Software Engineer · Cisco
Rupanuga Prasad Mishra
I write backends that don't fall over. Spring Boot services, ML pipelines in Snowflake, and the occasional competitive programming contest — currently at Cisco working on their CCRC platform.
What I work with
Mostly backend stuff, some ML, and enough frontend to get by. I like making things fast.

Core concepts
Data structures, algorithms, OOP, DBMS, distributed systems, machine learning — the usual CS foundation, plus a lot of contest math
Tools
Git, Linux, Docker, Snowflake, SonarQube, NumPy, Pandas, Pygame — whatever the job needs
Other things I care about
Writing code that other people can actually read. Explaining technical things without jargon. Getting stuff done without burning out.
Where I've worked
- Built a caching layer for the CCRC webpage in Spring Boot. Latency dropped ~20%, which was nice.
- Wired up BotService APIs to bring AI features into the platform. The kind of work where you're connecting things that weren't designed to talk to each other.
- Got the codebase from "it works" to SonarQube A+. Took a while, but the maintainability payoff is real.
- Set up anomaly detection on Snowflake data — ML model catches attribute-level errors with 90%+ accuracy in production.
- Maintained a bunch of REST APIs that other teams depend on. The unglamorous work that keeps things running.
- Wrote 60+ DSA problems for online assessments. Turns out making a good problem is harder than solving one.
- Reviewed 150+ problem sets across C++, Python, Java, and Go. You start seeing edge cases in your sleep.
- Build a test-case generator that spits out 10 million lines per second. Useful when you need exhaustive coverage.
- Conducted 30+ technical interviews. Got pretty good at telling when someone actually understands recursion vs. memorized the pattern.
- Helped tune difficulty curves for global contests — balancing "challenging" with "not soul-crushing."
Things I've made
Some for fun, some for competition, all things I learned from.
That Time I Reincarnated As A Box
Aug 2025- A puzzle-platformer in Pygame. 8 floors, a narrative, and way more atmospheric effects than I originally planned.
- Has light casting, dynamic environments, NPCs, and a soundtrack. Basically I kept adding features until it felt like a real game.
- The control system took forever to get right — progressive difficulty is easy to design, hard to implement well.
Flight Navigation Optimization
Apr 2024- Built for Aerothon 6.0. Django backend, Dijkstra on a time-varying graph, and a map frontend to visualize routes.
- Models weather and traffic as dynamic edge weights. The hard part was making it fast enough to feel interactive.
Persistent Lazy Segment Tree
Dec 2023- A C++ template that does range updates, rollbacks, and persistence. 2x faster than naive for range ops, 30x faster rollback.
- I wrote this because I kept re-implementing the same thing for different contests. Now I just import it.

I'm open to full-time roles, interesting collaborations, or just chatting about algorithms over coffee (virtual or otherwise).
