What I'm looking for

I’m looking for a role where I can build secure smart contracts and scalable backend services, integrate AI agents for trading automation, and lead delivery end-to-end with global teams and a strong engineering/security culture.

I’m a blockchain and Solidity developer with 9+ years in IT, including 6+ years specializing in blockchain development and 1+ year building AI-driven trading agents and automation solutions for decentralized ecosystems. I focus on delivering high-impact software like financial DApps, AI agent platforms, and enterprise-scale data applications for real-world outcomes.

I’ve worked on mission-critical blockchain systems with strong security and reliability. I’ve implemented Role-Based Access Control (RBAC) using Zitadel, built multi-token and automation modules (ERC20/721/1155, ERC4626), managed multisig operations, and used Chainlink, The Graph, OpenZeppelin, Gelato, and Defender/Keepers to power production-grade smart contract workflows and decentralized automation.

I also bring a strong AI + backend perspective, building prompt-driven AI agents and conversational workflows (Bedrock, ExpressJS, AWS Lambda, DynamoDB, OpenSearch) to support intelligent strategy generation and automation. Earlier in my career, I’ve led engineering delivery as a Product Owner/Technical Lead for cross-functional teams, mentored over 20 team members, and improved release quality and testing efficiency through structured QA and automation.
