“Programs must be written for people to read & only incidentally for machines to execute.”— Harold Abelson
A pragmatic, modern toolkit spanning the full stack — chosen for reliability, performance & developer experience.
Every project ships on a foundation of battle-tested frameworks, languages & platforms — the same tools trusted by teams building at scale.
A few non-negotiables that shape each technical decision, from the first sketch to production support.
Software should be dependable under real load. I optimize for correctness and resilience before cleverness.
The best code is the code the next engineer understands instantly. I write for humans first.
Speed is respect for the user's time. I treat performance budgets as first-class requirements.
From the database to the pixel, I take end-to-end ownership of what I ship.
Full-stack engineering services for teams and founders who need one engineer accountable for the whole build.
End-to-end web apps built to scale.
I design and ship complete web applications — from database and API to a fast, accessible React and Next.js interface. One engineer accountable for the whole stack, so nothing falls between the cracks.
Fast, conversion-focused online stores.
Custom e-commerce experiences that load fast, rank well & convert — from headless storefronts and secure checkout to product catalogs, carts & payment integrations built to handle real traffic.
Turn your manual business into an online product.
I turn offline, spreadsheet-and-paper operations into a real online product — mapping how your business runs today, then building the customer-facing app, internal workflows & data migration that replace the manual steps. You move from ad-hoc processes to a system you can measure, scale & sell.
A simple, visible cadence that turns an idea into reliable software without losing momentum or context.
We start with your goals, constraints & timeline. I map the problem, clarify requirements & turn ambiguity into a clear, prioritized plan.
STEP 01I design the data model, API surface & system architecture up front — choosing the right tools so the product stays fast and maintainable as it grows.
STEP 02You get working software early and often, with tested, reviewed code and regular check-ins so we can adjust direction based on real feedback.
STEP 03I handle deployment, monitoring & performance, then stay available for iteration and maintenance so the launch is a beginning, not a handoff.
STEP 04A few builds I'm proud of — spanning full-stack apps, backend systems & open-source work.
Smart parking management platform connecting drivers with parking-space providers.
Building and scaling products across healthtech, e-commerce & open source.

Feedback from managers, peers I've built alongside.
“I had the pleasure of working closely with Zahid in our team, and I can confidently say that he is an exceptional engineer with a remarkable passion for his work. Zahid's sharp intellect and keen understanding of business needs consistently translate into high-quality, well-crafted code. His dedication to staying at the forefront of technological advancements is truly inspiring. Zahid's ability to seamlessly integrate innovative solutions into our projects not only improves our deliverables but also pushes our team to new heights. Zahid is not just a talented engineer; he is a visionary who sees the bigger picture and drives his projects with precision and enthusiasm. I am certain that his career will continue to soar, and he will achieve great success in the future.”
“I've worked next to Zahid for over four years now, and the thing that's stood out the whole time is how he makes hard problems look routine. He rebuilt Arogga's internal admin platform basically from scratch — 80+ modules, everything from inventory to accounting — and somehow kept it all coherent instead of letting it spiral, which most people wouldn't manage. What I appreciate more, though, is how he works day to day. He'll stop what he's doing to help debug something that isn't even his code, and he actually explains the "why" instead of just fixing it and moving on. Four years is long enough to see someone's rough edges, and honestly he's held up well — still cares about doing it right over doing it fast. If you get the chance to work with him, take it.”
“I had the pleasure of working with him at Arogga Ltd, and I am thrilled to provide a recommendation for them. He is an exceptional frontend developer with deep expertise in React and a profound understanding of modern web technologies. During our time together, he consistently demonstrated a high level of skill and creativity in developing web applications. Their ability to translate complex requirements into seamless, efficient code was truly impressive. They are not only proficient in React but also excel in utilising HTML, CSS, and JavaScript to create robust and scalable solutions. I highly recommend him for any frontend development role. They will undoubtedly be a tremendous asset to any team and contribute significantly to the success of any project they undertake.”
Thoughts on engineering, architecture & building for the web.
The WebSocket demo works in five minutes. The problems start after: reconnection, authenticating a long-lived connection, events missed while a client was away & what happens when you run more than one server. Notes from building event-driven real-time systems for real users.
Caching is sold as a performance win and paid for in staleness bugs. A look at the actual decision: which reads are worth caching, how to invalidate without lying to users & the cases where adding a cache creates more problems than the latency it removes.
At a handful of screens, copy-paste is fine. At eighty, it's the thing that kills you. A look at the resource abstraction that held a large admin platform together — and the escape hatches that kept it from becoming a straitjacket.
The working relationship is as important as the code: clear ownership, steady communication & a focus on outcomes.
From architecture and interface work to deployment and iteration.
Regular check-ins, working software early & direct communication.
