At Tech Element IT, I build scalable EdTech, SaaS accounting, ERP, CRM, e-commerce, and POS platforms. I develop systems with Node.js, TypeScript, PostgreSQL, and Redis, and deploy production applications using Docker and AWS.

At Naria IT Solution, I built B2B/B2C OTA, SaaS accounting, newspaper, and holiday platforms. I also developed microservices and REST APIs, integrated third-party APIs, and built AI-powered travel solutions using OpenAI APIs.

At M360 ICT, I was a core engineer and team lead for Trabill, a multi-branch travel ERP/SaaS platform. I built travel, Hajj management, OTA, and accounting modules, and optimized SQL queries and Redis caching.
