About

I’m Adarsh Raj Sinha, a B.Tech graduate in Computer Science Engineering and a Full Stack Developer with hands-on experience in Java, Python, JavaScript, React.js, Node.js, and AWS. I specialize in building scalable, secure, and high-performance applications, with a strong inclination toward backend systems, APIs, and cloud infrastructure. Currently, I working as an Associate Software Developer at Firstsource Solutions, contributing to a large-scale multi-tenant crowdsourcing platform serving 100K+ users. My work includes designing RESTful APIs, implementing automation and disaster recovery solutions on AWS, improving system reliability, and maintaining high code quality through extensive testing. Previously, at Outlier AI, I reduced backend API latency by 30% by optimizing services and integrating LLM-powered workflows. I’ve also built and shipped real-world products such as Creatorship and RaypdPay, applying modern tech stacks to solve problems in creator economy and fintech domains. Alongside development, I’m passionate about problem-solving and continuous learning, with 500+ DSA problems solved and a top 5% HackerRank ranking. I’m now looking to grow opportunity that values engineering excellence, ownership, and user-first thinking, where I can contribute to impactful products while continuing to deepen my expertise in full stack and cloud-native development.
