Collins Thomas
👋 About
Hey,
I'm a software engineer with several years of experience building backend and platform systems for fintech, logistics, and productivity products. I spend most of my time designing APIs, modeling data, and keeping production systems healthy.
I've worked on products like GoPath (smart forms and information sharing), FXP2P (a peer‑to‑peer FX marketplace), LendMe (a loan app with tens of thousands of users), early versions of Alcott (logistics & delivery), and internal tools.
I'm currently transitioning deeper into machine learning and AI — building things like a Nigerian food classification model and an HR Slackbot that uses retrieval‑augmented generation to answer questions from documents.
I'm open to backend, platform, and AI/ML‑adjacent roles, as well as collaborations on interesting products. Reach out: thomascollins582@gmail.com
