What I'm looking for

I’m looking for a team where I can deliver scalable features, improve performance and reliability, and streamline delivery pipelines—turning engineering work into measurable reductions in cost, latency, and execution time.

I’m a Software Engineer who builds and scales production systems with a strong focus on performance and cost. In my recent role, I reduced CI execution time from 5 minutes to ~1 minute with GitHub Actions, scaled a patient billing process by 250%, and built a patient budget tracking tool managing over $1 million per year and ~400 active patients per month.

Previously, I improved fraud verification speed by 75% by implementing recursive analysis and data aggregators, and I cut farm report generation time by 96% by adopting more efficient PDF libraries. I also optimized page performance by around 40% using a BFF approach, and earlier I improved application load and bundle size by optimizing Webpack and adopting tree shaking with libraries like Vuetify and Moment.
