Five portfolios, one click away
Full-Stack Developer
Full-stack web engineerFull-stack engineer building production Next.js + TypeScript apps — from schema to AWS deploy — with 4+ years of technical-lead delivery for US and UK clients, remote and UTC+5.
Open portfolio PrimaryAI Application Engineer
LLM / RAG product engineerA production app engineer who ships LLM features end-to-end — with a rare real-time C++/Rust systems background that makes streaming, latency and inference cost second nature — building RAG + agents in the open with evals and cost controls.
Open portfolio SupportingDevOps & Cloud Engineer
Cloud / platform / SREDevOps engineer who ships infrastructure as code — GitHub Actions → Terraform → Kubernetes, with monitoring baked in — backed by the real-time, fail-safe discipline of building production flight-simulation systems.
Open portfolio High-valueBlockchain & Web3 Developer
Smart-contract & dApp engineerSolidity engineer who actually shipped on-chain: a real Ethereum counterfeit-product-detection system (smart contracts + encrypted QR), plus security-first, Foundry-tested contracts and full-stack dApp UX on Layer-2 — public proof over credentials.
Open portfolio Niche magnetFlight Simulation Engineer
6-DOF sim / C++ / XR engineerA remote-available engineer who has actually shipped full-motion 6-DOF FTD integration — SimConnect/Prepar3D, Brunner control loading, motion platforms, glass-cockpit EFIS and Varjo XR — a skill set almost nobody in the remote contractor pool can honestly claim.
Open portfolioEach lens is a self-contained portfolio written for that audience — its own work, skills and case. If someone sent you a direct role link, you’re already seeing exactly the right one.
