I'm an electronic engineer. I know what happens before the data reaches the code: the signal that has to be amplified, the filter that cleans it, the circuit that cooks itself if you get the maths wrong. I write software and that's where I want to be — but I write it knowing where the numbers came from, and that changes what I build.

Profile

I ask before I build.

I'm an electronic engineer from Universidad del Magdalena, graduating in December 2026. Circuits, signals, networks and radio on one side; Python, C++ and databases on the other. I want my career in the second half — but the first one is why I'm good at it.

What I like about this job isn't the code — it's understanding a problem that matters to somebody. That's why I ask a lot of questions, and why the things I build usually start as a conversation with the person who will use them. Most of what I write lives where nobody sees it: a driver, a query, a service that has to be right the first time.

And I don't only want to be measured by what I ship. I teach, I lead, I volunteer, and I get into things I don't know yet — that is as much a part of my work as the code is. I'm looking for a team that works the same way: people first, and the engineering as a consequence.

Beyond the code

The part a repository doesn't show.

I'd rather be judged by more than my commits. These are the things I keep doing even when nobody is paying me for them.

Teaching

I explain things for a living, too

I was the academic monitor for Electronics II — the university's monitor programme picks students for academic record and teaching vocation, and treats them as the seedbed for its future faculty. In practice it meant sitting with 70+ classmates who were stuck, writing the study guides I wish I'd had, and finding a plainer way to say a hard thing. I have also taught machine learning — how to clean a dataset and train a model that means something.

If I can't explain it simply, I haven't understood it yet. That rule has saved me more bugs than any debugger.

Volunteering & leading

I like building the team, not just the thing

Every leadership role I've had was volunteer work. I chaired the IEEE Robotics & Automation Society chapter at my university, ran the student branch's web platforms as webmaster, and co-founded ELECTRUM, an association that grew past 30 active members — organising workshops, events and the tools the group needed. Nobody was being paid for any of it, and that is exactly the point: people had to want to be there.

A group of volunteers only stays if the work means something to them. Learning that changed how I work with any team.

Research

I'm happiest with an open question

Research is the part I enjoy most: taking a question nobody has answered yet and staying with it long enough to get somewhere honest. AgroLumen started that way — how do you catch the fall armyworm in a maize field early enough to matter? — and ended as a solar trap with its own data.

I'd rather say «I don't know yet, let me find out» than pretend. It's slower on Monday and much faster by Friday.

Projects

Everything I've built, no first and second division.

University, work and my own nights, in the same list and the same size. Some were harder than others, and it isn't always the paid ones.

The ones from GC Foods have a story of their own: I arrived as an intern to a department with no development team, asked my colleagues what was broken and what they were stuck on, and took those problems to build the answer. The mobile app, the electrical graph and the maintenance portal I designed and built end to end; the SCADA already existed when I arrived — it was a fraction of what it is today — and I joined it and took it there.

Mach-T

A collaborative platform built for my university, on one idea: the academic work students accumulate — notes, guides, past exams — shouldn't die with each graduating class. It also hosts a marketplace for student ventures, with no middlemen. Expo Router on the front, Supabase behind it: PostgreSQL with row-level security, Deno Edge Functions, and a document store with private buckets and signed URLs where deleting really deletes the file. 121 database migrations so far. The trickiest part was uploading large files on Android, which needed its own sequential queue and the native file API.

The whole installation, made queryable

The plant's single-line diagrams existed only as CAD exports nobody could search. I rebuilt them as a queryable graph — 559 nodes, 552 connections, 100 panels, 8 transformers — reading the drawing's own layers and text annotations instead of guessing from OCR. Then I cross-checked it against four independent sources: the drawing geometry, the project's load schedule, the diagrams the building-management system draws on its own, and the panel manufacturer. A pre-commit hook refuses any commit that breaks the checks. The information about what feeds what existed only inside a drawing nobody could query; now you ask the installation a question instead of tracing a wire by eye.

The bench years

I'm not going to list them one by one: they're coursework, each one built with whatever I knew that semester. But they were years at the bench — a ball-and-beam rig holding a ball still on a bar, temperature control for an incubator, audio recognition, pulling a voice out of its instrumental, sumo robots, a pulse oximeter with sensors I made myself. That is where I learnt to model a system, to filter a dirty signal, and not to trust a measurement until I've checked it. None of it is on GitHub, because GitHub is where the code lives — not the soldering.

Evolutionary trading bots

A population of bots competing on Polymarket with simulated capital against real prices and order books — the code is read-only, it never signs or sends an order. A shared treasury hands out capital by measured, risk-adjusted performance and an evolutionary loop retires whatever doesn't work. The hard part isn't trading, it's stopping the system from fooling itself: the simulator was quietly gifting value to longshots, and the treasury was rewarding bots that simply sat on their capital. It runs unattended every 3 hours on GitHub Actions.

The oven, live and honest

A read-only SCADA/HMI in Python — 71 modules, ~31,600 lines — reading an Allen-Bradley CompactLogix PLC over OPC UA through Kepware and historizing to SQL Server. It was a small prototype when I arrived; I joined it and grew it into what maintenance uses today. Three things I am proud of: the seven zone motors were reporting a false running state (the app read a recipe setpoint instead of the drive's RUNNING bit — that is fake operating hours in Power BI); the oven had no production counter to divide energy by, so I traced the signals nobody was reading and published them; and I replaced polling with OPC UA subscriptions, cutting network traffic 93.9 % — 687 reads/s down to 42 changes/s, measured against the production server, with automatic fallback to polling if the subscription drops.

Gosper — Game of Life

Conway's Game of Life for iOS and Android, built to be worth watching. The catch: iOS forbids apps from compiling code at runtime, so no JavaScript engine can go fast on an iPhone — a seeded 1024×1024 board topped out at 7 fps. I moved the engine to C++ with 64-bit bit-parallel words and its own renderer: the same board now runs at 60 fps, with simulate-plus-draw down from 35 ms to 0.6 ms. Plus a curated library of about 40 classic patterns and a community layer on Supabase.

Thirty systems, one route, zero guesswork

The scheduled shutdown of auxiliary systems used to live in a PDF. Now it is an app (React Native + Expo) that walks the technician through the route: an offline checklist, a photo of each panel with the breaker circled, voice guidance that reads the card out loud, and an exportable history of who did what and when. My idea, my build, start to finish.

AgroLumen — solar IoT light trap

A solar-powered light trap that monitors the fall armyworm in maize, designed for fields with no reliable anything. The ESP32 raises its own Wi-Fi network and joins the farmer's at the same time, so it can be configured on site with no internet; it pushes telemetry to a Next.js dashboard when there's a link and stacks readings on a microSD card when there isn't, emptying the backlog before it goes to sleep. Built for the MYOSA Contest 2026.

Energy report, re-pointed

The plant's Power BI energy report wasn't reading the meters: it read 65 Excel sheets someone exported by hand, so it could never refresh on its own — a median lag of 27 days, and two tables frozen since March. I wrote the SQL views over the meter database, matched every table to its meter by comparing readings, re-pointed 57 tables and fixed a total that was under-reporting by 22.9 %.

One more thing

Tune the signal.

Move the pointer sideways to find the carrier. Lock it three times and the noise gives up. (Yes, this is what a link budget feels like.)

Let's build
something.

I'm looking for a team where people come first and the engineering follows — somewhere I can keep learning out loud and teaching what I learn. Junior engineering roles in automation, backend, data or security: on-site here in Santa Marta, in Barranquilla or Bogotá, or fully remote. I answer fast, and I'd rather have a real conversation than exchange keywords.
