Signzy \| Building Robust High Performance Scalable Systems \| Node\.js \| Golang \| Typescript \| Java ## About Software Engineer with 4 years of experience turning fintech backend infrastructure into fast, secure, and self\-healing systems — from IC to leading a 5\-engineer team\. At Signzy, I led development of a microservices\-based KYC platform from scratch \(LoopBack, MongoDB, RabbitMQ\), lifting KYC completion rates to 98% and cutting onboarding time by 70%\. When vendor failures were killing reliability, I engineered an auto\-retry mechanism that took success rates from 80% to 98%\+ — no manual intervention needed\. Now at iCrimeFighter, I've shifted focus to security: identified and remediated 15\+ vulnerabilities across a platform serving 950\+ agencies, closed JWT session leaks across 20\+ APIs, and built zip\-bomb detection for evidence file uploads with zero false positives\. I build for scale in my own time too — a distributed task queue in Node\.js/TypeScript handling 1000\+ jobs/sec at sub\-second latency with 99\.9% completion, and a Java\-based matching engine load\-tested at 100,000 concurrent orders with zero race\-condition failures\. Stack: Node\.js, TypeScript, Java \| LoopBack, Express, Fastify \| MongoDB, PostgreSQL, Redis, Elasticsearch \| RabbitMQ, Docker, Kubernetes, Terraform Outside of engineering, I'm a state\-level table tennis medalist — same instinct for reading pressure and reacting fast applies to production incidents\. Open to backend/distributed systems roles — let's talk if you're building something that needs to scale over a virtual coffee ☕ ## Location Gurgaon ## AI stack claude code claude github copilot ollama openai ## Work experience Software Engineer at iCrimeFighter, Feb 2026 \- Jul 2026 · 5 mo, Remote, • Identified and remediated 15\+ security vulnerabilities for 950\+ agencies across the platform as part of a product security audit, covering access control, authentication, and infrastructure hardening • Implemented zip bomb detection for the evidence file viewer using Central Directory analysis, blocking malicious archive uploads with 0 false positives • Fixed JWT session token leakage across 20\+ APIs, implemented missing CSP headers for a new product feature, and enforced CORS policy across 6 domains eliminating unsafe script execution and subdomain spoofing risks Software Development Engineer II at Signzy, Sep 2025 \- Mar 2026 · 6 mo, Hybrid, • Led the development of a microservices\-based KYC system from scratch using LoopBack, MongoDB, and RabbitMQ, managing a team of 5 developers\. • Architected a dynamic microservice API workflow to auto\-select the optimal KYC route as per SEBI guidelines, improving KYC completion rate to 98%\. • Engineered an auto\-retry mechanism for vendor failures using RabbitMQ queues, reduced failure rate from 20% to \~2%, removed manual intervention and increasing system resilience\. • Designed a SEBI\-compliant KYC workflow that reuses data to route eligible users through a 70% faster onboarding journey\.
