At Lucred, I build and optimize backend services for secure fintech products processing thousands of daily transactions. I develop financial algorithms for loan risk assessment, credit scoring, and fraud detection using Node.js, Express.js, and TypeScript.

I've built fiat-to-crypto and crypto-to-fiat infrastructure, integrating payment providers with EVM-compatible networks. My work coordinates on-chain and off-chain flows, reconciles internal ledgers with blockchain confirmations, and supports ERC-20 transaction workflows.

I contribute to ERC-4337 account abstraction integrations, including paymaster logic and bundler interactions, while building monitoring for nonces, confirmations, retries, audit logs, and compliance reporting. I also automated Docker and Kubernetes deployment pipelines, reducing release cycles by 30%.

Previously at Nowtech Hub, I taught JavaScript, MERN stack, Python, and Django, mentored junior developers, and led workshops on design patterns, CI/CD, and development best practices.
