Featured Work

_{01 · AI DEVELOPER TOOL}

StressBugger

Finds the exact input that breaks your competitive-programming solution.

An LLM writes test generators, checkers and brute forces; each must compile, pass samples and agree with the others before it is trusted
Stress-tests ~1,000 inputs per minute in a hardened Docker sandbox (C++, Java, Python)
Shrinks failures to a minimal counterexample and only marks a fix verified after re-running it

Java 21 Spring Boot Spring AI React PostgreSQL Redis Docker

_{02 · ONLINE JUDGE}

CodeForge

An online judge built from scratch: Codeforces problems in, sandboxed verdicts out.

Compiles once, then runs every test with CPU, memory and output limits, reporting the program's real peak memory
Crash-safe queue: PostgreSQL leases with a reaper; Redis only wakes the workers
A Docker container per submission when self-hosted; one Kotlin codebase ships Web (Wasm), Android and Desktop

Kotlin Ktor Compose Multiplatform PostgreSQL Redis Docker

CodeForge: an accepted C++ submission with three passed test cases

_{03 · SYSTEMS VISUALIZER}

OS Simulator

Operating systems concepts you can watch run.

CPU scheduling (FCFS, SJF, SRTF, Round Robin, Priority) with live Gantt charts and waiting/turnaround metrics
Deadlock detection on resource allocation graphs with Banker's algorithm safe sequences
Memory allocation (First, Best, Worst, Next Fit) with fragmentation analysis

Kotlin Multiplatform Compose Wasm MVVM
