Lead software engineer specializing in everything JavaScript, 8+ years in.
I work across web development and web automation. On the development side that means production APIs and full-stack products in Node.js, TypeScript, Fastify and React/Next.js. On the automation side, scraping, third-party integrations and the data pipelines that keep other people's products supplied. More recently I have been working with AI tooling, including RAG, function calling and structured outputs.
Based in Islamabad, Pakistan. I work with teams across UK, US and Gulf timezones, and write practical tutorials and code snippets at javascripthacker.com.
Open to contract and part-time engagements of roughly 20–30 hours per week. Strongest fit:
- Building and maintaining external data pipelines, including collection, normalization, deduplication, retries, monitoring and alerting.
- AI integration work: RAG, tool calling and agentic workflows with schema-validated output and deterministic fallbacks.
- Taking over pipelines and integrations that have become unreliable and making them dependable again.

| Repository | Description |
|---|---|
| codesense | Local-first MCP server that combines graph analysis with vector search to produce architecture-aware implementation plans, intended for LLM-assisted work on codebases too large to hold in context. |
| chutes-js | Node.js client for the Chutes.ai platform covering language, image, video and audio models. Published to npm. |
| Scraping-API | Node.js API for scraping jobs, routing each request through plain HTTP or a stealth browser depending on what the target requires, with a job queue, proxy rotation and caller-set timeouts. |
| jamcommerce | JAMstack storefront on Next.js and Sanity. Every product and category page is prerendered, with catalogue search that runs in the browser against an index built at deploy. Live demo. |
| React-Redux-Auth-Boilerplate | React authentication starter: sign in, sign up, protected routes and persisted sessions on Vite, Redux Toolkit and shadcn/ui. |

A head-coupled 3D perspective engine. Webcam face landmarks drive the render camera so the display behaves like a fixed window, letting the viewer lean and see past foreground geometry. The bulk of the work is in processing noisy landmark data: depth derived from inter-ocular distance, calibration, exponential smoothing, rate limiting and outlier rejection, with pointer and recorded-path fallbacks for when a camera is unavailable or tracking drops.
Repository and writeup to follow.
