Senior Full-Stack Engineer

I'm drawn to complex problems that require both systems thinking and careful execution. There's satisfaction in taking a messy, ambiguous requirement and turning it into something clear, reliable, and maintainable. I'm comfortable owning systems end-to-end, which means I think about architecture, data integrity, performance, and long-term maintainability from the start. I work best when I can collaborate closely with stakeholders to understand real constraints and business needs. My approach is disciplined but not rigid—I prefer proven solutions that fit the problem, and I value clarity and reliability over novelty. What motivates me is building systems that genuinely help people do their work better, with less friction and more confidence.
