I build scalable Rails applications, APIs, AI integrations, and high-performance database solutions.

I've built and maintained full-stack web applications at Apptimum Labs using Ruby on Rails, Vue.js, React.js, and JavaScript, with a focus on clean architecture and performance.

I build secure REST APIs with JWT and OAuth, optimize PostgreSQL, MySQL, and Redis workloads, and manage deployments through Google Cloud, Heroku, and Capistrano. I've also integrated AI APIs, including OpenAI and vision/language models, into existing products.

Previously at Blackstack Software Solutions, I delivered Rails features, background workflows, and reliable test coverage while mentoring junior developers. My project work includes AI-powered virtual influencers, DearBrightly's tele-dermatology platform, Crowne Cards payment tools, and ForceBrands recruiting features.
