splitting). We monitor Core Web Vitals on variant and control.
Do you migrate teams off Google Optimize?
Yes, assessment, tool selection, event parity, QA, and phased cutover from Optimize to an enterprise-grade platform.
Can you coordinate with our SEO team during tests?
Yes, we follow Google’s testing guidance (302s, rel=canonical, no cloaking) and share test scopes/URLs so SEO stays healthy.
