About me
Computer engineer (UBA) and senior full-stack developer with 20+ years delivering web and mobile software for clients in Argentina, Germany, Australia, Ireland and New Zealand. Fully remote since 2012 — both embedded in engineering teams (pull requests, code review, async communication) and leading projects end-to-end as an independent developer.
I own the full cycle —database, API, responsive UI, testing and deployment— focused on production-ready apps (auth, billing, email, admin panel) and real-time systems.
For each project I define the architecture: I choose the database, frameworks and deployment strategy based on the client's real constraints —cost, connectivity and scale—. For example, a multi-model AI pipeline (LLM for text → generative audio) behind a secure proxy with async generation, hybrid SQLite/PostgreSQL persistence for an on-premise platform, offline-first architecture with sync and conflict resolution for mobile logistics, or multi-tenant RBAC for a SaaS.
Core stack: TypeScript · React / React Native · NestJS / Node.js · PostgreSQL · Docker.
Also: extensive earlier production experience with PHP, Java and .NET (C#).
Education
Master's equivalent degree in Computer Science Engineering: Ingeniero en Informática con orientación en Gestión Industrial de Sistemas. Completed a rigorous 6-year engineering program — an equivalent of a Bachelor of Science (B.S.) plus a master/specialization in Software Industrial Management — culminating in a Final Professional Project. Additionally, in May 2011, I successfully completed an English course through credit by examination.
What I deliver
- Complete product, from architecture to a UI ready for real users.
- Production-ready: auth, billing, email, admin, multi-tenant, RBAC.
- Deployment & ops: Docker, Nginx (reverse proxy, SSL), VPS and on-premise.
- Web & mobile (React Native / Expo, offline-first) and real-time data systems.
- AI features in production: multi-model LLM & generative-AI pipelines behind a secure proxy (async generation, polling, cost control).
- Other hard integrations: payments, electronic invoicing (AFIP) and real-time data.
How I work
Agile (Scrum / Kanban), Git with pull requests and code review, CI/CD and automated testing. Clear communication in Spanish and English. Experienced working on contract with international clients —Ireland, New Zealand, Germany and Australia— coordinating with distributed teams across time zones.
AI Workflow · Agentic Development
With 20+ years of production engineering as the foundation, I use AI tools to multiply delivery speed: Claude Code (Anthropic) in VS Code, Windsurf (Devin) and MCP (Model Context Protocol) servers, with custom skills and multi-step agent tasks. The result: team-pace coverage at individual-developer speed.
Interests · The sea
Beyond code I'm a surfer and sailor, and a maritime-forecast enthusiast. That obsession became product in Las Olas (a surf forecast engine) and La Marea (a real-time tide clock). More about this in Sea & Code.
Available for full-time remote roles, as well as contract and freelance work. Argentina (UTC−3, overlaps US business hours), fluent English. Reach me at admoggia@gmail.com
