I'm a founding engineer in Bogotá, looking for the next thing. I ran engineering at Enttor, where I built the paid ads platform on Meta and TikTok and the Slack agent that runs it. Before that I worked on an e-commerce marketplace at Samsam. I have a master's from Universidad de los Andes.

Product engineer at Samsam, then founding engineer at Enttor. I did the master's while working the first job.

It started as the outbound engine, browser agents sourcing prospects and drafting the DMs. It ended somewhere else: Meta and TikTok campaign data normalized onto one metric schema, a rules engine that returns scale, pause or archive with a reason, and a Slack agent media buyers drive in plain language across 165 tools. The last product generated the ads outright, then took them back apart into editable layers on GPU workers.

A React Native and Expo app for shoppers and a Next.js dashboard for merchants, on NestJS services with Prisma and Postgres. I shipped both sides.
Deploys were manual when I arrived. I moved the pipeline to Azure and built the CI/CD that released to every client server on its own. I owned a Python and Flask reporting service running scheduled queries across client databases, and built the Power BI dashboards clients used to track headcount, turnover and payroll cost, replacing reports that had been assembled by hand.
It starts with data that does not fit a table, semi-structured, geolocated, high-velocity, multimedia, and asks what it is worth to whoever is holding it. Most of the time goes on governance, security and data quality, because that is what any decision made on top of it rests on. Coursework ran from applied data science and machine learning through recommender systems, knowledge engineering and privacy.
Mathematics for the formal side, management for the business side. Both ran alongside the undergraduate degree and closed before graduation.
Systems, algorithms and applied ML. Side projects in Python, TypeScript, Java and Swift along the way.
A national distinction and two AWS certifications.
2018Awarded by the Ministry of Education for a top-ranked score on Colombia’s national high-school exit exam (Saber 11).
2022Building, deploying, and scaling apps on AWS: IAM, Lambda, DynamoDB, S3.
2021AWS fundamentals: core services, security, architecture, and pricing.
Product, infrastructure, and a few things on the side.
Enttor's last product. Give it a brand's website and it scrapes the logos, colors and fonts, writes ad concepts with Claude, renders the images, then checks its own work with a vision pass. The harder half runs backwards: OCR and segmentation take a finished ad apart into editable layers, matching every line of text against 311 font families, so a media buyer edits on a canvas instead of rebuilding from scratch. Both vision workers run on GPUs.
A Slack bot media buyers talk to like a coworker. 165 tools across the Meta and TikTok ad APIs. Accuracy falls off long before 165 tools fit in context, so a router narrows every message to a shortlist before Claude sees it.
Two years in one repo. It sourced prospects from Instagram and LinkedIn, wrote personalized DMs and tracked every reply in one inbox, then in 2026 was refocused on paid ads: Meta and TikTok insights on one metric schema, scored against per-client thresholds. Row level security isolates every company from the rest, so a handler that forgets its filter returns nothing.
Text to looping motion graphics. Claude writes a self-contained HTML scene, screenshots it in headless Chrome at three timestamps to read back its own output, then patches what is wrong. Only a scene that clears the composition gate gets recorded to MP4.
A chat-first editor for LinkedIn posts. You paste a draft and argue with Claude about the hook until it lands, grounded by cosine search over a corpus of posts that actually performed. Three variations stream in parallel, one per hook angle.
The backend behind the outreach: Node services on a Mac Mini that keep authenticated browser sessions alive on four platforms, with Redis queues pacing outreach in minutes rather than milliseconds. Two teammates led it, I contributed the Instagram pipeline and session handling.
Before Enttor. A shopping marketplace: a React Native and Expo app for shoppers and a Next.js dashboard for merchants, on NestJS services with Prisma and Postgres. I shipped both sides.
