🌐 Web Development | 🔄 Automations | 🧩 API Integrations | 🛡️ Clean, Reliable & Maintainable Code | 📊 Data Processing | 🕸️ Web Scraping & Data Mining | 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. 🤝 𝙍𝙚𝙖𝙙𝙮 𝙩𝙤 𝙂𝙚𝙩 𝙎𝙩𝙖𝙧𝙩𝙚𝙙?
