Shashi ShuklaI build, ship & scale.
Full-stack engineer — from responsive UIs to REST APIs, from Docker containers to Kubernetes clusters, from databases to AI pipelines.
README.md
Full Stack Developer with 3+ years of experience building and shipping web applications end-to-end — frontends, backends, and the infrastructure that ties them together.
Lately I've been diving deeper into the AI/ML space, exploring how to leverage data and LLMs to build smarter, more useful products.
Available for freelance — I can get your website or app built and shipped on a timeline that works for you.
Always learning, always building.
Work Experience
SDE-1 @ NFThing
July 2025 — Present- Built ELK stack powering personalized feeds across 1M+ posts — DB ingestion, filtering, ES indexing, and vector similarity with user vectors, cutting search latency by ~60% and lifting feed relevance for daily active users.
- Designed a cascade AI pipeline for response categorization (regex → KB search → LLM fallback → MiniLM cosine similarity), reducing LLM API spend by ~70% while maintaining categorization accuracy.
- Developed an MCP server for end-to-end campaign lifecycle management.
- Built a reusable push notification system for Next.js PWAs, usable across backend services.
Software Development Intern @ Hewlett Packard Enterprises
Feb 2025 — Aug 2025- Migrated the CloudCop tool from Ruby on Rails to Java Spring Boot + HTMX, improving response times by ~40% and unblocking internal teams from legacy Ruby maintenance overhead.
- Dockerized the entire application and configured a robust CI/CD pipeline, cutting deployment time from hours to minutes and eliminating versioning issues across environments.
- Redesigned the UI/UX with HTMX and added features for VM instance management, improving usability for internal developer teams.
- Implemented Wasm integration via the Wasmoon library for client-side execution of Lua scripts, reducing execution latency by ~50% and significantly lowering backend server load.
- Extended the Lua Decoder module to support test case execution, enabling client-side validation of Lua scripts.
- Collaborated on a React.js-based developer portal, resolving bugs and improving the interface used by clients to deploy Lua script-based applications.
Founding Engineer @ Greyside
Oct 2024 — Feb 2025- Built the company's flagship mobile-first personalized news PWA from scratch using Vite + React.js and Node.js, shipping the MVP in under 3 months.
- Shipped concise, point-wise news summaries and in-app learning tools, improving average session time and user retention on early cohorts.
- Designed complex UI/UX components including an interactive news timeline, precisely matching Figma design specifications.
- Integrated the OpenAI API for automated news image generation and used n8n to streamline posting workflows, cutting manual content-ops effort by ~80%.
- Configured a CI/CD pipeline to automate server deployment, reducing release cycles from days to hours and improving deployment consistency.
- Led a cross-functional team of 5 developers — sprint planning, task allocation, and on-time delivery across every milestone in the founding roadmap.
Software Development Intern @ Web3Onwards
Sep 2023 — Jan 2025- Managed server infrastructure for frontend and backend applications on DigitalOcean droplets, maintaining high uptime across production deployments.
- Built and deployed a personalized mail server using iRedMail, onboarding 100+ students and eliminating reliance on third-party mail providers.
- Developed a smart contract for minting tokens linked to movie reviews, enhancing transparency and security in the review process.
Featured Work
AI Cascade Pipeline
Cost-effective free-text response categorization using a 3-tier cascade. A rule-based filter catches gibberish for free, then a pgvector + MiniLM knowledge-base cache (cosine sim ≥ 0.80) short-circuits any response semantically close to one already classified — only genuinely novel responses reach GPT. Every GPT classification is embedded and written back to the KB, so the cache grows itself and the LLM hit-rate decays over time. A second MiniLM pass (sim ≥ 0.78) merges new categories into existing buckets to prevent duplicates, with a per-question category cap.
- ●71% LLM cost reduction measured across 23.3k production classifications
- ●Self-growing pgvector KB does 65% of the work — regex 6%
- ●MiniLM (0.78) bucket dedup + alias table prevent category drift
Projects
Chicken Cross
Solana blockchain game inspired by Mission Uncrossable that rewards players with SOL based on gameplay. Built a provably fair system using cryptographic techniques for trustless outcomes, dynamic chicken/car/collision animations, REST APIs for multi-level gameplay and sessions, and WebSockets for live score updates on a UI dashboard.
Lucky Dog Raffle
Decentralized raffle platform on Ethereum where users create, manage, and join time-bound and ticket-bound raffles with automated prize distribution via smart contracts. Built a Telegram bot using Telegraf to streamline ticket purchases, raffle creation, and prize payouts directly from chat.
