What I'm looking for

I am looking for remote or hybrid back-end roles that allow me to leverage my skills in Java and Node.js while working with React.

I am a mid-level software engineer with over 3 years of experience in back-end development, specializing in Java and Node.js. My journey began at ZeroBounce, where I modernized high-throughput email-validation services, boosting engine throughput by 15% through innovative techniques like non-blocking I/O. I take pride in delivering clean, test-driven code and have successfully shipped multiple production web applications within tight deadlines.

Currently, I work as an Independent Software Engineer, where I design and implement full-stack solutions using Next.js for various clients. My focus on automation and performance has led to significant improvements in API latency and customer satisfaction. I am passionate about leveraging AI in development and continuously seek to enhance my skills in DevOps practices.
