About

I’m Santanu Mukherjee, a software engineer focused on building production-grade mobile and backend systems.

I work primarily with Flutter on the client side and design scalable backend architectures using cloud services, event-driven systems, and relational data models. My work is driven by performance, maintainability, and long-term scalability — not just getting things to work.

This blog is a place where I write about:

• real-world engineering decisions
• system architecture and trade-offs
• performance bottlenecks and optimizations
• lessons learned from building and shipping products

Most articles here are based on hands-on experience, not tutorials rewritten from documentation.

Background

Over the years, I’ve worked on:

• cross-platform Flutter applications (mobile & web)
• backend systems handling real production traffic
• cloud-native workflows using AWS, serverless functions, and managed databases
• data modeling and search for complex systems like email platforms

I care deeply about clean architecture, but I’m equally opinionated about when not to over-engineer.

Tech I Work With

While tools change, these are some I regularly use:

• Flutter, Dart
• Kotlin, Python
• FastAPI
• PostgreSQL
• Firebase (when it fits)
• AWS (Lambda, S3, CloudWatch, etc.)

I choose tools based on context and constraints, not trends.

About This Blog

This blog is intentionally minimal.

There are no pop-ups, trackers, or growth hacks.
Just long-form writing, focused on clarity and depth.

If something here helps you think differently about a problem — it has done its job.
