Summary
👤
Senior🎓
Top SchoolPrafful Javare is a Software Engineer II based in Berlin with 9 years of experience building scalable backend systems and data pipelines across adtech and high-throughput platforms. He has driven large migrations and performance improvements at Google (DV360 forecasting) and Delivery Hero, and reduced operational load by modernizing long-running pipelines and caching layers. Strong in algorithms and competitive programming—he actively contributed algorithmic solutions to the CodeToExpress challenge and maintains profiles on GitHub/Codeforces/Codechef under "profgrammer"—which fuels a disciplined, problem-first approach to engineering. Past roles span building high-scale practice platforms, real-time priority queues, and OAuth/certificate services, showing a mix of pragmatic engineering and systems design. He’s particularly adept at combining data engineering, privacy-aware logging, and result aggregation to make noisy large-scale signals usable for product teams. Outside work he misses hackathons, reflecting a continual curiosity for contest-style problem solving that informs his day-to-day delivery.
