Hire the Best Python Developers

Python Full Stack Developer who steps in where products stall - fixing broken ownership, tightening architecture, and turning messy delivery into a system that actually ships 10+ years in web product development, I now lead UASOFTDEV as CTO & Co-Founder, building and scaling teams of senior Ukrainian engineers who can integrate fast and take real technical responsibility from day one. If your product is slowed down by handoff gaps, weak architecture, or fragmented ownership, I help turn it into a clear delivery process with strong technical control My strongest core role is a python developer for backend-heavy products, with additional experience in C# .NET when projects require enterprise-grade backend logic. When the scope expands, I work as a full stack developer with end-to-end ownership, or as a web developer focused on scalable execution. 📌 What I typically cover Web and Mobile Development backed by 10+ years of product work, supported by a python full stack developer approach when APIs and UI must evolve together Full-Stack Development aligned into 1 clear delivery flow, shaped through python full stack thinking for faster releases and fewer handoff gaps E-commerce Web Development across 3 core layers - business logic, integrations, and user flows - delivered with full stack python experience API development and Integration for internal platforms and 3rd-party systems, handled in a full stack developer python role when architecture must stay practical ⚙️ My current capability set covers React with JavaScript, Next.js, Nest.js and TypeScript, plus Vue.js and Angular. On the backend, I work with Node.js, laravel, python, Django, Flask, .NET, C++, Go, Ruby on Rails and Java. Mobile and cloud delivery includes iOS, Android, flutter, React Native, AWS, Azure, GCP, Docker, Kubernetes, and openstack. I also support CMS and platform work through wordpress, Drupal, Symfony, Magento and Shopify. 🛠️ Delivery across product layers Lean API products often benefit from a python full stack developer flask setup User-facing systems need a full stack web developer mindset when flow affects adoption Interface-heavy platforms grow faster with a full stack developer react profile Cross-layer execution works well in a full stack developer react python environment System reliability improves early with a backend python developer focus 🤖 I build AI features for real workflows, not for demo value alone. In that context, I work as a python ai developer on assistants, automation and internal tools. My python ai work is strongest where adoption matters, and clients also bring me in as an ai developer or ai software developer when implementation must connect product, backend, and rollout. 🧠 AI, frontend, and product execution ✔️Practical ai machine learning features tied to support, search, and operations ✔️Applied machine learning developer work when smart functionality must fit an existing product ✔️Business-facing machine learning integrations designed for measurable value ✔️Custom chatbot systems built with react python flows and fastapi services ✔️Scalable UI delivery as a react developer with clean html front end execution and thoughtful app design ☁️ I stay close to architecture because strong delivery depends on clear ownership. That is why I regularly handle back end development, step in as a backend developer when technical decisions affect release quality, and support python devops workflows across cloud and deployment planning. 🔧 Collaboration and adjacent exposure In a startup, delivery often means working beside a data scientist, then translating that work with a product manager into usable features. Release quality improves when a qa analyst joins early, especially in products shaped by compliance. Some founders also involve me as a startup consultant before code begins. ✔️Broader platform exposure includes sharepoint workflows, material ui dashboards, payment gateway implementation ✔️Cross-team delivery has also touched full stack java environments and adjacent java devops processes. ✔️Finance-related work has included trading python flows, algorithmic trading logic, binance integrations, and tools built for a trader. ✔️Adjacent product contexts have involved data entry operations, support for a journalist workflow, technical resume writing solutions, selected dall-e use cases, prototype work around crypto bot ideas, and tools requested by gaming developers. ✔️Growth-focused engagements may also involve a seo specialist, a practical it consultant, or teams building in marketing saas. 🌍 My domain expertise includes AI Startups, Data Analytics, Healthcare, Fintech, E-commerce agencies, IT Consulting/Softdev companies, Real Estate, Non-Profit, Blockchain and Gambling 🤝 If you need senior technical ownership Python Full Stack Developer, fast ramp-up and delivery that stays aligned with business goals, let’s talk."

🏆 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.

They struggle to turn those models into systems that improve margins, reduce operational overhead, increase employee productivity, create new revenue opportunities, or deliver a measurable competitive advantage. I work with startups, SMBs, and enterprise teams to build AI-native products, intelligent internal tools, and custom software systems that become part of how the business operates every day. Whether that means automating manual workflows, transforming institutional knowledge into a competitive asset, improving decision-making, or creating entirely new AI-powered products, the goal is always the same: tangible business outcomes rather than technology experiments. Over the past decade, I have worked across healthcare, insurance, life sciences, compliance, real estate, financial services, workforce management, and knowledge-intensive industries where accuracy, reliability, and adoption matter as much as the technology itself. My focus is not on adding AI to your business. My focus is identifying where intelligence creates the highest economic leverage and building the systems to capture it. If you are evaluating an AI initiative, exploring a product idea, or looking to build internal AI capabilities that create lasting business value, send me a message and let's discuss what the highest-leverage opportunity looks like for your organization.
