I build backend infrastructure and smart contract systems for DeFi protocols and Web3 applications.
Most of my meaningful work has been at the intersection of on-chain logic and off-chain systems — designing how contracts communicate with backends, how reward distributions are calculated, and how integrations with external protocols like Lido, Ankr, and EigenLayer actually get built in practice.
At Aarna Protocol, I worked on the AFI407 liquid staking vault — a multi-protocol aggregation system designed to provide additional yield on LSTs by routing deposits across restaking protocols. I analyzed and extended the existing AFI801/802 vault architecture, contributed to the reward computation and distribution logic, and debugged critical calculation issues in the staking engine during active development.
Outside of that: I've shipped smart contracts across staking, token, and NFT use cases for freelance clients, built a production-grade RAG-based AI chat agent, and designed an on-chain credit scoring protocol deployed on Ethereum Sepolia.

Project history
- Architect and deliver custom full-stack applications for clients using Node.js, TypeScript, React, and PostgreSQL, resulting in shorter development cycles and higher client retention rates.
- Develop RESTful APIs, integrate AI/LLM services such as OpenAI and Claude, and build RAG pipelines for client platforms, which streamline data processing and enhance the accuracy of generated content
- Led end-to-end backend development of a distributed staking and reward-calculation platform integrating liquid restaking protocols (Lido, Ankr, EigenLayer) — designed system architecture, API layers with PostgreSQL and Redis, and core reward-distribution logic.
- Identified and fixed a critical reward-calculation bug in the staking distribution engine producing incorrect allocations across 3 integrated platforms; deployed fix to production with zero downtime.
- Designed scalable APIs enabling off-chain computation with on-chain data settlement, processing 5k+ transactions through the system.
- Collaborated directly with external engineering teams to reverse-engineer undocumented API specifications, unblocking integration delivery ahead of schedule
