About Me

I’m Nick Teryokhin, a Full-Stack Software Architect with over 20 years of experience in IT and software development, helping businesses turn ideas into powerful digital solutions.

I believe technology should empower — not complicate. My mission is to deliver clean, scalable, and secure software that helps businesses grow, adapt, and lead in an ever-evolving digital world.

I specialize in full-stack development, cloud architecture, DevOps automation, UI/UX design, and custom CMS platforms. Every project I deliver is personally crafted with a focus on performance, security, and long-term scalability.

Over the years, I’ve had the privilege to work with startups, global brands, and everything in between — designing booking platforms, building internal tools, and modernizing legacy systems to meet today’s business demands.

At Teryokhin Design, you work directly with me — ensuring your project gets the attention, clarity, and craftsmanship it deserves.

there is nothing impossible

What I Do

I don’t just write code — I craft solutions to real-world problems.

I craft efficient and elegant solutions to complex problems — even when they require unconventional thinking. I use modern technologies and programming languages, and I specialize in building solutions from scratch — from concept to launch.

I create solutions that deliver real business value — whether it’s a web application, a corporate platform, or a mobile product. Below are the types of projects I most frequently work on.

Types of Projects I Work On:
  • SaaS Platforms (Software as a Service) – Subscription-based web services like CRMs, analytics tools, and internal systems.
  • B2B Solutions – Platforms designed to automate and digitize processes between businesses.
  • B2C Products – Web and mobile applications tailored for end-users.
  • E-commerce (Online Stores & Marketplaces) – Solutions for managing product catalogs, orders, and payments.
  • Corporate Portals & Internal Systems – Intranets, document management, inventory tracking, and other internal tools.
  • Landing Pages & Marketing Websites – Fast, responsive, SEO-optimized websites for product and service promotion.
  • Third-Party Integrations & APIs – Connecting payment gateways, logistics systems, CRMs, analytics platforms, and more.
  • Mobile Applications – Cross-platform and native apps with clean architecture and high performance.
  • Digital Transformation Projects – Legacy system migration, process automation, and cloud adoption.
  • Custom CMS & Admin Panels – Tailored content management systems and admin interfaces built around real business needs.
  • WordPress Development – Development of custom WordPress themes and plugins, as well as integration with third-party APIs and billing systems.
  • Graphic Design & Branding – Logo creation, visual identity, marketing materials, and cohesive brand presentation.
  • UI/UX Design – Designing intuitive, user-friendly interfaces with a focus on usability and conversion.

How I Do

Every project starts with understanding your business goals, challenges, and users. From there, I apply thoughtful design, clean code, and scalable architecture to deliver solutions that work.

My approach includes:

  • Deep Discovery – I ask the right questions to understand the business, audience, and goals.
  • Transparent Collaboration – I value open communication and provide regular updates and demos.
  • Design with Purpose – Every line of code or pixel has a reason — whether for usability, performance, or brand impact.
  • Clean, Scaleable Code – I build systems that are maintainable, secure, and ready to grow.
  • Ownership & Reliability – I treat your project like my own and focus on long-term success, not just delivery.
