Senior Software Engineer | Web3 & Blockchain Systems | Former Cto
Seasoned Software Engineer and Technical Leader with over 15 years of experience building mission-critical distributed systems. I specialize in bridging the gap between complex technical architecture and real-world business impact.
My journey spans from low-level electronics to high-level Web3 infrastructure. As a former CTO, I bring a strategic leadership perspective to engineering teams, ensuring that technical excellence aligns with organizational goals. Additionally, I contribute to the tech community as a guest professor, teaching Blockchain and Distributed Systems on demand.
I am a polyglot developer committed to using the right tool for each architectural challenge. While my current focus is the JavaScript/TypeScript ecosystem with Node.js (NestJS), I have a solid background in Java and experience with GoLang, always prioritizing scalability and resilient design.
Core Expertise:
- Architecture: System Design, Microservices, and Clean Architecture.
- Web3 and Blockchain: Ethereum, Smart Contracts, and Wallet Infrastructure (Privy, KMS, HashCorp Vault).
- Technical Leadership: Former CTO experience, Engineering Mentorship, and Roadmap definition.
- Polyglot Stack: Proficient in Node.js/NestJS, Java/Kotlin, and worked with GoLang, Elixir and Shell.
