Professional Summary

Senior Full-Stack Engineer and Principal Blockchain Engineer with 12+ years building and operating production software. Strong Web2 background in system design and leading delivery of scalable products: APIs, microservices, realtime systems, authentication, data modeling, and cloud operations. Deep Web3 ownership across Solana trading infrastructure, Solidity smart contracts, EVM dApps, DeFi systems, and low-latency on-chain products. Early-stage CTO and team-lead roles carried hands-on senior/staff/lead engineering scope: setting technical direction, designing architecture, writing production code, coordinating delivery, mentoring engineers, and owning releases and incidents. Core stack includes TypeScript, Node.js, NestJS, React, Next.js, Rust, Solidity, Solana, PostgreSQL, Redis, AWS, Docker, and Linux. Designed and led scalable consumer products to 10M+ registered users and approximately 500K peak concurrent users, integrated 19 Solana DEX protocols, and reduced a latency-sensitive execution path from 225 ms to 1-2 ms.

Profile

Hands-on engineering for systems that must scale and stay reliable.

Ahmad designs, builds, and operates end-to-end Web2 and Web3 products: system design for scalable apps, TypeScript APIs, React clients, Solidity smart contracts and dApps, Solana trading infrastructure, and production cloud operations.

His CTO and team-lead titles came from early-stage companies where the day-to-day scope was comparable to hands-on senior, staff, or lead engineering: writing production code, making architecture decisions, coordinating delivery, mentoring teammates, and resolving incidents.

He brings that scope to engineering teams through strong full-stack and backend delivery, principal-level blockchain depth (Solana and EVM/Solidity), pragmatic system design for scale, measurable performance work, and clear product-engineering collaboration.
