Long time Ruby wizard, with 10+ years of experience in full-stack web developments.
Eat, sleep, code, repeat. I've built software solutions ranging from college to fintech and banking platforms. Web applications serving the 100k users. Let me find the solution also to your problems.
I see programming as craft. Code is tool, it needs to have purpose, ellegance and efficiency to communicate and execute well. As a result, I produce software of the top quality, highly readable for future maintainers, functional and tested well.
