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.

I’m a Back-End Developer specializing in Django, Django REST Framework, PostgreSQL, and MySQL, with strong experience building secure, scalable, and well-structured APIs for real-world applications.

👋 Hi, I’m Aziza, a Top Rated Plus Python Backend Engineer with 7+ years of experience building backend systems, APIs, automation tools, data pipelines, and production-ready applications. I help businesses replace messy, manual, or outdated backend workflows with clean, reliable software that is easier to use, easier to maintain, and ready to scale. If you need someone who can step into an existing codebase, understand the business problem quickly, ask the right questions, and deliver without heavy supervision, I can help. 🚀 What I do best: • Build Python backend systems from scratch • Create and improve Django, DRF, FastAPI, Flask, and Django Ninja APIs • Convert Bash scripts and legacy workflows into modern Python applications • Build internal dashboards, admin tools, and automation platforms • Design web scraping and data extraction pipelines • Integrate third-party APIs, payments, authentication, and cloud services • Improve database structure, queries, performance, and reliability • Add Celery jobs, scheduled tasks, logging, and background processing • Debug production issues and clean up existing backend systems • Use Claude, Cursor, and AI tools to move faster while keeping code clean and production-ready 🛠️ Technologies I work with: ✅ Python ✅ Django ✅ Django REST Framework ✅ Django Ninja ✅ FastAPI ✅ Flask ✅ PostgreSQL ✅ MySQL ✅ MariaDB ✅ MongoDB ✅ Supabase ✅ Celery ✅ Redis ✅ AWS S3 ✅ AWS Lambda ✅ Railway ✅ Cloudflare ✅ Docker ✅ GitHub Actions ✅ Bitbucket ✅ Stripe API ✅ RevenueCat ✅ Firebase ✅ OneSignal ✅ Swagger / OpenAPI ✅ Pytest ✅ BeautifulSoup ✅ Selenium ✅ Claude ✅ Cursor 💼 Recent results: • Modernized 30+ fragmented Bash scripts into a clean Django web application • Recreated complex legacy logic in Python with better structure, logging, error handling, and documentation • Worked with PostgreSQL and MariaDB inside one Django project • Consolidated multiple API environments into a single Django REST Framework application • Built backend APIs and data workflows for a data-heavy analytics dashboard • Worked with scraping, onboarding flows, Supabase, Railway, Clerk, and Cloudflare • Delivered backend work that clients described as clean, efficient, well-structured, and easy to maintain 🤖 AI-assisted development: I actively use Claude, Cursor, and AI coding tools for research, planning, debugging, prompt work, refactoring, and implementation. I use AI to speed up development, but I still review, test, and structure the code carefully so the final result is reliable and maintainable. ✨ Why clients choose me: Clients describe me as a clear communicator, reliable, proactive, collaborative, detail-oriented, and committed to quality. I care about the real business goal behind the code. I do not just “finish tickets.” I help improve the system, reduce manual work, make workflows smoother, and leave behind code that other developers can understand and maintain.
