Software Engineer · Product Builder
I'm Muhammad Hassan — a software engineer with 5+ years owning delivery on React, Next.js, and React Native products. I've shipped platforms at $1M+ monthly volume. I use agentic coding workflows daily and stay accountable for what lands in production.
01 / About
How I think about ownership, what I've shipped, and the stack behind production releases.
10+
Products Shipped
5+
Years Experience
I build and own web and mobile products — not ticket queues. 5+ years on React, Next.js, and React Native cut redundant code by 40% on teams I led.
I've shipped platforms at $1M+ monthly volume for global users. My GitHub and case studies here show the trade-offs, not just the stack logos. Judgment and release discipline matter more than typing speed now.
01
SSR, SEO, and component architecture for web products teams can extend.
02
Cross-platform mobile apps — offline flows, push, and App Store releases.
03
Lazy loading, code splitting, and runtime tuning on real traffic.
04
Cursor, Claude Code, and spec-driven workflows — with human review before merge.
02 / Experience
Software engineering roles across product teams — from idea through App Store and Play Store release.
Leading end-to-end development of enterprise-grade mobile applications using React Native and Expo, with full ownership of architecture, technical decisions, and delivery. Architecting scalable, offline-capable mobile solutions with TypeScript, Zustand, and React Query Integrating real-time features including WebSockets and push notifications Working across REST APIs and GraphQL with Firebase/Supabase backend services Establishing mobile development best practices, CI/CD pipelines, and App Store / Play Store deployment workflows Collaborating cross-functionally with product, design, and backend teams to ship high-performance, secure applications
React Native / Expo / TypeScript / +8
Leading development of scalable web and mobile applications using React and React Native. Working remotely with cross-functional teams, focusing on performance, clean architecture, and modern UI/UX.
React / React Native / Next.js / +6
Built and maintained cross-platform mobile applications for Android and iOS using React Native. Integrated REST APIs, managed state with Redux, and collaborated in Agile teams with regular code reviews.
React / React Native / Next.js / +7
Developed and maintained web and mobile applications that enhanced digital learning experiences. Led application development, collaborated with cross-functional teams, and ensured high code quality through reviews.
React / React Native / Next.js / +9
Worked on web and mobile applications using React, React Native, and Next.js. Focused on building responsive UIs, managing state efficiently, and integrating Firebase services for backend functionality.

03 / Selected Work
Case studies from shipped products — problem, what I owned, trade-offs, and production outcomes.
01 / Mobile Application
React Native Matrix case study — E2EE messaging solo-built in 4 weeks. Rust SDK via UniFFI, zero backend, LiveKit calls.
02 / Educational Ecosystem
GRE prep platform I built — test-like practice flows, Stripe and PayPal payments, and student management at scale.
03 / Mobile & Web
IP-protected LMS I built end to end — synced audio-text reading, screen-capture prevention, App Store release.
Want the full picture? Every case study includes what I owned and what shipped.
04 / Writing
Agentic coding, system design, and mobile delivery — written from products I ship, not theory threads.
Agentic coding is when an AI agent plans, edits files, runs tests, and retries in a loop while you supervise instead of typing. Here is how the agent loop works, when to use it, and how to stay in control.
AI made building software faster. It did not make problem-solving cheaper. Implementation is a tactic; product thinking, distribution, and maintenance decide whether anyone actually uses what you ship.
You do not need to start over. If you already ship production software, AI engineering is mostly learning how to build reliable systems around models — LLM APIs, RAG, agents, and evaluation — on top of skills you already have.
