01 / WEB PLATFORM
Vettly.
A recruitment platform that brings candidate ranking, screening, messaging, and offer management into one workflow.
THE WORK
What I built.
Architected a polyglot microservices monorepo with seven ASP.NET Core services, two Python/FastAPI AI services, and two Go services, sharing PostgreSQL and Redis for caching and asynchronous events.
Built a Go API gateway as the single public entry point, with JWT validation, rate limiting, CORS, reverse proxying, and WebSocket passthrough.
Developed the React recruiter dashboard with TanStack Query and Zustand: a drag-and-drop Kanban pipeline, candidate deep dives, AI match scores, skill-gap breakdowns, and a bias detection interface.
Built semantic candidate ranking with sentence-transformer embeddings and asynchronous resume screening for AI fit scores and bias flags.
Implemented SignalR messaging and an e-signature offer workflow with PDF generation, Cloudflare R2 storage, and a SHA-256-hashed audit trail.
Deployed the frontend to Cloudflare Pages and 11 containerized backend services to Render, using Neon PostgreSQL, Upstash Redis, and GitHub Container Registry. GitHub Actions detects changed paths to rebuild and redeploy only modified services.
