Full-Stack Product Development

Building complete web products across interface, application logic, APIs, databases and deployment.

Capability statement

This site is the example: a Next.js CMS with PostgreSQL as its system of record, pgvector semantic retrieval in the same data layer, and a separate FastAPI reasoning service, deployed together on one VPS.

Problems I solve

  • Coordinating frontend and backend development
  • Building admin and public interfaces
  • Designing data-driven UI
  • Connecting APIs and databases
  • Deploying multiple services together

Full description

I work across the full product stack — from CMS and frontend architecture to backend APIs, data storage, AI integration and VPS deployment. I'm especially interested in products where the user experience depends on several systems working together.
Evidence standard

Strengths

  • Shipped and operating a multi-service product (CMS + reasoning layer + one PostgreSQL/pgvector data layer) on a single VPS
