Murray WilliamsMurray
Senior React Developer / UX Designer
I'm a JavaScript/TypeScript engineer specialising in React, React Native, and Next.js, with a strong focus on great UX. At SuperGroup, I've been shipping across web and mobile interfaces. I like leading delivery, keeping team momentum high, and using smart AI workflows to clear out tedious tasks.
Senior React, React Native, and TypeScript engineer based in Cape Town. At SuperGroup, I ship web and mobile UI while maintaining an existing Angular codebase. Outside of that, I run Integrio, a family business building ultra-fast Astro sites on Cloudflare that integrate with local and international property management systems, pushing for 100/100 PageSpeed scores across all metrics. I am focused on full-time remote roles where I do my best work, though I am open to coming into a Cape Town office occasionally for team alignment, planning sessions, or key milestones. I am simply looking to avoid a mandatory 3 to 4 day weekly commute.
Remote-first with ad-hoc local flexibility. Cape Town, South Africa · SAST / GMT+2 (great UK overlap).

I am focused on full-time remote roles where I do my best work, though I am open to coming into a Cape Town office occasionally for team alignment, planning sessions, or key milestones. I am simply looking to avoid a mandatory 3 to 4 day weekly commute.
I step in as a senior engineer who bridges Figma designs and clean production code. I take loose product ideas, break them down into manageable tasks, and keep sprint delivery moving. Frontend and mobile are my primary focus, but building out Integrio gives me strong practical experience with light full-stack tech like Hono, Supabase, and edge deployments.
I review code, pair with other devs, and keep the codebase easy for the next person to pick up. For me, it is about actual team ownership and building good software, not just grabbing a ticket and trying to get it off my plate as fast as possible.
I use AI workflows to speed up repetitive tasks and clear out boilerplate, but I firmly believe AI is at its best with a human in the loop. Having a senior dev engaged from the initial tech spec all the way to final delivery is invaluable, and AI simply acts as a multiplier on top of that experience.
“Murray is extremely innovative, he has a great foresight in determining the best solution for the task/challenge at hand and the implications a decision will have on future aspects of the specific workflows. He has strong technical and people skills with an extremely calm disposition that is authoritative in its own right.”
Adding AI tools is easy, but getting real team velocity out of them takes structure. I use AI to speed up research, setup, and testing, while keeping system architecture, UX, and code quality firmly under human control.
Speed
Shorter cycles
Control
Human led
Trust
Checked output
01
Frame
Walk the discovery path early to map risks, uncover edge cases, and define clear success criteria before writing any code.
02
Split
Divide complex features into smaller, manageable pieces, like UI components, API contracts, and data models, so work moves forward smoothly without bottlenecks.
03
Amplify
Let AI agents handle boilerplate, initial drafts, and repetitive implementation while I focus on system architecture, business logic, and UI polish.
04
Verify
Combine strict type safety, review loops, edge-case checks, and hands-on QA to ensure speed doesn't turn into tech debt.
05
Compound
Turn effective prompts, checklists, and workflow patterns into reusable team assets so every sprint gets faster.
Skill workflows
I don't just chat with LLMs in a browser tab. I use structured skill workflows inspired by setups like Matt Pocock's to run a clean idea-to-ship pipeline. Click a skill on the left to see a simulated trace of how I use agents during discovery, implementation, and code review.

Challenge
High-traffic web and gaming products need fast, responsive interfaces that evolve quickly without breaking core customer journeys or slowing down release cycles.
Action
Own React, React Native, and TypeScript frontend delivery. Translate Figma designs into clean production code, maintain active Angular legacy applications, and collaborate with backend and QA teams to ship reliable features.
Impact
Keeps web and mobile experiences stable and maintainable while maintaining steady sprint velocity in a fast-paced product environment.
Challenge
Accommodation operators need high-speed, custom booking sites that keep guests on-brand instead of redirecting them into generic third-party checkouts.
Action
Build high-performance Astro sites on Cloudflare infrastructure. Integrate Hono APIs, Supabase (Postgres), and external property management systems to handle real-time availability and fast booking flows.
Impact
Ships live platforms across South Africa, the UK, Scotland, and Canada that consistently hit near 100/100 PageSpeed scores across performance and accessibility metrics.
Challenge
Client teams across the UK, SA, and Canada need senior frontend execution and UX direction to bridge the gap between design concepts and production-ready code.
Action
Build frontend applications using Next.js and React, connect custom CRM pipelines, configure Cloudflare and Google Cloud services, and design conversion-focused interfaces in Figma.
Impact
Keeps client projects moving forward by delivering clean code, reliable cloud setups, and clear design direction for teams without a dedicated internal lead.
Challenge
A Ruby on Rails property management system required cleaner user flows, improved booking usability, and reliable calendar sync across external booking channels.
Action
Designed and built reusable UI components, revamped the core enquiry flow, and parsed iCal feeds to sync third-party bookings with internal calendars. Wrote backend RSpec tests for features shipped.
Impact
Improved booking conversion, reduced availability sync mismatches between Inn Style and external channels, and worked directly with leadership to ship core product updates.
