You will get your web app monitored, fixed and improved every month
Project details
Most small teams do not need a full-time developer. They need someone who knows their codebase and can fix things before users complain about them.
That is what this is. A fixed number of hours every month, spent on the things that quietly erode a product: slow pages, broken states nobody reported, accessibility gaps, dependencies drifting out of date, and the small features that never make it to the top of the list.
I run my own products in production, so I maintain apps the way I would want mine maintained. I work in small commits and ship during the month instead of disappearing and reappearing at the end with a wall of changes.
You always know where the hours went. Every month closes with a short written summary: what changed, hours used, and what I would do next. No lock-in, no minimum term. You renew because it was worth it, or you stop.
React and TypeScript codebases. Based in Buenos Aires, same timezone as US East.

About Federico
Frontend Developer | React & TypeScript | AI Features & Integrations
Buenos Aires, Argentina - 7:53 am local time
Based in Buenos Aires, same timezone as US East. Fluent English, end to end delivery, fixed quotes by project scope (not hourly guessing).
What I do:
- AI feature integration: chat/assistants (Gemini/Claude), vision, voice, or RAG, shipped to production with graceful fallbacks. From USD 900 (pilot scope from USD 300).
- Integrations & automation: payments (Mercado Pago/subscriptions), Firebase, third-party APIs, content pipelines and dashboards. From USD 700.
- Monthly retainer: maintenance, performance (Core Web Vitals), accessibility, and ongoing improvements. From USD 120/mo (5h).
Proof: an accessible medical communicator running in 39 languages at WCAG 2.1 AA, an AI cooking app billing live recurring subscriptions in production, and a content and ad-sales pipeline that runs a newspaper reaching about 15,000 people a month.
Stack: React, TypeScript, Firebase, Node.js, Tailwind, Gemini AI.

Health check in week one
I audit the app before touching anything: performance, accessibility, console errors and dependency risks. You get a short list ranked by impact, not a 40-page report.
We agree what the hours go to
You pick what matters from that list. Anything urgent that comes up during the month jumps the queue, and I tell you what it displaces.
