What I build

I work across the backend and the full stack - from the data model up to the API surface. A few of the things I'm brought in to do:

• 01

  Backend Architecture

  Designing services that stay fast and correct as load grows - clean domain boundaries, event-driven flows with Kafka, and data models built to scale.

• 02

  API Development

  REST and real-time APIs that are predictable, well-documented, and pleasant to build against - from request contracts to websockets.

  Auth & Security

  Authentication, encryption, and PKI done properly - signed tokens, digital signatures, and AES-256-GCM / RSA-OAEP payloads that hold up.

  Performance Optimization

  Profiling and tuning the hot paths - queries, caching, and throughput - so systems stay responsive when traffic spikes.

  Cloud & DevOps

  Shipping to AWS and Vercel with sensible pipelines, so deploys are boring and uptime isn't something you think about.

  Integration

  Wiring systems together - third-party APIs, browser extensions, and automation with Playwright and Selenium that removes manual work.
