Software Engineer

Turning unique challenges into elegant software through research and experimentation

About Me

Tech enthusiast and software engineer specializing in distributed systems, blockchain protocols, and AI automation. I craft precise solutions across the full stack—from enterprise backends to smart contracts to autonomous AI agents. My approach: treat every technology as a

tool, not a solution

. From system architecture to protocol design to intelligent automation, I focus on deep problem understanding and relentless iteration to deliver real value. Technology should

fit the problem, not define it

Areas of Expertise

Backend & Distributed Systems

Building scalable, maintainable architectures that handle complex data flows and integrations. Experienced in unifying disparate systems, implementing enterprise-grade authentication, and ensuring data consistency across distributed services.

Blockchain Development

Architecting DeFi protocols from the ground up—from AMM implementations to cross-chain bridges, lending platforms to governance systems. Deep understanding of smart contract security, on-chain optimization, and blockchain-specific architectural patterns.

AI & Automation

Researching and implementing AI agents for advanced automation tasks. Focusing on practical applications where general intelligence can be applied to unstructured data problems, from customer support automation to specialized market analysis systems.

System Integration

Expert at bridging old and new—whether connecting legacy SOAP services to modern REST APIs, integrating blockchain protocols with traditional databases, or embedding AI capabilities into existing workflows.

Work Philosophy

I believe in:

Pragmatic Innovation: Using cutting-edge technology when it solves real problems, not just because it's new
Iterative Excellence: Building through experimentation—test, learn, refine, repeat
Tool Agnosticism: Selecting technology based on the problem, not forcing problems to fit the technology
Sustainable Solutions: Creating systems that are maintainable, scalable, and actually used
Continuous Learning: Every project is a research opportunity to expand knowledge and capabilities

What I'm Working On

Currently researching and developing

AI agent applications

for specialized automation tasks, while continuing to contribute to

blockchain infrastructure

and enterprise system development. Always interested in projects that present unique technical challenges and opportunities to apply cross-domain expertise.
