What I ship
I take projects end-to-end. Pick a lane below, or describe what you need. I’ll tell you honestly whether it’s a fit.
Complex web & mobile platforms
capability-rocket
01 / 05
Dashboards, portals, and cross-platform mobile apps with real auth and real data behind them. Built around how your team actually works, from an empty repo to a deployed product.
Cloud & backend architecture
capability-plug
02 / 05
The senior layer: database design, secure APIs, and deploy workflows that keep working once real traffic and edge cases show up.
Pragmatic AI integrations
capability-sparkles
03 / 05
AI features grounded in your own data: answering questions, summarising content, or automating a real workflow, built to hold up in production.
Make a slow product fast
capability-gauge
04 / 05
Send me a sluggish site and I find the bottleneck and ship the fix. A recent refactor cut the bundle 30% and load times 24%.
Automated deploys & CI/CD
capability-ship
05 / 05
Stop deploying by hand. I set up automated testing and zero-downtime pipelines so every change ships safely and predictably.

Nasim rebuilt our quiz and learning platform from the architecture up. Bundle size dropped 30%, pages load 24% faster, and the payment-gated access and role permissions just work. He operates like a senior in-house hire, not a contractor.
Yusuf Al-Harbi, Founder & CEO, AzoozGAT LLC
On our payment-processing paths he made request handling idempotent and cut redundant database calls without breaking a thing. He's careful with the fintech edge cases that actually matter, clear in code review, and reliable across time zones.
Wei-Lin Tan, Senior Backend Engineer, WEX (APAC)
He took Budee from a Figma file to a working budget app on a tight timeline. Pragmatic scope calls, clean TypeScript, and he flagged the risky parts before they turned into problems instead of after.
Marcus Reilly, Founder, Budee.io
Two projects, both shipped exactly to scope and then some - Google and Meta Ads wired in cleanly and measurable from day one. One of the most dependable engineers we've hired on Upwork.
Priya Nair, Product Manager, B2B SaaS startup
xenvsync replaced our half-broken dotenv sharing overnight - end-to-end encrypted, no cloud in the trust chain, and an audit log that actually reads clearly. Rare to find open source this thoughtfully built.
Tomas Novak, Platform Engineer, Series-B fintech
We needed a recovery app that stayed private and worked offline. Nasim delivered crisis help at a tap and role-based support across recovery types - and he genuinely cared about the people on the other side of the screen.
Sarah Whitman, Program Director, Recovery non-profit

How we work together
One route from first call to handoff. You always know which stage we’re in and what lands next.
We find the actual bottleneck before touching code. You get a written problem statement you can disagree with.
Data model, API surface, and deploy topology mapped and approved. Every expensive decision happens here, on paper.
A live staging link every week. You steer early instead of reading a status report at the end.
Edge cases, retries, idempotency, and load. The unglamorous week that decides whether it survives real traffic.
Zero-downtime pipeline, monitoring wired, and documentation your team can act on whether I stay or not.
Two paths, same inbox
Send a two-line overview of what you’re building or hiring for, and I’ll reply with an honest take on fit, scope, and timeline. I usually reply within 24 hours.
