Available for projects
Web development, online stores and custom applications. I work solo, directly with you, and ship something usable every two weeks.
A selection of products I designed, built and shipped to production.
Mobile app · Personal safety
Personal safety app for iOS and Android. It triggers emergency, suspicious activity and home burglary alerts, links trusted devices and lets you set an alert radius. Google sign-in and PIN lock.
Stack React Native · Expo · NestJS · PostgreSQL · Redis · Firebase
Web platform · AI-assisted document forensics
A platform for handwriting experts: it processes document batches, detects and crops every signature and suggests who it belongs to with a confidence score. Plus manual review, grouping by signer and a full audit trail.
Stack React · NestJS · FastAPI · Celery · PyTorch · PaddleOCR · PostgreSQL + pgvector
E-commerce · Online ordering
Mobile-first online store for an artisanal cookie brand. Catalog with promotions, cart, and delivery or in-store pickup. Takes card payments through Mercado Pago or bank transfers with receipt upload, and sends automated WhatsApp updates on every order status change.
Stack React · NestJS · PostgreSQL · Mercado Pago · WhatsApp Cloud API
Catalog, payments and shipping working end to end. Fast on a phone, which is where people buy from you.
Web or mobile, for the thing your business does every day and still does by hand.
Payments, WhatsApp, Google Maps, invoicing, your stock system. Getting them to talk to each other.
Online, fast, and with someone answering when something breaks.
A conversation and a review of how you work today. You leave with the scope written down and the quote closed, before paying anything.
Screens and flows before any code. You leave with a prototype you can click through and correct.
Deliveries every two weeks on a staging environment. Each stage ships something that works, not a progress bar.
Deployment, measurement and a month of adjustments included. Ongoing support after that, if you want it.
If it helps, I will reply with a rough scope and price. No commitment, no hour-long discovery call.
