About Sahib Singh

I am a passionate Software Engineering student at KIET Group of Institutions with strong hands-on experience in building scalable backend systems. Currently interning at Decentro (YC-S20), I\'ve successfully developed and maintained high-performance Banking APIs handling daily requests. My previous internship at DivineTalk Astrology involved optimizing backend systems and implementing Elasticsearch, significantly improving application performance. I specialize in backend development using Node.js, Python, and Go, with expertise in databases (MySQL, MongoDB, PostgreSQL) and message brokers (RabbitMQ). Beyond professional work, I\'m an active competitive programmer (Pupil at CodeForces) and have secured multiple wins in national-level hackathons, including being a Grand Finalist in SIH 2023.
