Sulfikar Ali Nazar
Full-Stack Developer & ML Engineer
Software engineer with 15+ years of experience in architecting and coding interactive full stack applications. I’ve implemented and fine-tuned neural network architectures, including transformer-based models, and have expertise in diagnosing and improving model performance and selecting the right model for a given use case. I also use AI-assisted testing to ship faster without losing rigor.
Fifteen years, three chapters
I've spent more than fifteen years building software professionally — from enterprise Java Spring Boot backends to modern React and Next.js frontends — and I publish developer tooling through Bismi Solutions, including a Java library for Excel processing built on Apache POI.
On the machine-learning side, I've implemented and fine-tuned neural networks — including transformer-based models — matched models to real use cases and constraints, and put AI-assisted testing to work in day-to-day delivery.
This website is my own work end to end: a Next.js 15 application with an integrated AI assistant, an interactive interview code playground, and a suite of precision calculation tools. Explore it — it is the portfolio.
