I spent the last two years as the only developer on a B2B marketing SaaS. FastAPI backend, React frontend, Stripe billing, and an AWS pipeline that rendered and personalised thousands of outreach videos.
Before that I did Python automation and scraping for clients, and for the last three years a good part of my work has been wiring LLMs into products that people actually pay to use. So I can usually tell you early whether an AI idea is worth building, or whether it is going to cost you a
lot of money to find out it doesn't work.
What I take on:
- Web apps and SaaS products, built from scratch or picked up when the last developer left them in a mess.
- LLM and AI features that have to hold up in production, not just in a demo.
- Automations, bots, and internal tools that replace something you are doing by hand right now.
- Scraping and data collection, handed back structured and ready to use.
I would rather tell you an idea is a bad one than take your money building it. If you have something in mind, send me the details and I will tell you straight whether I can do it, how I would go about it, and what it takes.

⭐⭐⭐⭐⭐ I build AI agents that do real work, answering customers, booking calls, and closing the loop, so your team stops doing it manually. 🏆 Top Rated Plus | 100% Job Success | 15+ Years Experience | 80% Long-Term Repeat Clients | [X]+ AI agents & bots shipped
🚀 **Why Businesses Trust Me**
After 15+ years delivering software and a 100% Job Success record on Upwork, I know that an AI agent is only valuable if it's reliable in production, not a demo that breaks on the first edge case. I build AI assistants and AI voice bots that handle real conversations, plug into your existing tools through n8n and Zapier, and keep running after launch.
I operate founder-minded with fast prototypes, transparent weekly updates, and a business-first focus on the outcome you actually care about. That means fewer manual hours, faster response times, and more booked revenue.
🚀 **What I Do**
I'm an AI Agent Developer specializing in AI Assistants, AI Voice Bots, and RAG-powered automation. My core areas:
1. AI Agent Development. Autonomous agents that reason, call tools, and complete multi-step tasks instead of following a rigid script.
2. AI Assistants & Chatbots. Customer-support, lead-qualification, and internal knowledge assistants trained on your data.
3. AI Voice Bots. Inbound and outbound voice agents that book appointments, qualify leads, and handle calls 24/7.
4. RAG & Workflow Automation. Knowledge-grounded answers and end-to-end automations wired into the apps you already use.
🚀 **AI Assistants & Chatbots**
🔹 RAG-powered support bots, trained on your docs, tickets, and chat history, with accurate source-grounded answers
🔹 Lead-qualification assistants that capture, score, and route leads automatically
🔹 Internal knowledge assistants that turn company data into instant answers for your team using RAG
🔹 Conversational AI with sentiment analysis and human-handoff fallback
🚀 **AI Voice Bots**
🔹 Outbound sales AI Voice Bots (VAPI, Retell AI, Bland AI, ElevenLabs)
🔹 Inbound receptionist bots for appointment scheduling and lead qualification
🔹 Twilio-integrated call flows with live CRM updates pushed through n8n and Zapier
🔹 Multilingual AI Voice Bots for global support
🚀 **AI Agents & Automation (n8n, Zapier, Make)**
🔹 n8n agent workflows with custom AI agent nodes connected to your stack
🔹 Zapier & Make automations with AI steps wired into 1,000+ apps
🔹 CRM automation across HubSpot, Salesforce, GoHighLevel
🔹 RAG pipelines on Pinecone / Qdrant, automated end-to-end with n8n and Zapier
**Professional Achievements**
🏆 Top Rated Plus on Upwork
✅ 100% Job Success Score
✅ 80% long-term repeat clients, 98% of clients recommend me
✅ 93% on-time delivery across all milestones
✅ Fluent English (verified)
✅ [X]+ AI agents and AI assistants deployed, [X]+ voice agents handling [X]k+ calls/month (replace with your real numbers)
**My Technical Stack**
🔹 AI Agents: LangChain, LangGraph, CrewAI, OpenAI GPT, Claude, function calling
🔹 RAG: Pinecone, Qdrant, vector databases, embeddings, document AI
🔹 Voice AI: VAPI, Retell AI, Bland AI, ElevenLabs, Twilio
🔹 Automation: n8n, Zapier, Make
🔹 Integrations: HubSpot, Salesforce, GoHighLevel, Slack, Gmail, Google Calendar
🔹 Development: Python (FastAPI/Django), PostgreSQL, AWS
**Whom I Work With**
➜ SMBs and agencies wanting an AI workforce that runs 24/7

➜ SaaS companies adding AI agent features to their product
➜ Service businesses replacing manual calls and chats with AI

Greetings! As an accomplished expert in web scraping and automation with over 3 years of experience, I bring a wide skill set to the table. Leveraging Python's power for nearly 5 years, I've developed diverse tools, including Instagram and Twitter scrapers and automation bots for Twitter profile creation. I also use AI models like Github Copilot,ChatGPT and GPT-4 to code in a more efficient way.
Moreover, I'm proficient in backend development with Flask and FastAPI, using Postgres for database management. My expertise also extends to bypassing bot detection mechanisms, assuring smooth operation of all bots.
Here are some projects I've completed:
- Instagram and Twitter Scrapers: Developed high-performance scrapers for data extraction.
- Twitter Profile Creation Bots: Automated the process of creating Twitter profiles.
- WhatsApp and Telegram AI Chatbots: Built AI chatbots using GPT-3.5 and GPT-4 for dynamic interactions.
- Crypto Bots: Created sandwich, arbitrage, and trading bots utilizing APIs from leading platforms.
- PAXG and GOLD Bots: Developed bots to exploit the spread between PAXG and GOLD.
Eager to apply my skills to new challenges, I'm always ready to take on new projects.
