FREE Startup Strategy & Tech Consultation Thinking of building a web app or bot? I’m offering a free session to help you skip the "trial and error" phase. Having built 10+ production-ready apps and bots from scratch, I help you bridge the gap between an idea and a working product. I build things that actually work not only on my local machine. I've spent years building web apps with Python and React. Here are some things I've done: * Built 10+ bots and web apps for users * Used Python, React, Django, Flask, REST APIs and Docker * Full-stack development from start to finish • Web Apps & APIs: Most of my work is on the backend: * Django and Flask APIs * PostgreSQL databases * Authentication flows * Integrating with services On the frontend I use React with Vite or Next.js. and build functional user interfaces. • Bots & Automations I use aiogram, webhooks and async handler to build Telegram and Discord bots. • Infra & Deployment: Docker is part of my workflow. I compose files, containers and GitLab CI/CD or GitHub Actions. • How I Actually Work: * I ask questions before I start coding * I push updates without being reminded * If somethings unclear I flag it • Good Fit If: * You need working software, not someone who agrees with you * Your stack is Python or React (or both) * You want someone who takes ownership of the task Keywords: React / Next.js | Node.js | TypeScript | Full-Stack Development| Supabase | PostgreSQL | REST API Development | Express.js | Tailwind CSS | API Integration | Stripe | OpenAI API | Vercel | Docker | JavaScript | MongoDB |Firebase |AWS |LangChain |Web Application Development

𝐏𝐲𝐭𝐡𝐨𝐧 𝐀𝐈 𝐄𝐧𝐠𝐢𝐧𝐞𝐞𝐫 • 𝐑𝐀𝐆 𝐒𝐲𝐬𝐭𝐞𝐦𝐬 • 𝐀𝐈 𝐀𝐠𝐞𝐧𝐭𝐬 • 𝐅𝐚𝐬𝐭𝐀𝐏𝐈 • 𝐄𝐧𝐭𝐞𝐫𝐩𝐫𝐢𝐬𝐞 𝐋𝐋𝐌 𝐀𝐩𝐩𝐥𝐢𝐜𝐚𝐭𝐢𝐨𝐧𝐬 The most expensive AI mistake isn't choosing the wrong model. It's choosing the wrong architecture. Anyone can connect GPT to an app. Very few engineers can build what comes after that. I don’t just pitch dreams. I ship results. You’re not here to experiment. You’re here to win. If you're building an AI product, you're probably facing one of these challenges: • You have an idea but need someone to architect it properly. • Your chatbot works, but isn't reliable enough for real users. • Your AI backend has become difficult to maintain. • You need an engineer who can own the technical side instead of simply completing tickets. That's where I come in. I help startups, SaaS companies, and enterprise teams turn AI ideas into production-ready products that users can actually depend on. Over the last few years I've built AI systems across healthcare, real estate, education, compliance, and SaaS, including custom chatbots, enterprise RAG platforms, multi-agent workflows, document intelligence systems, AI automation, and scalable Python backends. Unlike developers who simply integrate APIs, I focus on building complete AI products—from architecture and retrieval pipelines to deployment and long-term scalability. What I Build ✓ Enterprise RAG Platforms ✓ AI Chatbots trained on proprietary company knowledge ✓ Multi-Agent AI Systems ✓ AI Workflow Automation ✓ Document Intelligence Platforms ✓ FastAPI & Python Backends ✓ AI SaaS Products ✓ Secure API Integrations ✓ AI Search & Recommendation Systems Recent Projects • Built an enterprise knowledge assistant capable of searching and retrieving answers from thousands of internal documents. • Developed AI-powered SaaS platforms using FastAPI, LangChain, OpenAI, Pinecone, and vector search. • Designed multi-agent workflows that automate research, reasoning, and business processes. • Delivered production AI systems for startups preparing for customer launch and investor demonstrations. My Engineering Philosophy I don't believe every problem needs another AI framework. I choose the simplest architecture that delivers the right outcome. That means writing software that's maintainable, scalable, and easy for your team to extend long after launch. Most of my clients hire me because they need someone who can think through the product, not just write code.
