New to upwork ⚡️ ENTERPRISE BACKEND & AI ARCHITECT | CLOUD COST REDUCTION (MIN 30%) | AWS ECS, BUN & FASTAPI Does your enterprise application suffer from sluggish APIs, database bottlenecks, or bloated cloud infrastructure costs? I help enterprise teams and high-growth startups cut their AWS/cloud compute costs by a minimum of 30% while making their APIs lightning-fast. With 8+ years of engineering experience, including re-architecting systems for a $2.8 Billion enterprise and building advanced AI agents for high-traffic platforms,I specialize in solving complex backend bottlenecks. I diagnose sluggish monoliths, migrate them to highly optimized microservices, and deliver rock-solid stability without sacrificing code maintainability. 💡 HOW I DELIVER IMMEDIATE VALUE: 🤖 AI AGENTS & VECTOR SEARCH (RAG): I architect intelligent discovery agents and custom AI workflows using Python (Agno), LanceDB (Vector Databases), and Gemini LLMs. I seamlessly integrate these high-volume scraping and semantic search features into internal tools and Shopify Apps via robust, low-latency APIs. 📉 CLOUD COST OPTIMIZATION (AWS ECS): I decouple resource-heavy monoliths into scalable, domain-driven microservices. By containerizing with Docker and orchestrating via AWS ECS, I eliminate compute waste and ensure your system only scales exactly when needed. ⚡ STRATEGIC CACHING (REDIS / AWS ELASTICACHE): Database queries are expensive. I implement aggressive, multi-tiered caching layers to serve high-volume API requests directly from memory. This drops latency to single-digit milliseconds and drastically scales down expensive database read-replicas. 🚄 HIGH-PERFORMANCE MIGRATIONS: I replace legacy Node.js/Express bottlenecks with ultra-fast runtimes like Bun and Elysia, or asynchronous Python frameworks like FastAPI. (Recent win: Migrated a core enterprise API, reducing response times from 5+ seconds to under 200ms). 🗄️ ADVANCED SQL TUNING: I don't just write queries; I architect data pipelines. I rewrite resource-heavy SQL, implement advanced indexing (B-Tree, GIN, GiST), and eliminate sequential scans to prevent database deadlocks under heavy load. 🏆 SELECTED ENTERPRISE WINS: • GENUINE REPLACEMENT PARTS : Engineered custom AI agents using Python (Agno), LanceDB, and Gemini for intelligent appliance part discovery on a high-traffic e-commerce platform. Built internal Shopify App APIs and automated large-scale image scraping pipelines, drastically improving semantic search accuracy and reducing manual cataloging. • STORAGE KING USA ($2.8B Enterprise): Engineered and optimized the core booking API. Migrated architecture to Bun/Elysia, implemented AWS SQS for asynchronous message queuing, and drastically reduced database overhead. • TYPO (typo.so) & MIND RETREATS: Delivered highly scalable microservice architectures. Built CI/CD auto-deployment pipelines via Bitbucket to optimize staging/production container costs globally. • QUALITY LICENSING SUPPLY : Architected a complex Assortment Management Tool (NestJs/TypeScript), designing highly efficient report-generation algorithms for massive datasets with zero latency issues. 🛠️ CORE TECHNOLOGY STACK: • Architecture & Cloud: AWS (ECS, EC2, SQS, ElastiCache), Docker, Microservices, CI/CD. • High-Performance Backend: Bun, Elysia, Python (FastAPI, Django), Node.js (NestJs, Express). • AI & Agentic Workflows: Python (Agno), Gemini LLMs, PyTorch, Custom AI Agents, Web Scraping Pipelines. • Databases & Caching: LanceDB (Vector DB), PostgreSQL, Advanced SQL Optimization, Redis, MongoDB. 🚀 LET'S FIX YOUR BACKEND BOTTLENECKS. If you are dealing with slow APIs, database crashes, looking to integrate intelligent AI agents (RAG/Vector Search), or trying to lower a bloated AWS bill, invite me to your job. Let's map out a strategy to modernize your infrastructure today.
