All projects

A multi-tenant retrieval-augmented generation platform where every model, every retrieval strategy, and every chunking rule is a database row an admin can change from a UI — not an environment variable that needs a redeploy. Redesigned from a flat settings table into a versioned pipeline registry, with rank-based RBAC that survived a real admin lockout.

A Next.js portfolio with a self-built content system underneath it — draft/publish revisions, a section-based page composer, role-based admin access, and an admin-triggered JSON import pipeline for content — running on Vercel against a managed Postgres database.

A real-time messaging application with WebSocket-based delivery, secure authentication, and a performance-tuned frontend.

A production-grade real-time chat application built as six independent Go microservices. The architecture tackles WebSocket fan-out across instances via Redis Streams, JWT token rotation with race-condition safety, a three-layer blocking cache, and a raw-TCP WebSocket tunnel at the API gateway.

A Retrieval-Augmented Generation pipeline built from scratch with Ollama — no LangChain, no cloud APIs — evolved from a single notebook into a local Streamlit app with multi-document comparison and automatic query routing.

An AI-powered size-calculation backend for an e-commerce bra-fitting platform, serving real-time predictions to live Shopify storefronts.
