Research, shipped.
Most AI never leaves the notebook. I build the version that ships, in front of real users and holding up under real load.

Full-stack reach,
AIdepth
Five years and 150+ products shipping full-stack systems and production AI. Now at Toptal, finishing an MSc in Applied AI at LSBU. I own the whole path, from product spec to a deployed, observable feature.
Full-Stack Engineering
End-to-end product ownership, from spec to a deployed, observable feature. React and Next.js on top, Django REST and FastAPI underneath, PostgreSQL at scale.
Frontend Engineering
Pixel-perfect React and Next.js interfaces in TypeScript, with Tailwind and Framer Motion. Figma to production, including the FlashWash Web3 site I led as frontend developer.
Backend Engineering
Django REST and FastAPI services with PostgreSQL at scale, plus async pipelines on Celery and Redis. The backbone of SuccessFundTrader, a FinTech platform managing $2M.
AI Engineering
Production LLM systems: RAG over private knowledge bases, Claude and OpenAI pipelines, and structured extraction. The Intent Hub pipeline turns raw web data into live purchase-intent signals for a B2B client.
Agentic Systems
Autonomous multi-agent systems that research, decide, and act. InvestiGator runs six cooperating agents unsupervised for hours, built on Google Gemini 3.
Applied ML & CV
PyTorch deep learning and computer vision in production, including a 3D-CNN violence-detection model deployed for live inference at app.axvene.com.
