I build AI systems that work in production - not just in demos.
With 10+ years in AI/ML and enterprise software, 3000+ hours on Upwork, 700+ solutions delivered, and 400+ clients across the globe, I've earned a simple reputation: if you need intelligent automation, a custom LLM application, or a scalable ML pipeline, I'll build it, ship it, and make sure it holds up.
I work across the full AI stack: from raw data ingestion and model training to fine-tuning LLMs, deploying RAG architectures, and integrating everything into production-grade systems. Whether the project lives on AWS (Bedrock, SageMaker, Textract, Comprehend), Google Cloud (Vertex AI), or runs locally (Ollama, LLaMA, DeepSeek), I build for the environment that fits your business, not the one that's easiest for me.

𝗪𝗵𝘆 𝗰𝗹𝗶𝗲𝗻𝘁𝘀 𝗰𝗼𝗺𝗲 𝗯𝗮𝗰𝗸
Most AI projects fail at the handoff from prototype to production. I've spent a decade closing that gap, writing systems that are maintainable, monitored, and built to scale beyond the first deployment.
- Production-first architecture from day one
- Strong documentation and clean, handoff-ready code
- Experience across AWS, Azure, GCP, and open-source stacks
- Clear communication throughout, no black boxes
- On-time delivery with post-launch accountability
𝗘𝘃𝗲𝗿𝘆 𝗽𝗿𝗼𝗷𝗲𝗰𝘁 𝗶𝗻𝗰𝗹𝘂𝗱𝗲𝘀:

AI Automation & Python Engineer — production AI agents, browser automation, RAG systems, data extraction pipelines, and backend applications that solve real business workflows.
I build production-ready automation and AI systems, not just prototypes.
My work combines Python, Playwright, FastAPI, OpenAI/Claude/Gemini, RAG, n8n, APIs, databases, and cloud infrastructure to automate workflows that would otherwise require hours of repetitive manual work.
I have 8+ years of experience with Python, web scraping, browser automation, APIs, data processing, and backend development, and I now specialize heavily in AI-powered automation.
WHAT I BUILD
→ AI Agents & Business Automation
AI agents that can research, extract data, process documents, make decisions, call APIs, update databases, generate reports, and trigger downstream workflows.
Tech includes OpenAI, Claude, Gemini, n8n, Make, Python, FastAPI, MCP, structured outputs, tool calling, and custom APIs.
→ RAG & Knowledge-Base Chatbots
Production RAG systems that answer questions from private company documents and knowledge bases.
Typical architecture:
Documents → Parsing → Chunking → Embeddings → Vector Database → Retrieval → LLM → Citations
I work with FAISS, pgvector, Supabase/PostgreSQL, OpenAI embeddings, Claude, Gemini, and custom retrieval pipelines.
→ Browser Automation & Web Scraping
Complex automation for authenticated portals, dashboards, document downloads, data collection, and repetitive browser workflows.
I work extensively with:
Playwright • Selenium • Scrapy • requests • aiohttp • BeautifulSoup • lxml
Including dynamic JavaScript websites, pagination, authenticated sessions, downloads, retries, proxy infrastructure, and anti-bot environments.
→ Document & PDF Automation
Systems that turn PDFs, receipts, statements, images, spreadsheets, and business documents into structured data.
Examples include:
PDF/Image → OCR/Vision → Extraction → Validation → Structured JSON/CSV/Excel → Database/API
I build workflows for invoices, receipts, financial documents, reports, forms, and large document collections.
→ Python / FastAPI Backend Systems
Production APIs and backend services using:
Python • FastAPI • Django • Flask • Celery • Redis • PostgreSQL • MySQL • MongoDB • Docker
I can own the complete backend — API design, asynchronous processing, database architecture, background jobs, integrations, logging, testing, and deployment.
→ n8n / Make / API Automation
I automate workflows across CRMs, Google Sheets, Google Drive, email, databases, AI models, internal APIs, and third-party SaaS platforms.
When low-code is enough, I use it.
When reliability or complexity requires code, I build the missing pieces in Python.
RECENT SYSTEMS I’VE BUILT
AI Healthcare Research Platform
Built a complete pipeline for collecting public patient discussions, extracting symptoms, interventions and outcomes with AI, normalizing thousands of signals, maintaining source-level traceability, and presenting the results through an interactive dashboard.
Bank Document Automation
Built Python + Playwright workflows for authenticated financial portals where the user handles login/MFA and automation takes over afterward — discovering accounts, downloading historical PDFs, organizing documents, detecting duplicates, and maintaining audit manifests.
AI Document Extraction Platform
Built systems that accept PDF, Excel and image documents, extract structured information using traditional parsing + OCR/Vision/LLMs, validate the results, and export clean datasets.
Large-Scale Web Data Pipelines
Built and maintained scraping infrastructure across hundreds of websites with proxy rotation, retry chains, anti-bot handling, automated QA, structured extraction, and production monitoring.
AI-Powered Data & Reporting Systems
Built structured datasets and semantic layers designed specifically for LLM reasoning, reporting, search, and downstream AI applications.

WHY CLIENTS HIRE ME

Retry and recovery strategies
Structured logging
Duplicate prevention
Validation and QA
Error reporting
Maintainable code
Human-in-the-loop workflows where appropriate
