CEO & Founder, DevCenter.dev
Full Stack Developer | Mobile Engineer | AI Builder
CSE, RUET • Saidpur, Bangladesh
I run DevCenter.dev — a dev agency where we build mobile apps, backend systems, and AI-driven products for clients. On the engineering side, I've been shipping production software since 2019 across Flutter, Node.js, Python, and more. Most of my recent work involves integrating LLMs into real products — not wrappers, actual systems with RAG, multi-agent orchestration, and computer vision pipelines.
A bit more about me
- 50+ repositories across personal and org accounts — 15+ mobile apps, 8+ backend services
- Running DevCenter.dev with 10+ active client projects
- I freelance on Fiverr and take on agency projects through DevCenter
- Studied CSE at RUET (Rajshahi University of Engineering & Technology)
- Based in Saidpur, Bangladesh — working with clients globally
- 7+ years of consistent commits since January 2019
- When I'm not coding, I'm probably configuring a Linux server or exploring new AI models

Mobile apps — Been doing Flutter since its early days. Built chat apps, AI assistants, gym management systems, media managers, and more. GetX MVC is my go-to architecture. I've also done native iOS (Swift/ObjC) and Android when the project needs it.
Backend systems — Node.js/Express for most production work, FastAPI when Python makes more sense, Spring Boot when Java is the requirement. Real-time chat servers, job queue systems, multi-tenant hosting, payment processing, auth systems — built them all from the ground up.
AI/ML — This is where things get interesting. I work with OpenAI, Claude, Gemini, and open-source models to build actual products. RAG pipelines, multi-agent systems, LLM orchestration with LangChain, and computer vision with TensorFlow/ML Kit. Built an AI app generator that takes a text prompt and outputs a working Flutter app with a live preview URL.
DevOps — Docker containerization, nginx reverse proxies, PM2 process management, shell scripting for deployment automation. I like my deployments boring and predictable.
