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.
