Evgeny Slepinin

Hi, I'm Evgenii. I am a Full-Stack Web Developer and Systems Architect with 15+ years of experience in IT.

Before fully transitioning to web development, I spent 10 years working as a technical engineer for high-precision medical equipment (Abbott, Werfen). This background gave me a strict engineering mindset: I write clean code, build fault-tolerant architectures (SLA 99.9%), and rigorously test everything before deployment.

I am available for both long-term projects and urgent tasks.

My Core Services:
• Custom Web Development: Building websites and web apps of any complexity from scratch. I specialize in React, TypeScript, Node.js, and HTML/CSS. I also work with CMS platforms (WordPress, Joomla) and set up Server-Side Rendering (SSR) and secure payment gateways (Stripe, PayPal)
• Business Automation & API: Building complex multi-step workflows using Make, Zapier, and n8n to connect your CRM, databases, and apps
• AI & Chatbots: Integrating LLMs (OpenAI, Claude) via API, building RAG-systems (custom knowledge bases), and developing smart rule-based or AI chatbots for Telegram/WhatsApp
• Tech Support & Bugfixing: Urgent server troubleshooting, API conflict resolution, and website speed optimization (Core Web Vitals)

My Tech Stack & Tools: Frontend & Backend: React, TypeScript, Node.js, HTML/CSS
• CMS & No-Code: WordPress, Joomla, Make, Zapier, n8n
• Design & Media: Advanced Adobe CC (Photoshop, Illustrator, Premiere Pro, InDesign)
• Marketing & Analytics: Google Ads, Google Analytics (GTM, CAPI), AEO / SEO microdata (JSON-LD)

I focus on transparent communication and delivering functional products that solve real business problems. Let's discuss your project!
