Please message me before ordering so I can confirm the scope, required features, and best package.
I work as a Full-Stack Developer building Web Application solutions with structured data, clear user flows, and maintainable code. This project is based on a custom CRM example, but the same approach can fit admin panels, customer portals, task tools, reporting systems, and internal business applications.The example system includes contact records, communication history, task conversion, user access, and dashboard-style views. The goal is to organize business data in one application and make daily work easier to track, review, and manage.
Depending on the package, the work may include API planning, API Integration, Node.js logic, Vue.js or JavaScript interface work, Web Design adjustments, basic Database Architecture, MySQL data structure, testing, source code delivery, and handover notes.

Seeking Full-Stack Developer for AI-Driven Fitness & Wellness Platform (Web & Mobile Integration)
I’ve worked with several developers in the past who needed very exact, step-by-step instructions to deliver what I wanted.
With Yevhen, the experience has been different. I’m able to discuss principles, concepts, and the intended outcome, and he is able to use his own judgement to translate that into a practical solution. He doesn’t just follow instructions mechanically; he thinks through the requirement, challenges where needed, and applies technical understanding to get to the right result.
That makes the working relationship much more effective, especially when building something that is still evolving. It gives me confidence that he understands the bigger picture, not just the individual tasks.

30 minute consultation
The experience was exceptional. From the very beginning, He was focused on truly understanding our main challenge and went above and beyond at every moment to resolve it. The meeting was originally scheduled for 30 minutes, but he took all the time necessary until everything was solved and he did. 100% recommended, we’ll soon be working together.

Job Success
Chornomorske, Ukraine - 1:54 am local time
I help B2B companies replace spreadsheets, manual workflows, and disconnected tools through full-stack development, custom web development, API integration, and workflow automation. As a founder and technical lead, I work directly with clients in logistics, B2B services, and eCommerce to turn complex processes into reliable systems that reduce manual work, improve visibility, and support day-to-day operations.
I'M A GOOD FIT IF
• You need a full-stack developer to build a B2B SaaS platform, custom web application, CRM system, logistics platform, eCommerce solution, or internal business tool;
• Your existing PHP/Laravel, Node.js, Python, Next.js, React, or TypeScript application needs new features, architecture improvements, integrations, or further development;
• Your SaaS platform, CRM, ERP, WMS, or internal system has become difficult to extend or maintain and needs stronger technical direction;
• You need API integration between internal systems and marketplaces, shipping carriers, payment gateways, databases, or AI services;
• You need to modernize a legacy web application or replace manual workflows with custom software.
WHAT I BUILD
• B2B SaaS platforms, custom web applications, CRM systems, and internal operations tools;
• Logistics software for transportation, dispatch, route planning, cargo planning, fulfillment, warehouse, and inventory workflows; eCommerce platforms, marketplaces, and business portals; • Mobile app development with React Native, including iOS development and integration with web platforms and backend systems;
• API integrations, workflow automation, and artificial intelligence features for existing or new products.
HOW I USUALLY WORK
• Review your workflows, technical constraints, and required integrations, then define a clear scope and milestone plan;
• Deliver iteratively with demos, staging, and QA before release;
• Support deployment, stabilization, documentation, handover, and further development.
My work covers backend development, frontend implementation, databases, API integration, testing, deployment, and long-term system support.
CORE STACK: PHP, Laravel, Node.js, Python, JavaScript, TypeScript, HTML5, Next.js, React, React Native, MySQL, PostgreSQL, and API integrations with marketplace, payment, shipping, and AI services.
