Always forward, no retreat. But with a little meow.
I design and build distributed systems ready for real production.
Main languages: Golang 🐹 and Rust 🦀.
15+ years in software engineering and DevOps / Kubernetes (☸️).
Focus: high availability, security, and elegant simplicity.
- 🧠 Architecture & Design — from concept to deployment.
- ⚙️ Reliability & HA — graceful degradation, idempotent flows.
- 🛠️ Platform Engineering — CI/CD, GitOps, scalable developer experience.
- 🔐 Security by Default — zero trust, defense in depth, verified builds.
- 📈 Observability — logs, metrics, and traces that speak truth.
- Senior Architect at Data Secrets Lab — I designed and implemented the backend and built a platform for ML engineers.
- Creator of Commucat — an ultra-secure p2p messenger with strong privacy and zero metadata leakage.
“Even cats deserve encrypted meows.”
| Tier | Stack |
|---|---|
| 💎 Primary | Golang, Rust |
| 🌈 Also Used | TypeScript (Next.js, React), Kotlin, Swift, and a bit of C# |
No endless tech stacks — only what really matters.
- Distributed-first mindset — events, queues, and safe retries.
- Operational discipline — GitOps, immutable infra, canaries, autoscaling.
- Data clarity — strong contracts, deterministic migrations.
- Resilience — recover, retry, never break silently.
- Security — everything encrypted, nothing trusted by default.

Focus: graceful failure, fast recovery, and zero drama.
- 🐈 Commucat (OSS) — private, encrypted, federated messenger.
- ⚙️ Rust utilities — cryptographic experiments and network tooling.
- 💬 Side projects — from pastebins to protocol explorers.
- High availability is not optional.
- Simplicity is hard, but sacred.
- Observability is part of design.
- Security is a habit, not a feature.
- If it’s hard to do, it’s probably worth doing.
