What I'm looking for

I seek roles combining hands-on engineering with developer-facing communication—API design/documentation, Web3 or cloud engineering, mentoring, and improving developer experience in collaborative, growth-focused teams.

I am a software engineer and technical writer with experience building decentralized applications, cloud solutions, and developer-facing documentation. I blend hands-on engineering with clear, consumable technical communication to help teams ship reliable products.

At VertoFX I led developer relations and documented over 200 APIs using OpenAPI and ReadMe, created a Product Bible, and produced video content to onboard clients. I have led deprecation efforts and maintained API lifecycles.

As Web3 Engineering Lead at Lite Utilities I developed dApps, smart contracts, and backend systems using Solidity, Rust, Next.js, and Web3.js, while providing technical leadership and mentoring junior engineers. I also built full-stack scalable applications with Django/Flask and mobile apps with Flutter and React Native.

I have trained and supported learners as a cloud and AI instructor, optimized cloud environments on Azure/GCP/AWS, built microservices and LLM evaluation pipelines in Rust, and consistently emphasize documentation, testing, and developer experience in every role.
