Chamo
A personal-finance app that organizes spending on its own — it reads bank emails or screenshots, categorizes them, and lets you approve each one in a tap and plan with envelope-style budgets.

Abel Arismendy
Fullstack Developer & Product Engineer
I build products end to end — frontend, backend, mobile, and XR — and obsess over the details that make them feel effortless.

Profile
About Abel
I'm a fullstack engineer in Bogotá. I build from the database to the pixels, and treat design as part of engineering — not something bolted on at the end.
I came into engineering from graphic and motion design, and that mix still shapes how I work — on startup products, internal tools, and research demos that have to be clear, not just functional.
Experience
Where I've Worked
A few years across startups and a university research lab — product engineering, fullstack, and XR.

Rebuilt Creditop's web frontend from scratch on a more scalable stack, and added observability and product analytics so the team ships with confidence. I also work across the backend, taking features from idea to production.
