Hi, I'm Yash — I build full-stack products that scale and feel good to use.
A backend-leaning full-stack engineer with 5+ years turning messy problems into clean, fast systems — secure Node.js & Python services on AWS, paired with thoughtful React & Next.js frontends.
How I think about software
I like building things that are correct and fast on the inside, and clear and calm on the outside.
Over five years I've taken multi-tenant SaaS platforms from 0→1, designed event-driven microservices on AWS, and hardened APIs against real-world VAPT findings. I lead squads, mentor engineers, and run the backend interview loop — but I'm happiest deep in a system, making it simpler.
I'm backend-first, but full-stack by choice. I care about the React and Next.js layer just as much, because reliability and a good experience are the same promise from two directions — and the details on both sides are what make software feel trustworthy.

Ways to work together
Backend & APIs
Scalable microservices, clean REST design, DDD, and data models that don't fall over under load.
Cloud & DevOps
Event-driven AWS (Lambda, SQS, DynamoDB, CDK), CI/CD pipelines, and observability you can trust.
Full-stack delivery
React & Next.js frontends wired to robust backends — end-to-end features, not just endpoints.
Security & hardening
OWASP-aligned reviews, rate limiting, auth (JWT/OAuth2/RBAC), and resolving VAPT findings.

Where I've worked
NetWeb Software
↗ Promoted- Lead a 6-engineer squad within a 30-engineer team, owning integration microservices end-to-end and delivering a zero-rollback alpha across 5 sprint cycles.
- Built the event-driven integration layer for a multi-tenant school-district platform on SQS + Lambda + DynamoDB, processing 10,000+ record bursts with strict per-tenant isolation.
- Improved backend performance 60% via query refactoring and call batching; drove Pytest coverage past 90% and reviewed 160+ PRs across 3 squads.
- Architected modular DDD services and standardised contracts across 100+ API endpoints, eliminating cross-team versioning conflicts.
- Hardened APIs with OWASP-aligned controls — 7 security headers, rate limiting, validation — and resolved all VAPT-flagged vulnerabilities.
- Built structured CloudWatch log aggregation across microservices, cutting mean-time-to-identify on production incidents.
JKL Infotech
- Built a multi-tenant SaaS accounting platform 0→1 with database-per-tenant isolation, enabling a successful alpha launch.
- Cut API response time 70% under a TDD microservices architecture while maintaining 90%+ Jest coverage.
- Implemented a JWT/OAuth2/RBAC framework across 16 modules and automated CI/CD with Docker + Jenkins.
Deepcoder
- Created a real-time navigation platform serving 370+ test centres with high-availability route-generation APIs.
- Reduced average API response time from 5s to 0.5s (90%) using Redis caching, query optimisation, and pagination.
- Integrated a secure, webhook-driven payment gateway supporting end-to-end booking flows.
Arishti Info Labs
↗ Promoted- Co-invented an Over-The-Air update management system for IoT devices on local networks (patent pending).
- Designed secure Node.js REST APIs for authentication, file handling, and multi-device firmware orchestration.
- Drafted the provisional patent for the OTA update mechanism and researched IoT device security challenges.
An Update Management System for IoT Devices and Method Thereof
Co-inventor on a patent application for an Over-The-Air (OTA) update management system enabling secure, orchestrated firmware delivery across heterogeneous IoT devices within local networks.
