I am a Full-Stack Distributed Systems & AI Infrastructure Engineer with 8+ months of commercial production experience building multi-repository enterprise platforms, zero-egress cloud storage engines, and autonomous LLM agentic pipelines.

• 🏛️ Commercial Production Engineering (Harigurus — 8 Months): Sole-architected a Next.js SSR e-commerce storefront (harigurus-shop — 100% commit ownership), migrated a 20,170-LOC production React platform (harigurus.com) from static data to Sanity.io Headless CMS via GROQ queries, and contributed to the multi-stage SMS OTP checkout & Express/MongoDB production backend (harigurusBackend).
• ⚡ Distributed Zero-Egress Cloud Storage (yourvaultstorage.com): Architected Direct-to-S3 multipart streaming engines on AWS EC2 (Express 5 PM2 Cluster) + S3/CloudFront, routing Backblaze B2 streams through a Cloudflare Worker Edge CDN for $0 egress bandwidth.
• 🤖 Autonomous Agentic Systems & MCP Servers: Engineered an end-to-end customer support triage pipeline that clusters semantically identical feature requests, raises GitHub Issues at threshold $N_1$, dispatches HMAC-SHA256 signed one-click webhook emails at threshold $N_2$, and triggers a headless Codex Agent to implement code, run unit tests, and open verified Pull Requests.
• 🛡️ Granular RBAC, Security & Self-Hosted CI/CD: Implemented Redis token-bucket rate limiters, Argon2id hashing, RFC 6238 TOTP 2FA, and a custom GitHub Webhook CI/CD build runner (deploy-full.sh) with mutex lock protection.

Engineered core systems across a 3-repository commercial production ecosystem (harigurus, harigurus-shop, harigurusBackend):

• Sole-Architected E-Commerce Storefront (harigurus-shop — 100% Commit Ownership): Built Harigurus's dedicated Server-Side Rendered (SSR) e-commerce storefront from scratch across 63 files using Next.js getServerSideProps, Sanity.io CMS, Material-UI v5, and TailwindCSS with dynamic slug routing and Intl INR localization.
• Headless CMS Architecture Migration (harigurus.com): Replaced 670+ lines of hardcoded ceremony definitions in the 20,170-LOC core platform with a dynamic Sanity.io Headless CMS studio (services.js, serviceitem.js) and live GROQ queries, enabling non-technical staff to publish ceremony packages in real time with zero engineering redeployments.
• Multi-Stage OTP Checkout & Production DB Cutover (harigurusBackend): Contributed to the 940-line checkout state machine and Express/MongoDB REST API featuring Indian mobile validation, Fast2SMS & Twilio 4-digit OTP verification, JWT session persistence, and PhonePe QR payments; executed the production MongoDB database cutover.

Enterprise-grade distributed storage platform engineered for zero-egress cloud streaming, high-concurrency transfers, and self-hosted CI/CD automation.

• Zero-Egress Multi-Cloud Streaming: Hosted React 19 on AWS S3 + CloudFront (ACM SSL) and Express 5 on AWS EC2 (PM2 cluster + Nginx unbuffered proxy); routed Backblaze B2 S3 streams through a Cloudflare Worker Edge CDN for $0 egress fees.
• Throttling, RBAC & Media Workers: Distributed Redis token-bucket rate limiters, Argon2id, TOTP 2FA, hierarchical Owner/Editor/Viewer RBAC, Razorpay webhook quotas, and background libuv worker threads for Sharp WebP & FFmpeg transcoding.
• Custom Webhook CI/CD Engine: Self-hosted deployment runner (deploy-full.sh) with mutex lock protection (isDeploying), automated test verification, S3 sync, CloudFront invalidation, and zero-downtime PM2 reloads.

Event-driven autonomous triage and code-synthesis pipeline connecting customer support streams directly to verified GitHub Pull Requests.

• Semantic Ticket Clustering & Issue Escalation: Computes TF-IDF Cosine Similarity across incoming customer requests, automatically opening structured GitHub Issues once cluster demand crosses threshold $N_1$.
• HMAC-SHA256 One-Click Email Webhook $\rightarrow$ Codex PR: Dispatches cryptographically signed alert emails to engineering leads at threshold $N_2$; clicking the link triggers a headless Codex Agent (protected against replay attacks via one-time nonces) that checks out a feature branch, writes the code + unit tests, runs verification suites, and opens a GitHub Pull Request.
• MCP File Reorganization Server: Includes a JSON-RPC 2.0 Model Context Protocol server that classifies and reorganizes workspace directories with atomic transaction rollback.
