Hire the Best Flask Developers & Programmers
in Ukraine

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 an AI Developer, I built an NLP patient-support layer for a telemedicine platform: –45% first-line support requests, +30% faster appointment booking. ✔️ 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 developer zapier automations, the app developer with ai role adding AI-native features to an existing product, ios developer ai integrations for on-device inference, and full stack ai saas developer builds where I own the model, the API, and the dashboard clients use to watch it work. As a full stack developer, I connect that backend to a React front end, or an Angular one, using javascript and java where the stack calls for it, HTML5, CSS3, Bootstrap and jQuery for the UI, and Software Architecture & Design decisions made up front rather than bolted on later. 🌐 WEB, DATA & INTEGRATION DEPTH As a web developer I've built everything from python web development admin panels to full python full stack developer flask products, and as a web developer I've also turned a web scraping job into a clean, deduplicated dataset ready for a data scientist to model — with a data scientist's eye for what "clean" actually means. My web scraping and data extraction pipelines have covered web scrapping real estate listings, web scrapping data mining, python web scrapping scripts, general web scrapping data jobs, and the occasional web srapping task that needed to run daily without breaking. As an api developer I've handled api integration end to end — api wordpress plugins, facebook api developer connections, amazon api integration and shopify api integration checkouts — always closing with clean api documentation, plus broader api integrations work across CRMs and payment providers. One NLP build required domain-specific terminology mapping — similar in spirit to how a speech pathologist structures clinical language data — which I adapted into the classification layer; an unusual reference point for a python developer aws build, but the kind of detail that makes a model usable in the field, not just accurate on paper. 🌍 ROLES CLIENTS HAVE HIRED ME FOR I've been booked as a web developer for full rebuilds, a php developer for legacy fixes, a react developer for interface work, a wordpress developer for CMS builds, a mobile app developer for companion apps, and a blockchain developer for a wallet-integration feature — plus the occasional data scientist role when the analysis mattered as much as the code. Whatever the label, delivery is the same: a full-stack web developer's ownership of the whole product, backed by a laravel and php background for teams migrating off older systems. ⚙️ TECH STACK Python · Django · Flask · FastAPI · React · Node.js · JavaScript · Java · PostgreSQL · MySQL · Docker · Git · HTML5 · CSS3 · Bootstrap · jQuery · WordPress · Angular · Software Architecture & Design · REST API · Data Scraping 🚀 Looking for a Python Developer who thinks like an AI Developer and builds like a Full Stack Developer?
