✨😺 Ducheved — Senior Architect ��☁️

Always forward, no retreat. But with a little meow.

---

🐾 TL;DR

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.

---

🧩 What I Do

• 🧠 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.

---

🌍 Now

• 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.”

🦄 Languages and Tools

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.}

☁️ My Architecture Aesthetic

• 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.

  U[Users 😺] -->|HTTPS/gRPC| G[Ingress / API Gateway 🚪]
  subgraph K8s [Kubernetes ☸️]
    G --> S1[Service A]
    G --> S2[Service B]
    S1 <-->|async| MQ[(Message Bus)]
    S2 <-->|async| MQ
    Cache[(Redis Cache 🧊)] <--> S1
    Cache <--> S2
  end
  S1 --> DB1[(PostgreSQL 🐘)]
  S2 --> DB2[(Object Storage 🗃️)]
  subgraph Observability
    OTEL[OpenTelemetry 👁️] --> Metrics[Metrics 📊]
    OTEL --> Traces[Traces 🔍]
    OTEL --> Logs[Logs 📜]
  end

🧪 Selected Works

• 🐈 Commucat (OSS) — private, encrypted, federated messenger.
• ⚙️ Rust utilities — cryptographic experiments and network tooling.
• 💬 Side projects — from pastebins to protocol explorers.

💡 Principles I Follow

• 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.
