Full-Stack Engineer — Lahore, PK
Full-stack engineer with 3 years building production SaaS, cross-platform desktop, and real-time applications for clients across five countries. I care most about the part everyone skips: making it fast.

Clients & collaborators
Selected work
//01
A business OS that unifies CRM, inventory, POS billing and analytics in one workspace — configurable for eight different industries.
Next.js and PostgreSQL. Every sale updates stock, customer balances and ledgers across devices in real time. Barcode and QR billing, low-stock alerts, and OCR bill scanning to cut manual entry for shop owners.
//02
A desktop CRM for small-business teams that stays responsive on low-end hardware.
Next.js frontend, Node REST APIs, PostgreSQL, packaged with Electron into a single product. Bundle splitting, lazy loading and runtime data management cut memory 66% (300MB → 100MB) and cold start 8× (8s → 1s).
//03
A JARVIS-style voice assistant that runs entirely on your own machine — no cloud, no paid APIs.
A 3D particle orb on a Next.js canvas that you rotate mid-air and spark with hand gestures via webcam tracking (MediaPipe). Real-time three-way communication between browser, Python backend and Android phone over ADB — "open YouTube on my phone" executes on the device.
//04
Classifies Windows executables as malicious or benign without ever running them.
Dual-model ensemble (XGBoost + TabNet) over 23 PE-header features extracted with pefile — entropy, imported APIs, section sizes. Consensus engine with feature-level explainability, optional VirusTotal cross-validation, and a Flask interface for analysts.
Also
Re-engineered a single web codebase into React Native mobile, Electron desktop and a PWA on a shared PostgreSQL backend, shipping a production build under 50MB.
REST APIs and TypeScript aggregation services over sales, purchase and banking data, powering day-book reports and 7/30-day dashboards.
A scroll-driven boutique storefront with 4K product showcases, and an interactive gallery of Blender-modelled historical statues with hover-activated lighting.
Authored and submitted the upstream security patch (PR #399) for the PostgreSQL backend powering STAC geospatial APIs.
View PR ↗What I do
I take products from an idea to something running in production — web, desktop and mobile on one shared backend, then tuned until it is fast on the hardware your users actually own.
Multi-tenant products with real-time data, billing and analytics. Next.js and PostgreSQL, built to stay coherent as they grow.
One codebase to web, Electron desktop, React Native and PWA — shared backend, consistent behaviour, one thing to maintain.
Live transaction flows where a write propagates to every connected device immediately, and the ledger is never wrong.
Bundle splitting, lazy loading, runtime memory work. I profile before and after, and I show you both numbers.
Classification pipelines, ensemble models, explainable predictions, and fully local speech and gesture interfaces.
Three.js product showcases and scroll-driven 3D experiences that load fast enough for people to actually see them.

Process
Understand the business, pick the data model, agree what ships first. You get a plan before anyone writes code.
Weekly demos against a working build. You steer as it takes shape instead of reacting at the end.
Deploy, profile, cut what is slow. Performance is a feature, not a phase you get to later.
Why work with me
I profile before I claim. 66% lighter, 8× faster cold start — measurements, not adjectives.
I have shipped a single product to web, Electron, React Native and PWA on a shared backend. I know where that gets expensive.
Ultron runs fully local. No cloud dependency, no per-token bill, no data leaving the machine.
Full source, documentation and deployment guides from day one. No lock-in, nothing you cannot hand to someone else.
