Full-stack developer at Tech Talent Space, building Qalentis — an AI-powered hiring and HR performance platform. On the side I build open-source tools in Rust, Go, Zig, F#, Java, C# and Python, shipped with tests, CI and, where it fits, a live demo.
| Project | What it does | |
|---|---|---|
| kilim | Conflict-free collaborative editing: an RGA sequence CRDT in Rust → WebAssembly | demo |
| raft-lab | Raft consensus from scratch in Go, 500-seed deterministic fault injection | demo |
| chunkmap | Finds duplicated bytes across and inside files: FastCDC + BLAKE3, one static Zig binary | report |
| subdrift | Fixes out-of-sync subtitles: FFT cross-correlation, framerate drift, Viterbi for cut scenes · F# | report |
| twinlens | Near-duplicate photos via pHash + BK-tree, keeps the best shot, fully undoable · Python | report |

⭐ Featured — spring-kafka-orders
Two Spring Boot microservices that talk only through Apache Kafka: key-based ordering, parallel consumers with row locking, retries, a dead letter topic and idempotent consumers — each failure triggered by hand and covered by a test.
