Hire the Best Python Developers

Most SaaS products dont fail because of ideas... They fail because they're built without scalability, reliability, or the right architecture. Whether it's a AI automation, web application, mobile app, or backend system, poor implementation leads to technical debt, unstable deployments and software that's difficult to maintain.

🏆 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.

𝗦𝗰𝗮𝗹𝗲 | 𝗠𝗶𝗴𝗿𝗮𝘁𝗲 | 𝗗𝗲𝗽𝗹𝗼𝘆 You have a visionary SaaS or AI product idea. You don't want to manage a scattered team of backend developers, DevOps engineers, and ML specialists, and you definitely don't want to micromanage tasks. You need a single, accountable technical partner to architect the system, solve the hard problems, and turn your idea into a scalable reality. I’m a Computer Science grad (first-class), but I don't just live in the theory. I combine a heavy academic background in math, stats, and ML with fast, practical execution. I don't just write code. I take ownership of the whole project: the design, the architecture, and the infrastructure. 🧠 𝗛𝗼𝘄 𝗜 𝗔𝗽𝗽𝗿𝗼𝗮𝗰𝗵 𝗬𝗼𝘂𝗿 𝗦𝘆𝘀𝘁𝗲𝗺: When you hand me a prototype, an MVP, or even just a wireframe, my first step is mapping the architecture. I am a natural problem solver, so I look at the big picture first. I treat your product like a business asset and focus on the hard realities: 🔹 Can we launch the MVP faster to validate the market? 🔹 Does it do exactly what your users need? 🔹 Is the AWS bill optimized, or are we burning money? 🔹 Will it crash if traffic spikes tomorrow? 🔹 Is your proprietary data actually secure? 🔹 If a server dies, is the database instantly recoverable? 📈 𝗥𝗲𝗰𝗲𝗻𝘁 𝗪𝗶𝗻𝘀 & 𝗪𝗵𝗮𝘁 𝗜 𝗗𝗲𝗹𝗶𝘃𝗲𝗿: 🔹 𝗜𝗻𝗳𝗿𝗮𝘀𝘁𝗿𝘂𝗰𝘁𝘂𝗿𝗲 𝗦𝗰𝗮𝗹𝗶𝗻𝗴 & 𝗖𝗼𝘀𝘁 𝗢𝗽𝘁𝗶𝗺𝗶𝘇𝗮𝘁𝗶𝗼𝗻: Recently, completely re-architected a system to handle 𝟰𝟬𝘅 𝗰𝗼𝗻𝗰𝘂𝗿𝗿𝗲𝗻𝘁 𝗽𝗿𝗼𝗰𝗲𝘀𝘀𝗶𝗻𝗴 while achieving a 𝟳𝟬% 𝗰𝗼𝘀𝘁 𝗼𝗽𝘁𝗶𝗺𝗶𝘇𝗮𝘁𝗶𝗼𝗻 on cloud spending. 🔹 𝗔𝗜-𝗡𝗮𝘁𝗶𝘃𝗲 𝗦𝗮𝗮𝗦 𝗔𝗿𝗰𝗵𝗶𝘁𝗲𝗰𝘁𝘂𝗿𝗲: I use my deep learning research experience to build secure, private LLM and RAG pipelines tailored to your business data. 🔹 𝗔𝘂𝘁𝗼𝗺𝗮𝘁𝗲𝗱 𝗖𝗹𝗼𝘂𝗱 𝗜𝗻𝗳𝗿𝗮𝘀𝘁𝗿𝘂𝗰𝘁𝘂𝗿𝗲 (𝗗𝗲𝘃𝗢𝗽𝘀): I architect zero-downtime CI/CD pipelines and configure AWS/GCP environments so you can ship features fast. 🔹 𝗕𝘂𝗹𝗹𝗲𝘁𝗽𝗿𝗼𝗼𝗳 𝗕𝗮𝗰𝗸𝗲𝗻𝗱 𝗦𝘆𝘀𝘁𝗲𝗺𝘀: I engineer high-performance backends (Django, Node) that won't crash when your user base scales. 🤝𝗠𝘆 𝗪𝗼𝗿𝗸𝗶𝗻𝗴 𝗦𝘁𝘆𝗹𝗲: I work best with founders and small teams who need a leader. You bring the business problem and the priorities — what matters next and why. I own the rest: the architecture, how the work gets broken down, and the delivery. I run it in focused sprints against agreed goals, with async updates and a call when a real decision needs one — so you get momentum without daily standups eating your week. When you hire me, you are not buying hours of typing, or a developer to assign tickets to. You are buying the judgment, speed, and technical leadership required to win — and a clean, production-ready product handed back to you. Let's look at your system and get it running right.
