Over 15 years I was involved in versatile software development projects. I am now mostly engaged in full-stack web development. I am most proficient in API design and backend development using Django / FastAPI / Flask framework, MySQL / PostgreSQL, Celery, Redis. I have experience in DevOps, familiar with Docker, Kubernetes framework, ArgoCD, Amazon cloud services. Also I am capable of website front-end development using Alpine-js, HTMX, Tailwind CSS, Bootstrap, JQuery. I have experience in cross-platform desktop and mobile applications development using Qt\PyQt and kivy. I prefer to write perfect code with automated tests. Please look at my past work in portfolio and Github profile.

I build production-grade AI products for health and fitness companies. LLM/RAG, FastAPI, React, Flutter. Idea, or a broken MVP, to a real product that holds up. If you validated an idea and now need it built right, or you've got a vibe-coded MVP that's breaking and can't scale, that's exactly what I do. I take health and fitness AI products from concept to launch, the kind real users actually use every day. What I've shipped, all architected and built by me end to end: CuePilates, a full AI SaaS on Next.js, Supabase, Stripe and OpenAI, idea to launch in under a month. A clinical AI platform doctors use daily. DietTalk, live on the App Store and Google Play. How I work: a free call to scope it, then a working prototype of your core feature in about 2 weeks that you can use yourself, then the full build in phases where you see working software and approve each phase before you pay for it. Weekly demos, daily comms, clean handover so you own it. Secure, encrypted data handling, with production standards baked in: auth, payments, multi-tenant, scale. Not a demo that falls over at launch. If you're tired of cheap builds that leave you stuck, let's talk.

I build systems that actually ship. I'm a full-stack Python engineer with 3 years of experience building backend APIs, AI agents, and end-to-end automation pipelines for real businesses. I'm also one of a small group of engineers who works deeply within the Claude AI ecosystem not just calling the API, but building with Claude Code, designing MCP servers, seting up Claude-Cowork for businesses and deploying agentic systems that use Claude the way Anthropic intended it to be used. My current project is Whaply - a WhatsApp AI agent platform that lets businesses deploy intelligent, human-aware chatbots that automatically pause when a human agent joins the conversation. It's built on FastAPI, Supabase, and the WhatsApp Business API with multi-LLM support. I didn't just plan it I architected, built, and deployed it myself. That's how I work with clients too. --- WHAT I BUILD: Python backend systems using FastAPI — microservices, RESTful APIs, webhook integrations, OAuth authentication, and custom API wrappers built to scale. AI agents and LLM-powered tools — deep integrations with Claude (Anthropic), OpenAI, and Gemini with real decision-making logic, not just prompt wrappers. This includes building custom MCP servers that extend what Claude can do, agentic coding workflows with Claude Code, and enterprise-grade automations using Cowork and the broader Claude tooling ecosystem. Voice AI systems using Vapi and Retell AI — intelligent phone agents that handle real conversations, not just demos. Automation pipelines with n8n — connecting CRMs, databases, cloud platforms, and custom APIs into systems that run without babysitting. Full-stack applications — React or Next.js frontends backed by robust Python APIs, built for real users. --- WHAT MAKES ME DIFFERENT: I'm not a low-code freelancer who drags blocks around until something works. I write the backend, design the architecture, handle the integrations, and think about what happens when things break. On the Claude side specifically — I've built production MCP servers, shipped agentic pipelines using Claude Code, and understand the Claude API at a level most engineers don't reach. If you're building something in the Anthropic ecosystem or want to, I'm one of the few freelancers who actually lives there. I've completed 10+ contracts with a 100% Job Success Score. Every project I take on, I treat like it has my name on it — because it does. --- BEST FIT FOR: · Founders who need a technical partner, not just an executor · Businesses looking to integrate Claude AI into their products or workflows · Teams building AI-powered products that need to work in the real world · Anyone who's been burned by freelancers who disappeared after the demo If that sounds like you, let's talk.

A short Introduction: I help founders and operations teams automate manual workflows using Python FastAPI framework, Langchain, and AI agents - saving 10–30+ hours per week. Recent work includes: • Lead automation (Webhook → Claude → Gmail → CRM) • AI document processing pipelines • Internal dashboards powered by FastAPI + automation • Automated workflows with Airtable, Gmail, Slack, webhooks, APIs If you’re wasting time on repetitive work, I build systems that run reliably in production. 🧠 AI Agents & AI Automation - LangGraph, LangChain - Playwright / Browser Automation (when required) - API orchestration (Gmail, Payments, CRM, Marketplaces, Internal tools) 🤖 Generative AI & Large Language Models (LLMs) - ChatGPT / OpenAI, Anthropic, open-source LLMs - Prompt Engineering & Prompt Optimization - Function calling, tool-use, structured outputs - Token-efficient and cost-optimized architectures 🤖 Chatbots & Conversational AI (Text & Voice) - AI chatbots for customer support, internal tools, and workflow automation - LLM-powered chatbots using LangChain, LangGraph, OpenAI Assistants, RAG pipelines - Enterprise chatbot platforms: Vertex AI (Gemini), Dialogflow CX, OpenAI, Anthropic - Context-aware, multi-turn conversations with memory, & structured outputs - Voice & speech agents using Vapi, STT/TTS pipelines, real-time call flows - Web, WhatsApp, Slack, CRM, and API-based chatbot integrations - Conversation logging, summaries, monitoring, and analytics 📚 Retrieval-Augmented Generation (RAG) & NLP - Semantic search & vector databases - Document ingestion (PDFs, reports, policies, tables) - Context retrieval with nested references - Question-Answering & knowledge systems 🧮 Core Stack - Frameworks: FastAPI - Tools: VAPI, Retell, Airtable - CRM: GHL, NocoDB, Hubspot Most of my clients come to me after trying low-cost automation that broke in production. My focus is reliability, clarity, and maintainability, not just “making it work once

Most AI SaaS ideas look simple in the beginning. Connect an AI API → Build a few screens. → Add login → Add payments → Launch. But once real users enter the picture, the product needs much more than a quick demo. → The dashboard has to feel clean. → The backend has to be reliable. → The AI feature has to work with real data. → Subscriptions need to be handled properly. → Users need accounts, roles, admin controls, and a smooth experience from day one. That is the difference between a quick demo and a scalable, production ready SaaS. And that is exactly what I build. ✅ 6+ Years of Experience as a React Full Stack Developer & Full-Stack Web & SaaS Development Specialist ✅ Specialized in React, Next.js, Node.js, TypeScript, Python & API Integrations, Fast Api ✅ Helping Startups, SaaS Businesses & Growing Companies Build Scalable Web Applications as a Full Stack Developer ✅ Trusted by Founders, Agencies, SaaS Teams & E-Commerce Brands I help startups, businesses, and growing teams build modern web applications, SaaS platforms, dashboards, APIs, and backend systems tailored to their business goals.
