You will get Modern async OR lightweight API | Python Developer
Top Rated
Project details
You’ll get a production-ready Python API built for speed, reliability, and scale — whether you need a high-concurrency async backend (FastAPI/async stack) or a clean lightweight API for simple, fast delivery.
I focus on clear architecture, secure endpoints, clean code, and performance from day one. From authentication and database integration to deployment-ready structure, your API will be built to be easy to maintain and ready for real users.
Perfect if you’re launching an MVP, scaling backend services, or replacing a slow/overcomplicated API with something modern, efficient, and robust.

Ivano - Frankivks, Ukraine - 2:49 pm local time
Hi! I'm a Python Developer with 9+ years of experience and a PhD in Telecommunications Engineering, specializing in Python backend development, automation, and data pipelines.
👋 Whether you need a Python Full Stack Developer to ship a production-grade web app, a Python Developer AWS to deploy scalable microservices, a Python Full Stack Developer Flask expert to build modern backend-driven applications, or a Python AI Developer to wire up intelligent automations — I deliver clean, reliable, maintainable solutions that solve real problems. If you're also searching for a solid web developer, full-stack developer — I bring the same professional rigour to every project.
🌐 Web Development & Backend Engineering Building modern, robust applications using Python (FastAPI, Sanic, BlackSheep, Flask, Django), with clean architecture and best practices. As a Python Full Stack Developer I also connect backends to React frontends, delivering full end-to-end products.
• REST APIs, GraphQL, microservices architecture, and event-driven systems
• Python Full Stack Developer Flask & Django apps — from MVPs to enterprise-scale
• Clean architecture, SOLID principles, OOP, and maintainable codebases
🔄 Automating complex business processes using N8N, Make, and Python to eliminate manual work, reduce errors, and boost operational speed.
• Clients routinely save 100+ hours/month after automation delivery
• Broker commission calculation pipelines — 70% reduction in processing time
• Python AI Developer integrations with OpenAI and LLM-powered workflow tools
🧩 API Integrations Seamlessly connecting services and platforms through REST APIs, OAuth2, JWT, and custom integration solutions. Integrated 35+ third-party APIs into live production systems.
• Stripe, PayPal, SendGrid, Twilio, Google Maps, Salesforce, and more
• Keycloak, Kong Gateway, Google Apigee, Apache Mesos/Aurora
• Healthcare, Fintech, Telecom, and SaaS platform integrations
🕸️ Extracting valuable data from any website using HTTP, Scrapy, BeautifulSoup, Selenium WebDriver, and custom crawlers — delivered clean and ready for analysis.
• High-volume scraping pipelines with anti-detection and proxy rotation
• Grain price dashboards with real-time market data feeds
• Sentiment analysis of articles and reports for retail manufacturers
📊 Data Processing & ETL Transforming, cleaning, and analyzing large datasets using Pandas, SQL, and NoSQL databases — with full pipeline automation from source to insight.
• PostgreSQL, MySQL, MongoDB, Redis, SQLite, Amazon Aurora
• 50–70% faster query response times on high-load production databases
• 100% data integrity preserved on legacy system migrations
🛡️ Clean, Reliable & Maintainable Code Following best coding practices, with deep knowledge of OOP, SOLID, unit testing, and CI/CD — code that teams can own long after delivery.
• 83%+ unit test coverage on complex integrations
• Docker, GitHub Actions, GitLab CI, Nginx — full DevOps lifecycle as Python Developer AWS
• Passed all security audits with 100% compliance
🐍 Python Developer — Core Expertise
As a Python Developer I build backend systems, automation pipelines, and data-driven applications that are engineered to last. My work as a Python Developer covers the full spectrum — from designing reliable REST APIs and microservices to building complex ETL workflows and integrating third-party platforms. Clients come to me as their Python Developer when they need more than working code: they need systems that are observable, maintainable, and ready to scale. Whether the project calls for a Python Full Stack Developer delivering end-to-end web applications, or a focused Python Developer AWS deploying cloud-native services, I bring the same production-grade mindset to every engagement.
🤖 Python AI Developer & Intelligent Automation
A growing part of my work as a Python Developer involves building intelligent, automated systems that go beyond traditional scripting. As a Python AI Developer, I integrate LLMs, AI agents, and MCP (Model Context Protocol) into real backend workflows — not as experiments, but as production features with proper error handling, observability, and cost control. I work with tools like N8N, Make, and custom Python orchestration to automate high-volume business processes that previously required significant manual effort. This combination of deep Python Developer expertise and hands-on AI integration experience means I can design automation that is both technically sound and genuinely useful to the business.
