About Me

Engineering where
scale meets craft

I'm a Full Stack MERN developer with 3+ years shipping production systems — from fintech KYC automation at Aeon Loan Services to self-engineering a LeetCode-grade coding judge platform entirely from scratch.

At Novac Technology Solutions, I owned the entire KYC module: Aadhaar, PAN, and DigiLocker verification flows, a root-cause analysis initiative that cut recurring production incidents by 30%, and Git workflow standards that eliminated architectural drift.

Outside the day job I'm building SoloDev — a gamified coding judge with sandboxed multi-language execution, 8-strategy testcase evaluation, dungeon XP progression, and JWT + RBAC authentication.

Currently expanding into AWS cloud-native architecture, targeting the Developer Associate certification while deploying real MERN infrastructure on EC2, S3, CloudFront, and Lambda.

⚙️
Systems Thinker
Architecture before code. Feature-module separation, API layer abstraction, and zero-downtime rollout are baked into every project.
🎯
Production-Obsessed
Zero hotfixes after launch isn't luck — it's disciplined validation, error boundaries, and exhaustive edge-case coverage before shipping.
🚀
Always Shipping
SoloDev exists because I build personal projects to production standards. RTK Query cache management, RBAC, Framer Motion — not for portfolio points, but for craft.

Where I've shipped

Production fintech systems, enterprise SPAs, and component architecture — real constraints, real impact.

Jan 2024 – Present
FINTECH · LOAN SERVICING · KYC AUTOMATION
  • Owned the KYC module end-to-end as sole engineer — automated identity verification across Aadhaar, PAN, and DigiLocker, eliminating the manual review queue entirely.
  • Architected a multi-step verification UI in React + Tailwind with live verification indicators, document upload flows, and field-level validation — deployed with zero post-launch hotfixes.
  • Led a root-cause analysis initiative that identified systemic bugs platform-wide — achieved 30% reduction in recurring production incidents.
  • Introduced Git PR workflow standards and peer review gates, eliminating architectural drift and reducing merge conflict resolution time to near-zero.

ENTERPRISE SPAs · REST INTEGRATION · COMPONENT SYSTEMS
  • Delivered pixel-perfect React SPAs with Redux Toolkit across 3 client products — all matched 1:1 to Figma specs with zero QA-flagged visual regressions at launch.
  • Designed RESTful API integration layers with optimized request batching and response caching — reducing page load times and improving perceived performance.
  • Engineered a shared component library adopted across the entire engineering team, standardising design patterns and cutting feature development cycle time.
  • Implemented error boundaries and structured debugging workflows that reduced mean time-to-resolution, directly improving sprint velocity.

SOLODEV
FULL STACK CODING JUDGE PLATFORM
SoloDev Production-Grade Self-Engineered

A LeetCode-equivalent coding judge built entirely from scratch — featuring multi-language sandboxed code execution, an 8-strategy testcase evaluation engine, gamified XP and dungeon progression systems, and a fully secured JWT + RBAC multi-role authentication architecture. Every layer — from the execution engine to the animated React frontend — was engineered with zero compromises on architecture quality.

Dungeon XP System
Gamified progression with dungeon rooms, XP tracking, and skill trees wired to real API endpoints via RTK Query typed cache tags.
🏗️
Backend Architecture
Node.js/Express with clean feature-module separation across auth, submissions, challenges, and dungeon — designed for zero-downtime rollout.

Cloud Journey

Learning AWS

Actively expanding into cloud-native architecture — building real MERN deployments end-to-end on AWS infrastructure. Not studying for a badge — shipping systems with genuine security, networking, and scaling configurations.

EC2 provisioning, S3 static hosting with CloudFront CDN, Lambda serverless functions, IAM roles and policies, RDS/DocumentDB, VPC networking — all hands-on, all wired to real applications.

AWS Certified Developer – AssociateActively deploying cloud-native MERN infrastructure in parallel — EC2, S3, Lambda, RDS, VPC.
🖥️
EC2
Instance provisioning, security groups, SSH access, deployment pipelines.
S3 + CloudFront
Static hosting, CDN distribution, cache invalidation, CORS configs.
λ
Lambda
Serverless functions, event-driven architecture, API Gateway integration.
IAM
Roles, policies, least-privilege access control, service permissions.
RDS / DocumentDB
Managed database provisioning, connection pooling, backup strategies.
VPC + CloudWatch
