Hello, I'm
Sina Soleymanzadeh,
A Back-end Developer based in Iran.

At Bitium Agency, a dynamic software company, I tackle diverse back-end challenges across a wide array of projects. My primary responsibilities involve designing, developing, and maintaining server-side logic using Node.js and managing databases with PostgreSQL. The varied nature of our projects requires adaptability and robust problem-solving to deliver tailored and efficient solutions.

As part of this international company focused on ride-sharing and CRM solutions, I was responsible for the full lifecycle of critical projects. Notably, I engineered and launched a new taxi application from the ground up for the Finnish market. My role involved building scalable back-end services, managing CI/CD pipelines for deployments, and implementing significant performance enhancements to ensure optimal user experience for both ride-sharing apps and CRM systems.

Spearheaded the complete architectural rewrite and development of a flagship project using Next.js and TypeScript. My primary focus was on significantly improving application performance, enhancing maintainability, and elevating the overall user experience (UX) through modern front-end practices and optimizations. I worked closely with stakeholders to translate requirements into intuitive and responsive user interfaces.

My role at Targoman evolved significantly. I initially joined as a Frontend Developer, building interfaces with React and Next.js. Within six months, I transitioned to Back-End development, working with Node.js and TypeScript. Subsequently, I took on the challenge of maintaining and enhancing a critical back-end project built with Golang and the Gin framework. This journey culminated in my role as a Full Stack Developer, where I contributed across the entire stack, including front-end (React, Next.js), multiple back-end systems (Node.js, Golang), and database management (MongoDB).
