Software Engineer, 14 Years | Backend & Distributed Systems | Extreme Ownership | Building in the Agentic Era
I build distributed systems that don't break at 3am. Backend-focused Software Engineer with 14+ years shipping production software. Currently obsessed with agentic development — leveraging AI as a force multiplier while maintaining engineering rigor.
IntexuraOS — AI-native personal operating system
- 24 services | 338 API endpoints | 327K lines of TypeScript
- Multi-provider LLM orchestration (5 providers, 17 models, "council of experts" pattern)
- WhatsApp-first interaction with autonomous code execution
- 95%+ test coverage | 21 CI verification scripts | Extreme Ownership mindset
Building AI agents that use apps as tools — not another app with AI bolted on.
Primary: Java (13 years), Spring Boot, TypeScript, Python Backend: Node.js, Fastify, Spring WebFlux Data: PostgreSQL, MongoDB, Firestore, Redis Cloud: AWS (10 years), GCP (Cloud Run), Azure Infrastructure: Docker, Terraform, Kafka AI/LLM: Claude, GPT, Gemini, Perplexity — orchestrated via custom abstraction layer
Extreme Ownership doctrine: If the code broke, I own it. If requirements were unclear, I should have clarified. No excuses.
Engineering rigor:
- 95%+ branch coverage required — every commit validated
- Strict TypeScript mode — no
any, no surprises - Infrastructure as Code — if it's not in Terraform, it doesn't exist
- CI enforcement — "my part passes" is not a valid state
Agentic development:
- AI models as a "council of experts" — each has strengths
- Abstract behind contracts, route intelligently, synthesize results
- Ship faster while maintaining quality standards
