Java backend engineer working through:
Java → Spring Boot → Backend Architecture → Databases → Security → System Design → Scalable Software
I build full-stack systems end to end and explore applied AI/ML, RAG, and LLM-backed applications alongside that core direction.
I care about systems that remain correct under concurrency, retries, duplicate requests, out-of-order events, and partial failures — not just systems that work on the happy path.
DSA → OOP → Databases → Backend Development → Spring Boot → Security → System Design → Scalable Systems
Currently going deeper into:
- ☕ Java & Spring Boot
- 🏗️ Backend architecture & modular monoliths
- 🗄️ Database design & transaction correctness
- 🔐 Authentication & authorization
- 🌐 REST API design
- 📐 System design & scalable software
- 🤖 Applied AI/ML, RAG & LLM applications
This is an active engineering direction, not a claim of mastery.
Enterprise ERP · Java 21 · Spring Boot · React · TypeScript · MySQL
A modular ERP system built for Spidosoft Technologies OPC Pvt. Ltd., centered around a single source of truth for master data.
Role: Architecture & Backend Lead
- Modular-monolith architecture
- Master-data architecture for items, customers and suppliers
- Java 21 + Spring Boot backend
- JWT authentication
- Role-based access control
- React + TypeScript frontend
- MySQL persistence
- REST API architecture
The frontend foundation and deployed landing experience are live. The backend and core modules are currently in active development.
Custom Print Commerce · NestJS · Prisma · PostgreSQL
A commerce platform for custom printing designed around database-enforced correctness.
- Transactional checkout
PaymentAttemptuniqueness guarantees- Idempotent payment webhook handling
- PostgreSQL transactional outbox
- JWT rotation
- Session revocation
- Prisma relational data model
- Modular backend architecture
The architecture is designed to remain correct under double-clicks, retries, duplicate webhooks, and partial failures.
Backend infrastructure and architecture are implemented. Business services are still in development, and Razorpay integration is designed but not yet wired.
Smart Kopargaon Hackathon 2026 · PS014 · Team FaultLine
An offline-first parcel delivery architecture/prototype built around existing public bus routes.
- React Native mobile client
- WatermelonDB + SQLite local persistence
- Offline-first architecture
- Idempotent synchronization
- NestJS backend
- PostgreSQL + PostGIS
- Sender / Conductor / Recipient / Admin roles
- Signed, nonce-based, time-bound handover verification
The handover mechanism is designed to be verified on-device, allowing the workflow to continue even when connectivity is unavailable at the handover point.
Focus: Offline synchronization · event ordering · security · unreliable connectivity
Hackathon prototype — not a production system.
