About

I'm a Software Engineer with a strong foundation in backend development and scalable system architecture. With a degree in Computer Science & Engineering from GGSIPU, I've contributed to impactful products across diverse sectors like EdTech, InsurTech, and TravelTech—delivering real-world solutions that are both robust and user-centric. I bring hands-on experience working in fast-paced startup environments, where I’ve owned and delivered core platform features end-to-end. My core engineering expertise lies in building distributed systems using Python, Node.js, and AWS. I'm well-versed in both relational (PostgreSQL, MySQL) and Non relational databases (Mongodb) , and experienced in working with high-performance tools such as Redis, Kafka, and Docker. I also bring a sharp command of data structures and algorithms—essential for designing efficient and scalable solutions. Beyond just writing code, I enjoy solving complex problems, building scalable solutions, and collaborating with cross-functional teams to drive innovation. I'm currently focused on expanding my technical capabilities and seeking meaningful collaborations that challenge me and offer opportunities to grow. If you're working on something exciting or want to brainstorm ideas, feel free to reach out on LinkedIn or at vaibhavz2402@gmail.com. Let’s connect and explore how we can create value together.
