>WHO I AM

Crafting DigitalExperiences.

I'm Tahsin Ahmed, a Software Engineer with 5+ years of experience building scalable web and cross-platform mobile applications for startups, SMEs, and international clients. Over the years, I've worked across the full development lifecycle — from planning system architecture to deploying production-ready applications on cloud infrastructure. My core expertise lies in technologies like Node.js, React, Next.js, and Flutter, with a strong focus on performance, maintainability, and user experience. I've led development teams, collaborated closely with clients, and successfully delivered projects under demanding timelines while maintaining high code quality. I enjoy transforming complex business requirements into clean, efficient, and scalable digital solutions. Whether it's a SaaS platform, automation system, or modern mobile application, I approach every project with a problem-solving mindset and attention to detail. Beyond development, I value professionalism, clear communication, and building long-term partnerships through reliable work. I was recognised as Employee of the Year (2023) at Notionhive — not for writing the most code, but for solving the right problems. Got an idea, a half-built product, or something you vibe coded and need to take further? Send me a message or book a call.

I had the chance to work with Tahsin on a project for a foreign client, and it was a very smooth experience. He is easy to work with, always focused on solving problems, and never backs away from challenges. He takes time to research and comes up with solutions on his own. What impressed me most is how quickly he can learn a new tech stack and deliver within a short time. I truly enjoyed working with him and would gladly do so again.
