Why I choose NestJS for scalable SaaS backends
When building for scale, a simple Express setup often isn't enough. As projects grow, they need structure. In my recent work, I’ve been heavily relying on NestJS to build event-driven systems.
Why?
Dependency Injection: Makes testing (with Jest/Playwright) much smoother.
Modular Architecture: Perfect for migrating legacy monoliths to microservices.
TypeScript first: No more "undefined is not a function" at 3 AM.
If you’re planning to scale your product in 2026, don't just build features - build an architecture that lasts.

Most mobile apps don’t become hard to maintain because of scale.
They become hard to maintain because early architecture decisions were made for speed, not clarity.
At first, it works fine.
But over time:
• Business logic starts leaking into UI layers
• State becomes unpredictable across screens
• And small changes start touching unrelated parts of the app
What looked like “flexible architecture” slowly turns into invisible coupling everywhere.
This is exactly what I’ve been thinking about while building production mobile systems.
Roule.io is a multiplayer board games site. Users can play uno, monopoly, and ludo with advanced bots or with friends.
The entire backend is written in Golang and can handle 50,000 concurrent rooms at any point of time with low compute costs $35/month. The game also has multiple skins tokens and more to improve user engagement.

Wow this is impressive! Nice work!
Looking for freelance work (Backend / AI / Full-Stack)
I’m currently open to freelance projects — mainly backend-heavy systems, AI integrations, or full-stack builds.
I’m a Software Engineer working with Java (Spring Boot), Python, and SQL, and I’ve built systems that are already used in real environments (not just demos).
Some of the work I’ve done:
• Built AI-powered document processing systems (LLM + FastAPI + validation pipelines) to extract and structure data automatically
• Developed a financial AI chatbot (RAG-based) that answers queries using real documents and reduces manual workload
• Created a real-time network anomaly detector using Python (Scapy + Suricata) for monitoring suspicious traffic
• Built API integration middleware (Java Spring Boot) connecting multiple systems with retry logic and structured logging
• Developed a smart inventory system with analytics (Node.js + PostgreSQL + MongoDB) used for tracking stock and sales trends
• Implemented ETL pipelines for data migration and reporting (Python + SQL + Pandas)
• Built an automated web security scanner detecting SQLi/XSS issues before deployment
• Worked on computer vision models for defect detection and image classification (CNN + TensorFlow)
• Developed full-stack apps (Flask / FastAPI + React) with real-time API integrations
I’ve also worked in enterprise environments, handling:
production deployments
debugging live systems
API integrations across teams
working with international clients
What I usually work on:
Backend systems & APIs
AI features (chatbots, automation, document processing)
Data-heavy applications
System integrations
MVPs that need to actually scale
I’m not here to just “build features” — I focus on making systems reliable, usable, and production-ready.
If you need someone who can:
✔️ understand your system
✔️ build fast
✔️ and not break things in production
send me a message.
