About

I’m Vishu Kalier, a software engineer focused on building scalable systems, improving engineering quality, and turning complex technical problems into practical solutions. My experience spans satellite data processing and geospatial workflows at NRSC–ISRO, global AI collaboration as a Chapter Lead at Omdena, and platform engineering work at Zomato. Across these roles, I have developed strong fundamentals in DSA, backend engineering, system design, data systems, and problem-solving under real-world constraints. I have also gone through interviews with top product companies, which helped me build a structured and repeatable approach to preparation. That same approach now shapes my mentorship work, where I help engineers strengthen Java, Spring Boot, DSA strategy, backend systems, and interview execution. Your profile also already positions you publicly as a mentor and consultant, which makes this angle coherent rather than forced. If you want to work with me on mentorship or technical career growth, you can explore my sessions here: Topmate - https://topmate.io/techbeast/page/DoJV2ctZbc
