I help founders and operations teams turn business processes into reliable web portals, internal tools, dashboards, and SaaS MVPs. My strongest area is backend-heavy development: Laravel, Symfony, Yii/legacy PHP when needed, API integrations, roles/permissions, workflows, reports, and data-heavy systems. For frontend, my strongest stack is Vue.js, with React as a secondary option. I am not just a coder. I usually start by understanding how your business works, what users need to do, which edge cases matter, and what reports or automation will save time. Then I help turn that into a clear prototype, first milestone, POC, or MVP. Recent examples: - Designed and built an insurance broker portal from scratch: roles, API integration with a policy issuing system, tariff calculation, policy issuing flow, commission management, and reports. The first policy was issued 2.5 months after the idea. - Built an AI chatbot system for a cosmetics e-commerce store with product recommendations, catalog Q&A, cart/order flow, Instagram Direct + Telegram integration, admin panel, dialog logging, vector search, Elasticsearch, PostgreSQL, and 20+ prompts/agents. Token cost per completed order flow was under $0.02. - Built and worked on analytics-heavy systems, including e-commerce dashboards with 10k+ daily orders, adtech systems with 10m+ daily views, and CRM/ERP-style workflows. What I can help with: - Business portals and internal tools from scratch - Workflow automation and role-based systems - SaaS MVPs and admin dashboards - Complex reports and analytics-heavy backends - Laravel/Symfony/Vue development - API integrations and business process automation - AI integrations when they bring real business value My preferred process for new products: 1. Discovery call to understand your idea and business flow. 2. Prototype or workflow description with clear business tasks. 3. Client approval and scope adjustment. 4. POC/MVP development. If the project needs UI/UX, I can involve a trusted designer while staying responsible for the technical delivery. I prefer to start with a small, useful first step: an audit, prototype, first milestone, or technical plan. If we work well together, I am open to long-term hourly work.

👋 I'm Yevhen, an AI Developer, Machine Learning Developer, Python Developer, AI Architect with 19+ years of experience designing intelligent software for startups, SaaS companies, and enterprise teams. 🏆 As an AI Developer, I help businesses move beyond simple API integrations by building complete AI products that solve real operational problems. As an AI Developer, I design production-ready AI platforms that combine Machine Learning, AI Agents, intelligent automation, and scalable backend systems. My work includes AI Automation, AI Chatbots, AI Assistants, intelligent document processing, business analytics, semantic search, and enterprise AI platforms that process millions of data points and automate complex business workflows. 🦾 As a Machine Learning Developer, Python Developer, and AI Developer, I design scalable AI architectures using OpenAI API, Claude API, RAG, LangChain, LangGraph, LlamaIndex, CrewAI, FastAPI, Vector Database, Prompt Engineering, Workflow Automation, Business Automation, Document Automation, CRM Automation, Semantic Search, modern Python microservices, Zapier, and .NET integrations where required. Over the last several years I've built production AI systems including AI-powered document intelligence, AI Agent platforms, enterprise chatbots, legal document analysis, market research automation, forecasting platforms, brand monitoring systems, virtual assistants, recommendation engines, and intelligent business dashboards. As an AI Developer and Machine Learning Developer, I focus on solutions that are reliable in production rather than experimental prototypes. Whether the goal is building a new AI SaaS product, integrating AI into an existing platform, deploying AI Agents, implementing Machine Learning models, or creating large-scale automation workflows with Zapier, I work as an AI Developer, Machine Learning Developer, and Python Developer, delivering production-ready systems designed for long-term scalability, reliability, and measurable business value. 🎗️ As an AI Developer, I believe successful AI projects are built around business workflows rather than individual models. Every AI Developer can connect an API, but creating AI systems that remain reliable, scalable, and maintainable in production requires the right architecture, engineering practices, and continuous optimization. 🚀 As a Machine Learning Developer, I build solutions that combine Machine Learning, AI ML, Predictive Analytics, NLP, Deep Learning, Computer Vision, Recommendation Systems, intelligent search, anomaly detection, forecasting, and decision-support systems. My experience covers ML Pipelines, Model Training, Model Deployment, Model Optimization, Feature Engineering, Fine-tuning, LLM Fine-tuning, Embeddings, and modern MLOps workflows using TensorFlow, PyTorch, Scikit-learn, XGBoost, and even ML .NET where project requirements demand it. As an AI Developer and Python Developer, I've developed enterprise AI solutions including AI-powered document processing, legal AI assistants, AI Chatbots, AI Agent Development, intelligent reporting systems, market research automation, AI-powered forecasting platforms, virtual assistants with long-term memory, brand monitoring platforms, AI Copilots, recommendation engines, semantic search systems, and enterprise knowledge platforms powered by RAG, Vector Database, LangChain, LangGraph, LlamaIndex, CrewAI, MCP, OpenAI API, Claude API, and GPT-4. 💡 One of the things I enjoy most as an AI Developer is working closely with founders, product teams, and technical leaders from the earliest product discussions through production deployment. Good AI software is rarely just about selecting the right model—it requires understanding business processes, user behavior, data quality, scalability, and long-term maintenance. That combination of product thinking and engineering allows me to build AI solutions that continue delivering value long after the first release. Throughout my career as a Machine Learning Developer and Python Developer, I've worked on products for SaaS companies, ecommerce businesses, legal technology, enterprise operations, analytics platforms, intelligent search, forecasting, and business automation. Every project is different, but the objective remains the same: reduce manual work, improve decision-making, and help businesses grow through practical AI rather than experimentation. I believe successful AI products are built iteratively. Start with a measurable business problem, validate the solution quickly, improve it using real user feedback, and continue evolving the platform over time. 💡 If you're looking for an AI Developer, Machine Learning Developer, AI Champion or Python Developer who understands both advanced AI technologies and real business challenges, I'd be happy to help design and build an AI solution that is scalable, maintainable, and ready for production from day one.
