About me

I’m Pritam Ghosh, a Senior Full Stack Engineer with 5+ years shipping Next.js, Node/Nest, Go, and GenAI systems—focused on ownership, performance, and maintainability over buzzwords.
Pritam Ghosh

I take fuzzy requirements and turn them into production-ready UIs and APIs: clear module boundaries, pragmatic tests, and CI that teams trust.

At Nykaa (Software Engineer II), I work on SuperStore engineering—shipping a production GenAI chatbot built on LangGraph with custom embedding-based semantic retrieval (no vector DB; product and commerce data converted to structured JSON embeddings for lightweight lookup), achieving 95%+ unit test coverage with Jest, and delivering a hybrid Next.js + Android experience that bridges web flows with native Android APIs.

Previously at Kaamwork, I helped deliver a Next.js / Nest.js SaaS stack with measurable gains in efficiency and release cadence. At Services & Consulting Force (Italy, remote), I supported a Next.js + Hugo hybrid for 500k+ daily users, SEO, and editorial tooling.

I document and learn in public via Tech Notes on this site and keep my PDF resume aligned with what you read here.

Working Area

Engineering solutions: pragmatic and user-focused

“People do not care how much you know until they know how much you care.” - Teddy Roosevelt

ui-ux

Web Application Development

Full-stack web applications with Next.js, React, and Tailwind CSS—from authenticated dashboards to public sites—with performance, accessibility, and technical SEO treated as part of the product, not an afterthought.

Backend Development

Constructing a robust backend using Node.js, Express, and TypeScript. Ensuring seamless data management with databases like MySQL, Postgres, and MongoDB. My solutions are designed for scalability and efficiency.

ui-ux

AI Integration

Ship production-ready GenAI features: conversational chatbots, embedding-based retrieval pipelines, and LangGraph-orchestrated workflows integrated with your existing TypeScript/Node.js stack. No generic demos; I have done this in production at Nykaa scale.

ui-ux

Automation Testing

Implementing automation testing with tools like Puppeteer and Selenium. This ensures high-quality, bug-free applications by automating repetitive tasks and testing workflows.

ui-ux

CLI Tools Development

Developing CLI tools to facilitate quick actions and streamline development processes. These tools are designed to enhance productivity and simplify complex tasks.

ui-ux

Cloud hosting, deployment & CI/CD

Design and automate CI/CD pipelines and cloud deployment on AWS, Azure, or GCP — from build to production rollouts with sensible guardrails.

ui-ux

SEO & performance

Technical and on-page SEO: crawlability, metadata and structured data, Core Web Vitals and page speed, sensible site architecture, and measurement with analytics. I align content and implementation so pages are discoverable, fast, and maintainable—not generic “keyword stuffing.”
