Project details
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.

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.

Seeking Expert Developer for AliExpress & eBay API Integration
Unfortunately, this was not a positive experience. The project was sold as a full automation system, but quickly shifted into a vague "discovery phase" without delivering real progress. Despite many meetings and messages, the actual work amounted to little more than planning docs — no working product, no automation, and no core features built.
After weeks of waiting, I was presented with a basic manual input field, which fell far short of the promised functionality. I had to open a dispute to recover my payment, and Upwork ultimately ruled in my favor, confirming the hours did not qualify under their protection.
Based on my experience, I believe the team never had a clear or committed plan to build the full system as initially agreed.

Job Success
Chornomorske, Ukraine - 2:51 am local time
With 15+ years in full-stack web development and 250+ delivered projects, I work as a founder and technical lead. I partner with clients in logistics, B2B services, and eCommerce to build custom CRM platforms, internal business systems, management systems, and operational software that reduce manual work, improve visibility, and give teams a more reliable way to run day-to-day operations.
I'M A GOOD FIT IF
• Your team still relies on Excel, Google Sheets, shared documents, or email threads to manage important workflows;
• Your current SaaS platform, CRM, ERP, WMS, or internal business system has become hard to change and needs stronger technical direction;
• You need a reliable full-stack development partner for API integrations between your internal systems and marketplaces, shipping carriers, payment gateways, or AI services.
WHAT I BUILD
• Full-stack development for custom B2B SaaS platforms, CRM solutions, and internal operations tools;
• Logistics systems and fulfillment software, including TMS, route planning, dispatcher dashboards, cargo planning, warehouse management views, and inventory workflows;
• System integrations, business process automation, and AI-powered automation that keep data in sync and reduce repetitive manual work.
Recent examples include a TMS for 3PL and eCommerce fulfillment, a multi-source marketing analytics platform, and an AI-assisted translation workflow system.
HOW I USUALLY WORK
• Review your workflows, constraints, and required integrations, then define a clear scope and milestone plan;
• Deliver iteratively with demos, staging, and QA before release;
• Support stabilization, handover, documentation, and further improvement after launch.
My full-stack development work usually covers backend architecture, frontend implementation, databases, API integrations, deployment, and long-term system support.
CORE STACK: Laravel/PHP, Node.js, Vue, React, TypeScript, MySQL/PostgreSQL, AWS, Docker, REST/GraphQL, and integrations with marketplace, payment, shipping, and AI APIs.
If you already have a project in mind, send me 3 - 5 sentences about your current workflow and what you want to improve. I'll reply with initial fit, a possible direction, and a rough budget/timeline range.
