REAL AI DELIVERY. NOT JUST A BUZZWORD. Real AI delivery is different. It is knowing when RAG is the right call and when fine-tuning is. It is building LangChain pipelines that do not collapse when the context window fills. It is connecting n8n workflows to live business systems without creating a fragile mess that breaks at 2am. That is what I do. And I have been doing serious backend delivery for 25 years before AI became a buzzword. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 17 countries. $360M in cost savings. 139 clients. 100% Job Success Score. Top Rated Plus. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT I BUILD ▸ AI automation systems — LangChain, RAG, LLM orchestration, n8n ▸ Python, Django, FastAPI backends built for real traffic ▸ ERPNext and Frappe implementations, custom apps, data migrations ▸ Legacy and brownfield rescue where previous teams left things broken ▸ API integrations that survive production ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ BEFORE YOU SHORTLIST ANYONE The real question is not whether you can find someone cheaper. It is whether you can afford to get this wrong one more time. If you are sitting on a broken build, a half-finished AI system, or a codebase that scares you — that is exactly where I start.

Scrapers breaking every week? Manual processes eating 10+ hours? I build Python automation systems web scraping, AI pipelines, and n8n/Zapier workflows that run reliably without your supervision. And I build AI-enriched automation pipelines — using LLMs to classify, extract, and structure unstructured data at scale. With 24,000+ hours and 143 completed projects on Upwork, I help data-driven companies build reliable, automated data pipelines — from web scraping all the way to clean, structured data delivered into their dashboards, CRMs, and cloud platforms. Most clients come to me after dealing with fragile scrapers that break on every site update, or manual processes that eat 10+ hours per week. I fix both. What I build for you: 1- Python scrapers that handle anti-bot detection, JavaScript rendering, and high volume (10K–1M+ pages/day) 2- n8n and Zapier workflows that move data automatically between platforms with zero manual steps 3- ETL pipelines on Databricks and GCP (Bronze → Silver → Gold) with Airflow orchestration 4- Lead generation systems that collect, filter, and enrich contact data from multiple sources 5- AI-enriched pipelines that classify, summarize, and structure raw data automatically Clients I work best with: real estate platforms, B2B SaaS, e-commerce intelligence tools, recruitment tech, and growth agencies.
