A few products and systems I've helped design, build, and ship.
A monorepo platform that ingests real-time data from washpad equipment over MQTT, stores it in a time-series database, and surfaces it through a live operations dashboard and HMI screens.
A zero-trust SSH access proxy: a CLI, NestJS control-plane API, and web dashboard that issue short-lived SSH certificates instead of distributing static keys, with org-based RBAC and an encrypted secrets vault.
A React Native calling and messaging app backed by a NestJS SFU server (mediasoup + Socket.io) for real-time voice/video, with subscriptions and a ledger service for tracking call usage and billing.
An e-commerce platform for paint and hardware — a NestJS/Prisma backend, a React Native shopping app, and a Vite-based web app, sharing a seeded product catalogue.
From MVPs to production applications, including architecture, frontend, backend, authentication, payments, and integrations.
Modern web applications and cross-platform mobile applications with polished UX.
APIs, databases, realtime systems, background jobs, queues, and scalable backend architecture.
Docker, AWS, Azure, CI/CD, deployment, reverse proxies, monitoring, and production infrastructure.
I'm a software engineer focused on building real products, not just prototypes. I enjoy working across the stack — from designing interfaces and APIs to architecting databases, realtime systems, and production infrastructure.
I typically work with startups and businesses that need someone capable of taking ownership of a product and turning an idea or specification into something that actually ships.

Choose the right architecture, technology, and development approach.
Develop iteratively with frequent feedback and working releases.
Deploy, monitor, document, and continue improving the product.
