AmanPrajapati
I build software that real businesses actually run on — order management systems, ERP platforms, mobile apps. Currently the solo tech lead at a food distribution company, shipping production code that goes straight to the CFO's dashboard.
Tech Stack
I don't just write code —I build software that helps businesses grow.
Every system I ship is engineered around what the business actually needs — designed to scale with real operations, not just to look good in a demo.
An architect who ships products, not just code.
Based in Mumbai, India — I take products from a blank repository to real users, owning architecture, infrastructure, security and AI integration.
I build production-grade systems, enterprise platforms, AI integrations and scalable architectures.

The Journey
BSc Computer Science
The fundamentals — algorithms, systems, the why beneath the what.
MCA
Master of Computer Applications — depth in software engineering.
Mobile Application Developer
Shipping Flutter apps to the Play Store and App Store.
Full Stack Engineer
Owning the stack end-to-end — frontend to database to deploy.
Enterprise Product Builder
Architecting production platforms that run real businesses.
AI Systems Engineer
Embedding Gemini, vector search and AI workflows into products.
A production-grade enterprise platform, built from scratch.
Designed and developed end-to-end — the operational backbone running orders, warehouse, credit, logistics, quality and sales for a real business, in production.
This is what I'm building right now — I own BigSams end-to-end in production and drive the roadmap in direct conversation with company leadership, shipping the features the business actually needs. I scope, architect, build, deploy — and present the engineering ROI to the CFO myself.

Systems, not scripts.
The mental models behind every product I build — architecture decisions made before the first line of code.
Scalable Backend Architecture
Modular, middleware-driven services that grow without rewrites.
Realtime Systems
Socket.IO rooms streaming sub-second updates to every client.
RBAC Security Design
20+ roles, permission guards and a secure middleware chain.
Audit Logging Systems
Every state change traced — who, what, when, immutable.
Notification Engines
FCM push, web push and email across one unified pipeline.
AI Systems
Gemini risk scoring, embeddings and RAG-style retrieval.
Cloud Infrastructure
Nginx, PM2 and SSL on DigitalOcean — Prod & UAT environments.
Data Pipelines
Aggregation pipelines, indexing and optimized query design.
I architect the system. AI accelerates the build.
This is how senior engineers build today — leverage over grunt work. The system design, data models, business logic and integration are mine. AI writes implementation under precise direction, and nothing ships without my review, tests and benchmarks.

AI is the typewriter — not the author.The architecture, the business logic, the review and the production ownership are all mine. Every algorithm is proven and unit-tested before it ships.
