Hire the Best iPad App Developers in Zaporizhzhya, UA

Results-first engineering — every achievement below is backed by a number. 🔥 ACHIEVEMENTS ✔️ As a Python Developer, I automated 70% of manual procurement workflows for a Norwegian AI startup and cut cycle time by 30%, working across the pipeline as an AI Developer as well as the Python Developer who wrote the code. ✔️ As an AI Developer, I delivered a working AI price-recommendation engine in 12 weeks — 500K+ product records processed daily, 85% model accuracy, built end-to-end as a Python Developer using TensorFlow and Scikit-Learn. ✔️ As a Full Stack Developer, I shipped a Python/AWS data pipeline for an IoT utility platform: 1M+ smart-meter readings processed daily across 200,000+ devices, latency down 35%. ✔️ As a Python Developer, I built an AI demand-prediction and fleet-allocation system for a ride-hailing platform: +28% fleet utilisation, –32% rider wait times. ✔️ As a Full Stack Developer, I've delivered 25+ end-to-end products — React front ends, Django and Flask back ends, PostgreSQL data layers — with 28% lower delivery risk than typical handoff-heavy teams. ✔️ As a Python Developer and AI Developer combined, I built a multilingual AI citizen-support system for a government client: –45% first-line requests, +35% faster response times. ✔️ As a Full Stack Developer, I've processed 10x more data sources per project than the baseline system I replaced, keeping the Python Developer codebase and the AI Developer model layer in one repo. 🎯 HOW I WORK — PYTHON DEVELOPER, AI DEVELOPER, FULL STACK DEVELOPER As a Python Developer, I build backend systems in Django, Flask, and FastAPI, with REST API layers, PostgreSQL and MySQL underneath, deployed with Docker and tracked in Git. As an AI Developer, I train and ship Machine Learning models — TensorFlow, PyTorch, Scikit-Learn — real Machine Learning Python work in production, not notebooks that never ship. My range spans AI Automation, Gen AI, LLM, and RAG pipelines, AI Agents and AI Chatbots with seamless handoff, AI Voice Agent integrations for on-device inference, and Full Stack AI SaaS Developer builds where I own the model, the API, and the dashboard. As a Full Stack Developer, I connect that backend to a React or Angular frontend, using JavaScript and Java where the stack calls for it, HTML5, CSS3, Bootstrap, and jQuery for the UI layer — with Software Architecture & Design decisions made up front rather than bolted on later. 🌐 WEB, DATA & INTEGRATION DEPTH As a Web Developer and Web Scraping Developer, I've built Python Web Development admin panels, Full Stack Python Developer Flask products, and Web Scraping Python pipelines — turning raw data into clean, deduplicated datasets. My Data Extraction work covers Web Scraping Real Estate listings, Web Scraping Data Mining systems, and automated Python scripts running daily without breaking. Amazon API Integration, Shopify API Integration — always closing with clean API Documentation, plus broader integrations across CRMs and payment providers. As a DevOps Engineer and Cloud Engineer, I deploy on AWS and AWS Bedrock, configure Docker, Git, and CI/CD pipelines, and integrate N8N, Zapier, Make, and GHL workflow automation for SaaS and MVP platforms. 🌍 ROLES CLIENTS HAVE HIRED ME FOR As a Django Developer and FastAPI Developer, I've rebuilt legacy systems and shipped greenfield APIs. As a Flask Developer and Backend Developer, I've delivered microservices and event-driven pipelines. As a React Developer and Frontend Developer, I've owned interface work end to end. As a WordPress Developer and PHP Developer, I've handled CMS builds and legacy migrations. As a GIS Developer, I've integrated Mapbox, QGIS, and ArcGIS into logistics platforms. As an Algorithmic Trading Developer, I've built AI Trading and Forex analytics systems. Whatever the label — SaaS Developer, MVP Developer, FinTech Developer, or ML Engineer — delivery is the same: a Full Stack Web Developer's ownership of the whole product, backed by Laravel and PHP experience for teams migrating off older systems. ⚙️ TECH STACK — BUILT INTO EVERY PROJECT As a Python Developer, I've used Python, Django, Flask, FastAPI, PostgreSQL, MySQL, Docker, and Git to ship backends processing millions of records daily. As a Full Stack Developer, I've connected React, Angular, Node.js, JavaScript, HTML5, CSS3, Bootstrap, and jQuery frontends to production-grade APIs. As an AI Developer and ML Engineer, I've shipped TensorFlow, PyTorch, Scikit-Learn, LLM, RAG, and Gen AI systems with AWS Bedrock and SageMaker. As a Web Scraping Developer, I've built Scrapy, Selenium, and BeautifulSoup pipelines with full Data Scraping and Data Extraction automation. 🚀 Looking for a Python Developer who thinks like an AI Developer and builds like a Full Stack Developer?
