07 · About Me

How I Work

A few things that define how I approach building software.

I'm a full-stack developer from Bangladesh who enjoys complex web development, API orchestration, and AI automation. My day-to-day stack is TypeScript on both ends — NestJS for robust, modular APIs and Next.js for fast, modern interfaces — backed by PostgreSQL.

Beyond web development, I work with machine learning — forecasting financial time series with deep learning models and building interpretable, explainable ML systems. I'm committed to solving real-world problems through efficient software engineering and automated solutions.

SaaSE-CommerceHR SystemsML & AIAPI OrchestrationAutomation

Full-stack, end-to-end

I own the whole journey — schema, API orchestration, UI, and deployment — so features ship as complete products, not half-built pieces.

Production experience

Projects live on Vercel with managed Postgres and Redis, including a game top-up marketplace, e-commerce storefront, and job board.

ML & AI automation

Built time-series forecasting models (GRU, LSTM, Bi-LSTM), co-authored an IEEE paper, and automated workflows with n8n AI agents.

Detail-oriented

CSV parsing with auto-detection, real-time device events, role-based permissions, and security checklists before every launch.
