What I'm looking for

I’m looking to build end-to-end products using JavaScript/TypeScript with modern front-end and back-end tooling, partnering with teams to ship reliable features—especially search, reporting, and secure data workflows—while continuously improving my skills.

I’m an initiative-driven full-stack developer who thrives on shipping concrete results with JavaScript and TypeScript. I’ve built and owned back-end systems with Node.js and databases like MySQL, Redis, and MongoDB, including a spider back-end to scrape apartment listings and power a much more complete apartment search.

On the front end, I’ve led development of React-based engines and interactive search experiences, including an interface that lets users express preferences and weight criteria. I’ve also integrated back-end services with external APIs, generated reports and charts using BigQuery, automated deployments to AWS, and added tests to support front/back end reliability—then used the same attention to security and performance while migrating and improving internal applications.
