Full-Stack Developer to Build Modern SaaS MVP Worked with Join.To.IT on a fixed-price MVP project. Final milestone was auto-released by Upwork before I had the opportunity to test or approve the work. The agreed scope (QA, UX Polish, Final UAT, Payments) was not fully delivered. An independent technical audit of the GitHub repository confirmed ~68% completion, with several features either non-functional or never integrated into the application. Currently in mediation with Upwork regarding a partial refund.

Mobile Cross Platform App Refinement and Deployment I had a good experience with Oleksander and the team like Ostap. They helped me with my React Native/Expo App and got it into the app stores. I appreciated their communication despite the time zone differences. Great team to work with, would recommend.

Mobile App UI/UX Designer & React Native Developer for AI App (SongByrd V2) This is the second project I've completed with Oleksandr and his team at Join.To.IT, and once again they delivered top-notch work. The project was a technically demanding build using React Native, Firebase, RevenueCat, OpenAI, Spotify API, etc. all working together and they executed every piece cleanly. Communication was clear throughout, the timeline was respected, and the final product came in on budget and matched the vision we mapped out at kickoff.

Kyiv, Ukraine - 12:00 am local time
🔥I help startups and growing businesses build fast, scalable web and mobile apps using Python, Laravel, React Native, and React. I work as a full stack developer who can take a product from idea to production with clean code and predictable delivery. If you need a reliable web developer for modern UI work and a strong mobile app developer for iOS/Android builds, I can cover both while staying hands-on as a full stack developer focused on performance, UX, and maintainability. I’ve delivered solutions for founders who need speed now and stability later, and I communicate clearly at every step.🔥

🚀I also lead a web development team, Join.To.IT from Kyiv, Ukraine as co-founder and CEO. We have multiple Laravel developers (Senior PHP and Custom PHP MySQL), Python (Django), and JavaScript (React, Vue, React Native) developers. If your project needs a dedicated mobile app developer, we can staff that role quickly, while I stay involved as a full stack developer to keep architecture, delivery, and communication aligned. When the UI scope grows, a senior web developer can join the project while I remain the full stack developer responsible for end-to-end quality.🚀

I’m an experienced Laravel engineer, React engineer, Vue engineer, and React Native engineer with 14 years of production experience. As a full stack developer I can build backend APIs, admin panels, dashboards, and customer-facing apps, and as a web developer I pay attention to UI details that improve conversion and retention. I’ve completed a wide range of successful projects, from MVPs to large systems with long-term maintenance and continuous improvements.

My skills:
React
React Native
Software Architecture & Design
Laravel
Python
Full-Stack Development
API Development
JavaScript
PHP
Web Application Development
Node.js
AWS Development
MySQL
Mobile App Development
Django
WordPress
HTML5
Tailwind CSS
Web Design
API Integration

Stack of technologies we use:
✅ HTML/CSS, Bootstrap, Tailwind
✅ JavaScript (React, Vue, Node.js, Express, AdonisJS, Nuxt)
✅ React Native for cross-platform mobile delivery
✅ API integrations (Stripe, PayPal, Twilio, TextMagic, Xero, DocuSign, Google Maps, Meta APIs, and more)
✅ API development (Laravel, Node/Express, Firebase, Python/Django, Go, REST, GraphQL)
✅ PWA (Progressive Web App)
✅ Databases: MySQL, PostgreSQL, MongoDB, DynamoDB, Elasticsearch
✅ Infrastructure: AWS, DigitalOcean, Firebase, Supabase
✅ DevOps and administration: LAMP, CentOS, Ubuntu

As a full stack developer, I connect the front end, back end, and infrastructure so releases are smooth. When the scope includes native-like UX, I can collaborate with a mobile app developer without slowing down the API roadmap, and a web developer can refine UI flows while we keep the backend stable.

You can hire me as a full stack developer for full ownership, or extend the team and keep me as the full stack developer leading architecture and delivery. If timelines are tight, add a mobile app developer to parallelize mobile features, and add a web developer to accelerate dashboards and front-end work.

Our team has already worked in such industries as:
✅ Marketplace
✅ E-commerce
✅ Travel and Hospitality
✅ Custom ERP (Enterprise Resource Planning)
✅ ChatGPT integration (LLM model in your website front end)
✅ Automotive (car inspection, automotive ERP, car sharing, rental, selling)
✅ Social media (Tinder-like networks, short video platforms, communities)
✅ Sales (CRM systems for sales teams, retail, hospitals, sales departments)
✅ Sport (gym management systems, trainer platforms, fitness apps, club portals)
✅ Legal (document automation, AI-assisted legal processing)
✅ Healthcare (clinic management, booking, mental health software)
✅ Education (LMS, automated training, coaching marketplaces)
✅ Finance (fintech platforms, investment platforms, bank API integrations, calculators)
✅ Manufacturing (shop floor management and automation)
✅ Human resources (HRM systems)
✅ Digital marketing (Meta, Facebook/Instagram, TikTok, Google APIs, analytics)

In our work history you’ll find successful products built with Laravel, PHP, JavaScript, MySQL, React, Vue, WordPress development, Web Development, Full Stack development and React Native, plus multiple systems built with Python (Django, Flask, FastAPI). I also use LLM capabilities and AI APIs (including OpenAI integrations) when they genuinely improve the product experience.

We have 65 senior developers across PHP, JavaScript, MySQL, Python, Go, and Node.js. As a full stack developer, I can jump into an existing codebase, stabilize releases, fix bottlenecks, and plan the next iterations.

Don't hesitate to get in touch with me for further details and fruitful work.

Best regards,
Oleksandr
CEO, JoinToIT
