Gleison Batista
Senior software developer with eleven years in backend, nine of them in financial systems: investment banking, payments, and now crypto tax. Currently at Ledgible, working in Node.js and MongoDB on queue architecture, transaction tax categorization, and agentic workflows that handle data gaps automatically.
I like building tools that simplify workflows, increase automation and reduce errors. I also write here, mostly about the ideas underneath the things I use every day.
