@asimmehmood
I build secure blockchain, fintech, backend, and Android products at scale.
What I'm looking for
I've built blockchain and fintech systems for Coinbase, Stacks, Fasset, and Merit, improving transaction throughput by 40%, supporting $5M+ in user assets, and migrating the Blockchain Naming System for over 50,000 legacy users.
I build secure Node.js and Go backends, smart-contract integrations, and distributed wallet infrastructure across EVM, Bitcoin, DeFi, AWS, and microservices. I've also developed Solidity bridge contracts, reduced ERC20 bridge transaction costs by 10%, and conducted smart-contract security audits.
Alongside backend work, I've led native Android delivery in Kotlin, building architecture, SDKs, CI/CD improvements, and complete client-facing products from requirements through release.
