Python and AI engineer with over 6 years of experience developing production systems across the full stack, from backend to frontend, incorporating LLM and automation layers that add value. I have built trading platforms with real-time data feeds, RAG pipelines based on internal documents, workflow automation replacing manual tasks, and full-stack applications drawn from scratch and deployed to production. TOP RATED - 100% JOB SUCCESS - 100+ PROJECTS DELIVERED WHAT I BUILD AI systems that work in production rather than in demos: RAG pipelines that retrieve accurately from your own data, AI agents automating real business processes, and LLM integrations built to reduce cost rather than inflate it. Alongside the AI layer: full-stack applications with Python backends and React or Next.js frontends, REST APIs in Django or FastAPI, real-time features via WebSockets, cloud deployments on AWS, Azure, or GCP, CI/CD pipelines, and complex third-party integrations. THE STACK - AI/LLM: GPT, Claude, Gemini, LangChain, LlamaIndex, RAG Pipelines, AI Agents, pgvector, Pinecone - Backend: Django, DRF, FastAPI, Flask, Celery, AsyncIO, WebSockets - Frontend: React, Next.js (App Router), TypeScript, Tailwind CSS, shadcn/ui - Databases: PostgreSQL, MySQL, MongoDB, Redis, Elasticsearch, Supabase, Neon - DevOps: AWS, GCP, Azure, Docker, Kubernetes, Nginx, GitHub Actions - Linux: Ubuntu, Debian, CentOS, VPS, SSL, Supervisor, Systemd RESULTS - Reduced GPT inference costs through a custom RAG architecture that eliminated redundant API calls without accuracy loss - Cut API latency significantly through async redesign with FastAPI and Redis - Processed millions of events daily at low latency on containerized infrastructure - Migrated a Django monolith to microservices without taking the system offline - Compressed release cycles from days to hours through CI/CD automation - Reduced monthly cloud spend through infrastructure rightsizing on AWS and GCP LET'S TALK If you need backend, frontend, AI integration, and cloud deployment done properly the first time, that is what I do.
