Full-stack developer · Argentina (UTC-3)
For teams that depend on web data and can't afford for it to break quietly. I build scrapers, data pipelines and the systems around them: queues, retries, recovery after failures and monitoring. I work async, with written updates.
Currently taking on new pilots. I reply within one business day.
Case study · due-diligence platform
Measured on the first 20 reports.
01 / Case study
A web platform that produces due diligence reports on people and companies. It collects data from 38 source modules in parallel and assembles the results into one report. The client uses it internally, in production. I built the backend, the API and the web app on my own in about three months.
Redis queues are split by type of source, each with its own worker, so a heavy module doesn't hold up the light ones. A dispatcher shares capacity between accounts.
About 1,700 automated tests, and CI runs on every pull request.
Client and data sources anonymized.

Email me02 / How I work
Tell me what data you need, where it comes from and how often.
Scope, price and delivery date are agreed in writing up front. You get a working deliverable, then decide whether to continue.
Each week you get a written update on what's done and we agree on what comes next. You can write to me in between if something looks off.
Sources change without warning. On a monthly retainer I monitor your collection, handle breakages quickly and send a written report each month on what ran, what failed and what I did.
03 / Personal projects
A debt management app. Log what you owe across credit cards, Mercado Pago and informal debts, then track purchases, installments, due dates and totals for each creditor.
A booking SaaS for businesses that run on appointments. Clients book themselves, each professional has their own schedule and services, and each business gets its own page.
A web app that estimates what a Steam game costs in Argentine pesos. It reads Steam's store data, adds taxes and converts at the official, MEP or crypto rate, and serves results from the edge cache.
