Brian Jemilo II / Services
Node.js and TypeScript backends
I build backend services in Node.js and TypeScript. Usually Fastify or NestJS on Postgres and Redis, sometimes Express or Hapi when that's what you already have, and always in Docker so development and production run the same way. AWS or Cloudflare, depending on your setup. Available for contract and full-time backend work.
Work I've done
- At Modernizee I built a service from nothing that turns live project data into finished PPTX and PDF decks. Fastify, Node, Postgres, Redis, S3, and a real test suite that covers rendering, generation, and the UI.
- At Cashear I wrote the Node pipeline that pulls from music industry APIs and processes tens of thousands of PDFs a week.
- At Health iPass I led ten engineers on React and Node healthcare apps and set up the CI/CD that got them onto AWS.
- At Conversant Media I replaced a legacy reporting tool. That saved about $600,000 a year. I also tuned Greenplum query performance for the analytics workloads.
How I work
Strict TypeScript. Tests that run in CI, using Node's own test runner, Jest, or Mocha, whichever your repo already has. Pull requests small enough to read on a phone. Docker from the first commit so demo, review, and production all match.
Tools
Node.js 24, TypeScript, Fastify, NestJS, Express, Hapi.js, Postgres, Redis, Kafka, RabbitMQ, WebSockets, Docker, GitHub Actions, AWS, Cloudflare Workers
Things people ask me
- Can you take over a Node codebase someone else wrote?
- That's most of my contract work. I read it, get it running in Docker, put tests around whatever is about to change, then ship.
- Which frameworks do you use?
- Fastify or NestJS for new work. Express or Hapi if that's what you have. I pick what your team can maintain after I'm gone.
- Do you do the frontend too?
- React, Vue, or Angular. One person can own a feature from the database to the button.
Other things I do
RAG and LLM engineering
Chatbots and agents that answer from your own documents, with citations, and hold up in production.
API development and integrations
REST and WebSocket APIs, plus third-party integrations.
Web application development
React, Vue, Angular. New builds, or modernizing an older codebase.
