Full-Stack Software Engineer focused on building reliable backend services and maintainable web platforms.

I prioritize long-term architecture, clarity and production-quality delivery.

• Backend development (Node.js, .NET, Java/Spring)
• Web applications with React, Next.js and TypeScript
• Database-driven systems (SQL and NoSQL)
• Cloud and infrastructure fundamentals (AWS, VPS environments)

Backend: Node.js · C#/.NET · Java/Spring · Python
Frontend: React · Next.js · TypeScript
Databases: PostgreSQL · SQL Server · MongoDB · DynamoDB
Cloud: AWS · GCP · Azure

Cross-platform desktop app for voice rooms. Tauri v2 shell, Rust signaling backend, Postgres 16, and a real WebRTC P2P mesh — the server never touches audio. Open source under MIT.

Stack: Rust (axum 0.8, sqlx, jemalloc) · Tauri v2 · Postgres 16 · WebRTC · React 18 (no build step)

Engineering highlights:

• Rust backend with sqlx compile-time checked queries and tokio::sync::broadcast per-room signaling hub
• JWT authentication via Sec-WebSocket-Protocol subprotocol — never via query string (prevents token leakage in logs, history, referers)
• Deterministic WebRTC glare avoidance (lexicographic user_id decides who creates the offer)
• Argon2id password hashing, ed25519-signed auto-updater
• CI/CD pipeline producing .dmg (ARM + Intel), .msi, .AppImage, .deb, .rpm from 4 parallel runners
• Zero build step on the frontend — React 18 + Babel standalone, vendored fonts

Around 4.4k LOC. Documentation covers architecture with sequence diagrams and a deployment handoff for VPS production (systemd, nginx, TURN, backups).

Saga pattern workflow library for Node.js, the browser and React Native. Typed builder, idempotency keys, retry with exponential backoff, automatic compensation on failure, distributed locking (Postgres / Redis) and crash recovery — with zero runtime dependencies.

Stack: TypeScript · Node.js 18+ · ESM + CJS · pg advisory locks · ioredis Redlock-style · vitest · tsup

Engineering highlights:

• In-process, lightweight alternative to Temporal / Step Functions — saga semantics without the worker fleet
• Typed result accumulation — ctx.results.<step>.<field> is statically typed across the chain via inference, no codegen
• Distributed lock protocol on top of pg_try_advisory_lock (auto-release on connection close — crash-safe) and Redis SET NX PX with Lua-verified token release
• Crash recovery: every step transition is persisted; the next invocation with the same idempotencyKey resumes from the last successful step
• Zero runtime dependencies, ~20 KB minzipped, separate bundler entries per storage adapter so pg / ioredis are loaded only when used
• 73 tests in CI (50 unit + 23 integration against real Postgres 17 and Redis 7) — covers concurrency, pg_terminate_backend mid-flow, lock TTL expiry, token-safe release, resume-after-crash
• Ships with llms.txt / llms-full.txt / AGENTS.md so AI assistants and coding agents can recommend it accurately
