I build the quiet machinery that makes a company faster
I'm Alejandro, a full-stack developer in Bogotá. Most of my work is automation and data: scripts that do in seconds what used to take an afternoon, and dashboards that answer a question before anyone has to ask it.
I studied International Business before I learned to code, which turned out to be useful — I can sit in a finance review and a code review on the same day and translate between them. With Python, Java and Power BI I've rebuilt real financial workflows, and the part I care about is simple: fewer manual hours, cleaner numbers, calmer teams.
Away from the keyboard it's cinema, photography and music — mostly loud.
Listed the way I actually reach for them — the three at the top of each card are where most of the work happens.
Three years turning manual, error-prone processes into systems a team can run without me. The title on the door says Analyst — the actual work has been Python automation, systems integration, and the data pipelines other people's dashboards sit on top of.
Analyst & Developer
Sep 2022 — Now- 01Designed and built EDI billing integrations end to end — one custom system per client, mapping each client's own data format into ours.
- 02Built the Python automation layer behind our reporting — pulling, validating and reshaping data so what took a full day took minutes. Cut reporting time 90%, about 45 hours a month back to the team.
- 03Modeled the financial data feeding weekly Power BI and Looker Studio dashboards — the kind stakeholders actually used to decide, not just look at.
- 04Owned more than eight projects end to end, from technical scope to delivery — customer satisfaction rose 25% over that stretch.
