You will get a safe Angular legacy upgrade or migration plan
Top Rated
Project details
I will help you plan or start a safe Angular legacy upgrade.
This project is useful if your Angular application is outdated, hard to maintain, blocked by old dependencies, difficult to upgrade, or risky to change without breaking production.
I will review the current Angular version, dependencies, build setup, Angular Material usage, RxJS patterns and possible breaking changes. Depending on the package, I can prepare an upgrade roadmap or implement a limited first migration step.
The goal is to modernize the application gradually and safely instead of rewriting everything at once or making risky upgrades without a plan.

React Native Developer (TypeScript) for Real Estate Expense Calculator
Working with Artem was a great experience. He developed our cross-platform Real Estate Expense Calculator app from the ground up using React Native and TypeScript, and the result exceeded our expectations.
The app works perfectly on both iOS and Android, is super fast, and looks exactly like the Figma design. Artem took care of everything, from clean code and smooth REST API integration to publishing on the App Store and PayMarket.
Communication was always clear and professional, and he was very responsive to feedback. I highly recommend Artem for any React Native / TypeScript project, he’s reliable, skilled, and easy to work with.

Job Success
Warsaw, Poland - 5:28 pm local time
I build AI automation and support systems for businesses operating under EU rules (GDPR / EU AI Act). Most recently I shipped an AI patient-support assistant for a network of healthcare clinics in Belgium - multilingual, on web and WhatsApp, with appointment booking and live-agent handoff.
Mostly React, Next.js and Node.js: SaaS products, CMS-driven platforms, dashboards and business-critical web apps.
What I can help with:
→ AI support agents: RAG pipelines over your own docs, grounded answers, live-agent handoff
→ AI agents and automations: OpenAI / Claude, LangChain, vector search, WhatsApp and Telegram
→ Payload CMS development: custom collections, access control, Next.js integration, migrations
→ Statamic and headless CMS setup, cleanup or rescue of an existing install
→ Next.js / React apps: SaaS dashboards, admin panels, business-critical web apps
→ Node.js APIs, backend logic and third-party integrations (Stripe, CRM, Google Sheets)
→ React Native apps for iOS and Android, including App Store and Google Play release
→ Website speed, Lighthouse and Core Web Vitals optimization
→ Legacy rescue: AngularJS upgrades, refactoring, taking over abandoned codebases
→ Technical audit with a clear roadmap before implementation
Why clients work with me:
• 10+ years of full-stack development experience
• $100K+ earned on Upwork
• 100% Job Success
• Top Rated - consistently top-ranked talent on Upwork
• Strong experience with long-term projects, legacy systems and existing codebases
• I work async, communicate clearly and can take tasks from investigation to implementation
• Comfortable working with US, UK, EU and CEE clients
Recent work:
▪ Built a real estate platform with Payload CMS + Next.js and an AI listing parser (OpenAI)
▪ Built an AI support chatbot and CRM with Payload + Next.js + WhatsApp integration
▪ Built Next.js + Statamic CMS websites for business and healthcare clients
▪ Improved performance, forms, tracking and lead flow for existing websites
▪ Upgraded a large legacy Angular application to a modern version
A good first step is usually a small technical audit or fixed-scope rescue sprint. I identify the highest-impact issues, explain what is worth fixing first, then continue with implementation or ongoing hourly support.
Stack: Next.js, React, React Native, Node.js, TypeScript, Payload CMS, Statamic, Supabase, PostgreSQL, OpenAI, Claude, LangChain, RAG, vector databases, WhatsApp Business API, Stripe.
