Yevhen S.

I help B2B companies replace spreadsheets, manual workflows, and disconnected tools through full-stack development, web application development, API integration, database architecture, and workflow automation. I build SaaS platforms, CRM systems, internal business systems, and AI-powered software around real business workflows.

With 15+ years in software development and 250+ delivered projects, I work as a full stack developer, founder, and technical lead at WebMagic. My full stack development experience covers JavaScript, Angular, Database Architecture, and OpenAI API integrations across custom software platforms.

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 reliable API integrations between your internal systems and marketplaces, shipping carriers, payment gateways, or AI services.

WHAT I BUILD:

• Full-stack 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.

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.

CORE STACK:

• PHP/Laravel
• Node.js
• JavaScript/TypeScript
• React
• Vue.js
• Python
• MySQL/PostgreSQL
• AWS
• Docker
• REST/GraphQL
• OpenAI API, and integrations with marketplace, payment, and shipping APIs.

If you’re looking for a full-stack developer for a new or existing product, 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 range.
