01 — Identity

One engineer, the whole stack.

Senior freelance developer since 2018. Top Rated Plus on Upwork and a Level 2 Seller on Fiverr, with a 5.0-star average across 700+ combined reviews.

02 — Architecture

Ideas, pulled apart into layers.

Every product starts as a stack of decisions: the interface people touch, the API behind it, where the data lives and how it all deploys. I own those decisions from architecture through deployment.

  • Interface
  • API
  • Data
  • Cloud

03 — Build

Web, mobile, backend and AI.

React and Next.js on the web. React Native on iOS and Android. Node.js, Express, MongoDB and Firebase behind them. AI where it earns its place: scored data rooms, generative image pipelines and brand-intelligence APIs.

  • Next.js
  • React Native
  • Node.js

04 — Connect

Services wired into one workflow.

REST and GraphQL APIs, Firebase, secure payment integrations, and AWS, Docker and CI/CD underneath, so each surface talks to the same source of truth.
