Summary
👤
Senior🎓
Top SchoolSirjanpreet Singh is a software engineer with nine years of hands-on experience, currently headed to internships at AWS (Billing) and Expedia Group (Machine Learning) in 2026. He has applied research and engineering skills across industry and academia—from crypto meta-optics and image gradient reconstruction at the University of Washington to monetization systems at Ericsson. An active backend contributor to large open-source datasets like OpenGenus/cosmos, he implements algorithms and advanced DS solutions (Manacher’s algorithm, MO’s algorithm, dynamic programming and backtracking solvers) that power search and analytical tooling. Based in Seattle and grounded in the Paul G. Allen School and UW CS programs, he blends low-level algorithmic rigor with practical experience shipping billing, ML, and security-related systems. Notably, his work bridges research-grade image reconstruction and production-focused billing/mediation systems, showing versatility across the stack.
