✅ $300K+ Earned | Top Rated Plus | 8,000+ Hours | 38 Jobs | 100% Job Success I build production-grade LLM, RAG, and AI Agent systems. Not prototypes. Not API wrappers. Real Python pipelines, deployed on AWS, handling real traffic. If your AI needs to actually work in production, let's talk. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🤖 LLM AND GENERATIVE AI ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ End-to-end LLM applications using OpenAI (GPT-4o), Claude, Gemini, LLaMA, and Mistral. Full RAG pipelines over your documents, databases, and knowledge bases. AI Agents and multi-agent workflows built on LangChain, LangGraph, and LlamaIndex. LLM fine-tuning with LoRA, QLoRA, PEFT, RLHF, and DPO on open-source models. Prompt engineering, tool calling, memory patterns, guardrails, tracing, and LLM evaluation harnesses. If your team is moving an LLM prototype to production, this is exactly where I work. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ⚡ FASTAPI AND DJANGO BACKENDS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ FastAPI and Django are my backend stack of choice for AI-powered services. → Async REST APIs: FastAPI + Pydantic + SQLAlchemy + PostgreSQL → Scalable Django backends: DRF, Celery, Redis, multi-tenant SaaS architecture → FastAPI as the serving layer for LangChain, RAG, and agent endpoints → Auth systems: JWT, OAuth2, RBAC → Microservices, Docker, Kubernetes, CI/CD via GitHub Actions and GitLab CI → Swagger / OpenAPI documentation, clean architecture, full test coverage ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🎙️ VOICE, AUDIO, VIDEO AND TEXT AI ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ → Voice AI agents and real-time speech pipelines (Whisper, AssemblyAI, Deepgram, ElevenLabs, VAPI, Retell AI) → STT / TTS integration, NLP, NER, and multimodal LLM pipelines → Computer Vision: YOLO, OpenCV, CNNs, Vision Transformers → Diffusion pipelines and image / video generation workflows → Audio transcription, classification, and processing at scale ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🧠 ML, MLOPS AND VECTOR SEARCH ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ML Stack: PyTorch, TensorFlow, HuggingFace, scikit-learn, XGBoost Vector DBs: Pinecone, Weaviate, Milvus, FAISS, pgvector, Elasticsearch Serving: vLLM, TGI-style inference, batching, caching, routing, streaming responses MLOps: MLflow, DVC, Prefect, Ray, eval harnesses, regression testing, tracing Cloud: AWS (SageMaker, EKS, EC2, Lambda, Bedrock, DynamoDB, CloudFront), Terraform, GPU providers ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🏆 WHAT MAKES ME DIFFERENT ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Most AI freelancers deliver a Jupyter notebook or a thin wrapper around an API. I architect and ship the full system. I have 14+ years of engineering experience and a background as a Fractional CTO and AI/ML Team Lead. I have led teams and personally written the code. I think in systems, delivery, and cost control, not just individual features. At Alethea AI, I was part of the team that built a cloud-native architecture on AWS capable of accommodating 30 million visitors, highlighted in an official AWS case study. The platform publicly closed a $16M token sale. That is the level of production reliability I bring to every engagement. ✔ Architecture designed for scale from day one ✔ Clean code, full documentation, and production observability ✔ I write the code myself, no offshoring your project ✔ Reliable delivery: timelines, milestones, and accountability ✔ Cost-controlled cloud and GPU workloads ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🤝 WHO I WORK WITH ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Startups validating AI-first MVPs fast. Scaleups moving LLM prototypes to production. Product teams that need a senior AI/ML engineer who can own the full stack, from fine-tuned model to FastAPI endpoint to deployed AWS service. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 📩 Message me with your current state, timeline, and constraints. If I can help, I will tell you exactly how, usually within a few hours.

Python Developer with 5+ years building production backends, web scrapers, and automation systems. I specialize in Django, FastAPI, Selenium, Scrapy, Playwright, and AI automation — delivering scalable APIs, intelligent crawlers, and bots that turn manual work into reliable, automated pipelines. ⭐ 889+ hours billed on Upwork across 19 successful projects ⭐ Backend systems handling millions of records with PostgreSQL, Redis & Docker ⭐ Data scraping for JavaScript-heavy sites and dynamic content ⭐ AI-powered automation with OpenAI, Claude, LangChain & LangGraph ⭐ Clean, tested, production-ready code 🔹 What I build for clients: - High-performance REST & async APIs with FastAPI, Django, and Flask - Web scraping & data extraction with Selenium, Scrapy, Playwright, BeautifulSoup - Automation bots for data collection, workflow, messaging, and desktop tasks - AI agents & LLM workflows with LangChain, LangGraph, OpenAI, and Claude - ETL pipelines with PostgreSQL, MySQL, Redis, and Celery - Dockerized deployments with CI/CD on AWS, Render, and DigitalOcean - Secure authentication with JWT, OAuth2, and role-based access control 🔹 Python Backend Development I design backend architectures that handle real workloads — microservices with FastAPI and Django, async PostgreSQL queries, Celery + Redis for background jobs, and RabbitMQ for distributed tasks. I build APIs that integrate cleanly with third-party services (Stripe, Twilio, OpenAI, Google APIs) and deploy them with Docker and Nginx for fault-tolerant production environments. 🔹 Web Scraping & Data Extraction I build Python scrapers that handle complex sites — dynamic React/Vue/Angular content, authenticated sessions, and public REST/GraphQL APIs. I work with both browser automation (Selenium, Playwright) and pure HTTP scrapers (Scrapy, Requests) depending on what the target source needs. Data is cleaned, validated, and delivered in CSV, JSON, Excel, or directly to your database. I only work with public data or sources you have authorization to access. 🔹 AI Automation & LLM Integration I build production-grade AI systems using LangChain, LangGraph, and Langfuse — from simple LLM workflows to multi-agent systems with tool use, memory, and state management. I integrate OpenAI, Claude, and other LLM APIs for text parsing, data enrichment, classification, summarization, and intelligent agents. I build RAG systems with vector databases (Pinecone, Chroma, pgvector), prompt pipelines, and AI-powered ETL flows that turn unstructured data into structured business insights. With Langfuse, I add full observability — tracing, evaluation, and cost monitoring for every LLM call in production. 🔹 Selected Projects - AI-Powered Job Data Pipeline — Async FastAPI ETL ingesting XML feeds, AI enrichment, syncing to external APIs via Docker - Script Marketplace Platform — FastAPI + Docker SDK platform running isolated bot containers with task scheduling and live monitoring - Browser Automation Desktop App — Tkinter-based tool with advanced Selenium logic, session handling, and modular UI - Multi-Tenant E-Commerce ERP — Django + gRPC + Stripe + PostgreSQL with real-time order tracking - Financial Intelligence Dashboard — Python Dash analytics platform for structured financial data - PyQt5 WhatsApp Automation — Desktop messaging automation with a polished GUI - HLS to RTSP Conversion API — FastAPI service for live video stream conversion 🔹 Frontend (when needed) I focus on Python backend, but I can build clean, functional UIs in React, HTML, CSS, and JavaScript when a project needs an integrated frontend — so you don't have to hire two people for one workflow. 🔹 How I work ✓ Agile development with Git, GitHub, and Jira ✓ Clear daily communication and status updates ✓ Clean, modular code with proper testing and documentation ✓ Honest timelines — I tell you what's realistic, not what you want to hear ✓ Post-delivery support and revisions included 💬 Send me a message with your project details — I respond within a few hours and I'm happy to review your requirements before you commit to anything.
