A programmable execution and wallet infrastructure for AI agents and advanced on-chain automation. The platform provides secure wallet management, policy-based execution, and unified access to DeFi and trading venues, enabling agents and applications to safely execute transactions, manage funds, and interact with both on-chain and off-chain protocols through a single abstraction layer.

• Designed and implemented the end-to-end system architecture (API, execution layer, wallet management);
• Built a secure wallet infrastructure with policy-based controls and programmatic execution;
• Designed abstractions for integrating DeFi protocols and on-chain trading platforms.
• Implemented real-time balance tracking and transaction activity monitoring across multiple chains;
• Developed APIs and SDK-style interfaces for AI agents (LangChain, MCP-compatible tools);
• Integrated key management and security primitives (KMS/MPC/AA exploration);
• Built internal dashboards for wallet management, policies, and live execution monitoring;
• Ensured scalability and performance across multi-chain environments;
• Defined product vision and technical roadmap from PoC to MVP.

An AI-powered real estate investment platform that helps users identify, analyze, and execute profitable property investments. The platform aggregates listings from multiple sources and combines market data, financial projections, and AI-driven analysis to provide clear, personalized investment recommendations.

• Designed and implemented the full front-end and back-end architecture;
• Built an AI-assisted chat interface to collect user preferences and personalize recommendations;
• Implemented complex data aggregation pipelines for real estate listings and market data;
• Developed AI-driven property analysis (rentability, cash flow, renovation costs, location insights);
• Built real-time communication between backend services and the frontend (WebSockets / pub-sub);
• Designed scalable APIs and database schemas optimized for large analytical payloads;
• Integrated external data providers and internal AI services;
• Implemented testing strategies for critical business logic and data flows.

An enterprise-grade DeFi API platform that provides unified and reliable access to decentralized finance protocols across multiple blockchains. The platform enables clients and developers to query on-chain data, interact with DeFi protocols, and build scalable financial products without managing the underlying blockchain infrastructure.

• Designed and implemented backend services for DeFi protocol integrations;
• Built scalable APIs aggregating on-chain data across multiple networks and protocols;
• Integrated with various DeFi providers, smart contracts, and blockchain data sources;
• Optimized data pipelines for performance, reliability, and high availability;
• Implemented transaction execution flows and protocol-specific logic;
• Improved API consistency, developer experience, and documentation;
• Debugged and resolved complex production issues related to blockchain edge cases;
• Wrote unit and integration tests to ensure correctness and long-term maintainability;
• Collaborated closely with product and infrastructure teams on enterprise requirements.

A liquid staking platform for institutional clients to stake Ethereum (ETH) more efficiently. The platform issues tradable representations of staked ETH (LsETH) that continue earning staking rewards while remaining usable in decentralized finance (DeFi) protocols. This approach improves capital efficiency and provides liquidity without sacrificing staking yield. The implementation is designed to meet enterprise requirements for compliance, custody, and high-availability infrastructure.

• Actively designed and implemented core backend services (Go) and APIs powering the liquid staking platform;
• Implemented frontend features and user flows in a React-based dApp interacting with staking services;
• Built and maintained integrations between frontend, backend APIs, and on-chain components;
• Reviewed, contributed to, and validated smart contracts used for liquid staking and reward distribution;
• Reviewed and collaborated on Python-based validator and staking infrastructure tooling;
• Implemented monitoring, logging, and error handling to ensure production-grade reliability;
• Collaborated closely with staking, validator, infrastructure, and compliance teams in an institutional environment.
