Biography
I am a full stack developer who enjoys owning problems from architecture through deployment. My work spans MERN applications, Python services, React Native mobile apps, RPA automations, and AI agents - with a strong bias toward shipping reliable software and documenting what I learn along the way.
On the product side, I have led end-to-end builds for startups: designing APIs, implementing frontends, integrating third-party tools, and setting up CI/CD so teams can iterate quickly. On the automation side, I have delivered RPA solutions that extract data, orchestrate workflows, and reduce manual operations work.
I care about security and operability as much as features. One published case study on this site walks through detecting and removing a Git config injection worm - practical DevSecOps writing meant to help other developers respond fast if they encounter similar malware.
I am open to full-time roles, contract work, and collaborations on interesting technical problems. If you are hiring for full stack, AI, or automation work, the fastest path is email or a short intro call.
