In the 2026 tech landscape, writing code is just the baseline; architecting solutions that solve real business bottlenecks is the true value. Coming from a background in Operations Management—where I reduced inventory discrepancies by 30%—I build production-ready applications that are secure, scalable, and user-centric.
I specialize in AI-assisted development, leveraging tools like Google Gemini and Prompt Engineering not just as novelties, but to automate workflows, reduce inter-party transaction costs, and deliver measurable business impact.
