🏆 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.
