Rawalpindi, Pakistan4y exp

“Unity developer with shipped Meta Quest VR/MR experience on a multi-game "Nexus" arcade project, contributing to bowling mechanics, racing AI, hand poses, and QA-driven bug fixing. Also builds full Unity projects solo (airplane and taxi simulations), handling everything from physics and controls to level design and aggressive mobile performance optimization (targeting ~1GB devices).”

“Full-stack software engineer with a strong React Native focus who is independently building RapidJob, a two-sided mobile app for local gig work and extra income opportunities. He owns the entire stack—React Native frontend, Node/Express backend, MongoDB, AWS S3, and real-time updates via Socket.io—and has already launched a beta with early user feedback driving product changes like social login and navigation updates.”

“Backend engineer who built and scaled a FastAPI-based backend for an AI-driven maintenance system automating vendor sourcing/bidding/communication. Emphasizes async, message-driven architecture with strong observability and state-machine-driven workflows, plus robust webhook/idempotency patterns to prevent duplicate/out-of-order events from causing bad bids or state changes.”

Junior Machine Learning & Full-Stack Engineer specializing in applied AI systems

Los Angeles, CA2y exp

“Master’s thesis focused on building and deploying a gait-based biometric authentication system using mobile accelerometer time-series data as an alternative to passwords/2FA. Emphasized real-world robustness by addressing sensor noise and variability (phone placement, walking speed, footwear) and improving safety using biometric metrics like FAR/FRR and EER, while collaborating closely with a non-ML thesis advisor.”
