Hey there! I’m a Senior Software Developer with over 5 years of experience building everything from high-performance web apps to smooth mobile experiences. My bread and butter is the JavaScript ecosystem—specifically Node.js (NestJS/Express) on the backend and React/Next.js on the frontend. I’ve spent a lot of time architecting scalable APIs, managing complex databases like PostgreSQL and MongoDB, and leveraging AWS to keep things running like clockwork. Whether it's solo-flying a project or collaborating with a team, I’m all about writing clean, maintainable code that actually solves real-world problems. I’m currently looking to dive into a long-term freelance role where I can really take ownership of the backend logic and API development. I’m super comfortable working independently and I’m a big believer in clear, proactive communication—especially when it comes to hitting those daily milestones. I’m ready to sync up with your US Eastern Time schedule and bring some high-quality, "no-fuss" engineering to your project. Let's build something awesome together!
