3+ years building with TypeScript, Node.js, Go, and Python — from microservices and event-driven architectures to LLM-powered pipelines.
Work Experience
Where I've Built
3+ years of shipping production systems for enterprise clients — from AI-powered pipelines and marketplace integrations to distributed microservices architecture.
Software Engineer
GSPANN Technologies
Designed, built, and scaled backend and full-stack systems using TypeScript, Node.js, Next.js, and Python for high-traffic enterprise platforms.
- ▸Architected an end-to-end RAG-based image compliance pipeline using LLaMA vector embeddings — reduced processing time by 82% (45 min → 8 min) across 10,000+ daily records
- ▸Engineered LLM-backed SEO content generation into a BigCommerce cron job, auto-producing descriptions and metadata across 10,000+ product records per day — contributing to a client-reported 15% uplift in sales
- ▸Designed, built, and launched a BigCommerce marketplace app as the organisation's sole BigCommerce specialist — achieved 20+ downloads within hours of release
- ▸Refactored production category taxonomy from 16,000 to ~1,900 MySQL entries by replacing per-year duplication with a dynamic year-pool model backed by server-side caching — cut page load times by 30% and eliminated a scaling bottleneck
- ▸Improved query performance measurably — confirmed by client and PM — through compound MySQL indexing, N+1 elimination, and multi-layer caching with invalidation strategies at API and browser layers
- ▸Containerised services with Docker and built CI/CD pipelines standardising release practices; maintained polyglot datastores (PostgreSQL, MySQL, MongoDB, Redis) for high-volume workloads
Teaching Assistant — Security Testing
King's College London
Delivering and facilitating hands-on postgraduate security testing lab sessions covering core offensive and defensive security concepts.
- ▸Led practical labs on SQL Injection, XSS, CSRF, client-side control bypassing, and network reconnaissance
- ▸Guided students through exploiting real-world vulnerabilities and implementing secure fixes
- ▸Demonstrated industry-standard tools including Metasploit, SET, and Maltego
- ▸Reviewed and assessed lab submissions with detailed technical feedback on vulnerability identification and remediation
Open Source
Open Source Contributions
Selected public contributions to production codebases.
Built the official Docker implementation for Provara — a cryptographically signed AI agent memory protocol
- ▸Designed minimal container setup with explicit vault mounting and env-only secret injection, preserving protocol sovereignty constraints
- ▸Iterated through maintainer review to deliver a production-ready, auditable Docker packaging solution
- ▸Authored DOCKER.md with full design rationale and updated README Quick Start documentation

View Merged PRImplemented issue-density normalisation to make scoring penalties proportional to codebase size
- ▸Proposed a penalty-scaling formula so a single security finding in a small clean codebase scores proportionally rather than causing a disproportionate penalty drop
- ▸Contribution incorporated into the v0.1.2 release of aislop — a CLI tool that detects AI-generated code quality patterns across TypeScript, Go, Python, and more

Systems I've Built
Each project is an interactive system — click architecture nodes to inspect components, explore engineering decisions, and trace data flows. These case studies show real engineering with clear, transparent tradeoffs.

Education
Academic Foundation
From a CS bachelor's in India to an MSc at King's College London — continuous investment in depth and breadth of engineering knowledge.
MSc Advanced Software Engineering
King's College London
Pursuing a Master's in Advanced Software Engineering with practical focus on building scalable distributed systems, applying security testing methodologies, and designing production-grade software architectures.
- Teaching Assistant for Security Testing — leading postgraduate lab sessions and mentoring students on secure coding and vulnerability assessment techniques
- Dissertation research on AI-enhanced concept navigation and forum assistance for blended Computer Science education — combining NLP, knowledge graphs, and LLM-based retrieval to improve how students navigate course materials.
- Hands-on application of security, software architecture, and system design principles through advanced coursework
Key Coursework
B.Tech Computer Science
