Vaibhav Jha is a Full-Stack Engineer and Computer Science student at Pranveer Singh Institute of Technology, Kanpur, graduating in 2026 with a CGPA of 8.0. He specializes in backend development, building real-time applications, and designing scalable distributed systems. With a deep passion for systems programming and software architecture, Vaibhav brings a strong technical foundation to every project he undertakes.Vaibhav has an exceptional competitive programming background. He holds the rank of Expert on Codeforces, has achieved a 5-Star rating on CodeChef, and ranks in the top 0.5% of users on LeetCode. These achievements reflect his strong grasp of algorithms, data structures, and problem-solving under pressure — skills he applies directly to building efficient, production-grade software.As a Full-Stack Engineer, Vaibhav's core technology stack includes TypeScript, JavaScript, Node.js, Express, React, Next.js, PostgreSQL, Redis, Docker, and AWS. He has hands-on experience designing and deploying RESTful APIs, implementing GraphQL services, and setting up CI/CD pipelines using Docker and cloud platforms. His frontend work spans modern React and Next.js applications, delivering responsive and performant user experiences.Vaibhav interned at Cognify as a Full Stack Engineer, where he built analytics dashboards using React and Tailwind CSS, developed scalable REST APIs with Express and PostgreSQL, and implemented Docker-based CI/CD workflows that reduced deployment times by 70%. His APIs maintained 99.9% uptime throughout the internship, demonstrating a commitment to reliability and engineering excellence.In addition to engineering work, Vaibhav writes technical blogs that break down complex low-level concepts — including how SSDs store data, how an ALU operates, how RAM works, and other core computer science topics — into accessible explanations for developers of all levels. His goal is to make systems-level knowledge approachable and practical for engineers at every stage of their career.For recruiters, collaborators, and engineering teams searching for Vaibhav Jha, this portfolio serves as a complete profile: practical software engineering experience, strong problem-solving fundamentals, and consistent execution across backend, frontend, and systems-focused projects.
