I build AI Agents, AI Chatbots, RAG systems, workflow automation platforms, SaaS applications, and custom web software for startups and established businesses. For the past nine years, I have worked with companies across FinTech, HealthTech, Aviation, Real Estate, E-Commerce, Logistics, and SaaS, helping them automate processes, launch products, improve operations, and scale their platforms. Most clients come to me when they need more than a developer. They need someone who can understand the business requirements, design the architecture, build the system, integrate third-party services, deploy it, and support it after launch. I have delivered aviation training platforms, healthcare scheduling systems, enterprise CRM applications, AI-powered document processing tools, RAG knowledge assistants, workflow automation systems, analytics platforms, custom business software, and multi-tenant SaaS products used by real customers every day. Core areas I can help with: ✅ AI Agent Development ✅ AI Chatbot Development ✅ Retrieval-Augmented Generation (RAG) ✅ OpenAI, Claude, and Gemini Integrations ✅ LangChain, LangGraph, and LlamaIndex ✅ MCP Server Development ✅ n8n, Make, and Workflow Automation ✅ SaaS Application Development ✅ Full-Stack Web Development ✅ Python, FastAPI, Django ✅ React, Next.js, Node.js, Laravel ✅ CRM Development and Business Applications ✅ API Integrations and Third-Party Services ✅ PostgreSQL, MongoDB, Supabase ✅ AWS, Docker, Kubernetes Some recent projects include AI-powered SaaS platforms, healthcare workflow automation, aviation training software, CRM systems, document processing tools, invoice automation solutions, analytics dashboards, enterprise web applications, and intelligent business automation systems. I work across the full lifecycle of a product, from planning and architecture to development, deployment, integrations, optimisation, and long-term support. The goal is always the same: build reliable software that solves real business problems and continues to perform as the business grows. If you already have requirements, documentation, wireframes, or even just an idea, send them over. I will review everything, identify potential challenges, and outline the most practical approach before development begins. For larger projects, you can also book a consultation directly through my profile to discuss architecture, scope, timelines, and technical decisions before committing to development.

🏆 Top 1% Stack Overflow | Open-Source Publisher | 8+ Years Senior Engineering I specialize in end-to-end AI and full-stack development, covering architecture, implementation, and deployment. I work with founders, SaaS teams, and product leaders to build AI-powered and full-stack applications designed to handle growth in users, data volume, and evolving requirements. My work includes AI chatbots, internal AI agents, data-driven dashboards, and full-scale web applications built with Laravel/PHP, Next.js React, SvelteKit, Vue, TypeScript, Node, FastAPI, Django, and AWS/GCP/Azure. ✅ Testimonial 👉 “After working with developers for the past 20 years, I can confidently say that Eryk is among the most talented developers I have ever worked with.” ⭐️⭐️⭐️⭐️⭐️ 👉 “Eryk is a highly capable engineer who delivers results quickly. We were searching for a full-time programmer for our start-up, and he stood out through his technical depth and speed of execution. We can confidently recommend him.” ⭐️⭐️⭐️⭐️⭐️ My approach to engineering is rooted in the critical thinking and risk management that define this discipline. I typically opt for FastAPI when low-latency AI endpoints are paramount, Django when admin-heavy workflows and integrity are crucial, and Next.js when SEO or app-like user experiences are necessary. The stack is focused on addressing specific problems rather than following trends. I work primarily in TypeScript, building clean, maintainable applications with Next.js, React, SvelteKit, and Vue, based on product needs and team structure. On the backend, I design REST and GraphQL APIs and backend services using Laravel, FastAPI, Django, and Node.js, and leverage platforms like Supabase and Firebase when speed, reliability, and simplicity are priorities. I’ve implemented authentication, real-time features, storage, and background workflows across both platforms in live production environments. From an infrastructure and deployment standpoint, my work includes AWS, GCP, Docker, CI/CD pipelines, serverless deployments, cloud backends, and production DevOps workflows, supporting scalable and cost-aware systems. Much of my recent work centers on designing and shipping production AI systems, including AI interviewers, AI video generators, ChatGPT-style applications, RAG-based knowledge systems, and internal AI tools for reporting and automation. In these projects, success depends less on model choice and more on how the surrounding system is designed. I account for context handling, cost control, observability, and system boundaries early so the product remains stable as it evolves. I’m a senior full-stack engineer with 8+ years of experience, and I usually take full ownership of systems from architecture, backend logic, AI integration, frontend, and deployment. This leads to clearer decisions, smoother execution, and far fewer surprises after launch. Clients usually reach out to me when: 👉 An MVP needs to mature into a long-term product 👉 An AI feature must move from prototype to real usage 👉 A system is slowing down, becoming fragile, or growing costly 👉 They want one engineer who can own the full technical picture I’m direct, proactive, and transparent. I flag risks early, explain trade-offs clearly, and help teams make decisions they won’t regret six months later. If you’re looking for a developer who can think like an owner, build like an engineer, and communicate like a partner, we’ll work well together. Looking forward to speaking, Eryk S.
