BUILDING DIGITAL
PRODUCTS THAT
SOLVE REAL PROBLEMS.
Hi, I'm Tanuj Kashyap — Software Developer crafting scalable backends and modern web platforms.
THE HUMAN //
BEHIND THE CODE.
Specialized in Java, Spring Boot microservices, secure JWT authentication, and relational query optimization. I build systems that perform reliably under high concurrency.
I am a Java Backend Developer with 1+ year of professional experience specializing in engineering scalable REST APIs, microservices, and secure backend systems using Spring Boot. With industry experience designing production workflows at DSD Systems Pvt Ltd, I prioritize clean layered architecture, performance, and high availability.
My technical core spans Spring Security (JWT & RBAC), JPA/Hibernate, global exception handling, and database query optimization across PostgreSQL and MySQL. I have architected high-throughput systems—including a Porter-like logistics platform leveraging Redis broadcasting to reduce database load by over 90%, and a multi-tenant SaaS salon management platform.
I hold an MCA in Computer Science from Delhi Skill and Entrepreneurship University and a BCA from Institute of Technology and Science. I focus on writing maintainable, production-ready code that drives real business impact.
ENGINEERED FOR PRODUCTION.
Real-world backend architectures, scalable microservices, and client platforms engineered with technical rigor and verified in production.
Logistics Platform (Porter-like App)
High-frequency Redis driver broadcast, real-time routing, Razorpay wallet & notification engine
- Reduced database read/write pressure by over 90% via Redis in-memory location caching.
- Instantaneous sub-15ms nearby driver lookup and broadcast dispatch.
- 100% financial transaction accuracy across driver wallet recharges and payouts.
Salon Platform (Multi-Tenant SaaS)
Multi-store management, staff commission tracking, PostGIS geolocation, booking engine & notification service
- 100% role-based security isolation across multi-store manager and staff tiers.
- Sub-25ms response time for advance slot booking and availability checks.
- Automated Notification Service for instant booking and schedule reminders.
TECHNOLOGY ECOSYSTEM.
Connected architectural nodes linking the core system engine to supporting production technologies.

Primary Backend EngineHOW I BUILD.
Guiding architectural principles that ensure software is maintainable, fault-tolerant, and delivers tangible business value.
THINK IN SYSTEMS
Architecture, maintainability, and scalability over quick hacks.
Every feature is part of a larger ecosystem. I architect with clear domain boundaries, strict API contracts, and predictable data flows so systems stay easy to reason about as traffic grows.
BUILD FOR REAL USERS
Features must solve actual business problems, not just demonstrate technology.
Technical sophistication is meaningless if the end user experiences friction. I focus on sub-100ms response times, intuitive state management, and reliable error handling.
KEEP IT SIMPLE & MODULAR
Complex systems should have simple interfaces and clear abstractions.
Premature complexity is the enemy of velocity. I prefer well-tested, decoupled components and battle-tested patterns over unnecessary layers of abstraction.
SHIP, MEASURE & ITERATE
Build, automate tests, deploy securely, and continually refine.
Continuous delivery and observability are first-class citizens. Automated pipelines, structured logging, and fast feedback loops ensure reliable releases.
