Job Success
Lviv, Ukraine - 11:56 pm local time
👋 Hi! I’m a 𝐓𝐨𝐩 𝐑𝐚𝐭𝐞𝐝 Full Stack Developer on Upwork with 100% Job Success and 9+ years of experience building scalable web and mobile products for startups and enterprises, including Rand McNally, Sharpen CX, Magna, Hoermann Intralogistics.
As a Full Stack Developer, I help founders and product teams turn ideas into production-ready systems and scale them reliably over time.
𝐖𝐡𝐚𝐭 𝐈 𝐝𝐨 as a Full Stack Developer
I own products end to end, from early architecture decisions through production delivery and long-term scaling.
I design and develop web platforms and SaaS dashboards focused on performance, stability, and clean architecture, with a strong focus on maintainability as products grow and teams scale.
As a React Developer, I build frontend applications that are structured, predictable, and easy to evolve, using modern component-driven approaches and shared design systems.
As a Mobile App Developer, I deliver production-ready iOS and Android applications, as well as cross-platform mobile solutions using Flutter and Kotlin Multiplatform, ensuring consistent behavior, shared business logic, and seamless backend integration.
On the backend, I design and implement APIs, core business logic, and real-time features that support complex workflows, data synchronization, and high-load scenarios.
I work extensively with relational and NoSQL databases and cloud infrastructure, designing data layers that prioritize performance, reliability, and long-term scalability.
Full Stack development 𝐚𝐩𝐩𝐫𝐨𝐚𝐜𝐡
I design systems where frontend UX, backend performance, and data consistency evolve together, avoiding gaps between product, design, and engineering.
Working with one accountable Full Stack Developer means fewer handoffs, faster decisions, and systems that scale with your business instead of slowing it down.
𝐅𝐥𝐞𝐞𝐭, 𝐥𝐨𝐠𝐢𝐬𝐭𝐢𝐜𝐬, 𝐚𝐧𝐝 𝐦𝐚𝐩-𝐡𝐞𝐚𝐯𝐲 𝐩𝐥𝐚𝐭𝐟𝐨𝐫𝐦𝐬
I specialize as a Full Stack Developer in fleet management, logistics, and location-based SaaS products where accuracy, uptime, and data consistency are critical.
My experience includes building real-time tracking systems, background location processing, offline-first mobile behavior, and map-heavy interfaces used by drivers and operational teams in real-world conditions.
I’ve worked on products where mobile applications replace dedicated hardware, support long background sessions, handle unstable connectivity, and process high-frequency location updates.
As a React Developer and backend architect, I focus on building systems that remain reliable under load and predictable in everyday use across both admin dashboards and driver-facing mobile applications.
𝐓𝐨𝐨𝐥𝐬 & 𝐭𝐞𝐜𝐡𝐧𝐨𝐥𝐨𝐠𝐢𝐞𝐬
I work daily with modern, production-proven technologies across the full stack:
JavaScript for frontend and backend development
TypeScript for scalable and maintainable system architecture
React for building modern web interfaces
Next.js for performance-focused web applications
Tailwind CSS for consistent and maintainable UI styling
Node.js for backend application development
Express.js for RESTful backend services
NestJS for structured and scalable backend architecture
REST API for standard backend communication
GraphQL API for flexible data querying
WebSockets for real-time functionality
PostgreSQL for relational data storage
MySQL for structured database systems
MongoDB for document-based data models
Redis for caching and performance optimization
Firebase for real-time data and authentication
AWS for cloud infrastructure, deployment, and scaling
𝐄𝐱𝐩𝐞𝐫𝐢𝐞𝐧𝐜𝐞 & 𝐬𝐞𝐥𝐞𝐜𝐭𝐞𝐝 𝐨𝐮𝐭𝐜𝐨𝐦𝐞𝐬
Over the past 9+ years, I’ve delivered 100+ web and mobile projects across SaaS, fleet management, healthcare, and consumer products:
Delivered mobile and web products used by thousands of active users across fleet, healthcare, and SaaS platforms.
Built real-time tracking and location-based systems used in daily operational workflows without dedicated hardware.
Shipped cross-platform mobile apps with shared backend logic, reducing maintenance cost and improving release speed.
Developed admin dashboards and SaaS platforms that replaced manual processes and improved operational visibility.
Successfully launched and supported long-term products on App Store and Google Play.
𝐕𝐨𝐥𝐩𝐢𝐬 & 𝐥𝐞𝐚𝐝𝐞𝐫𝐬𝐡𝐢𝐩
I’m the CTO and lead Full Stack Developer at Volpis.
When projects grow, I scale delivery with our in-house design, QA, and engineering team, while staying directly involved as your Full Stack Developer.
You get clear ownership, direct communication, and predictable delivery without losing technical quality.
