Brief Professional Profile

I am a backend / fullstack developer with a strong focus on applied automation, integrations, internal portals, CRM/ERP-like systems, and complex business logic design. Over years of work, I have grown from developing discrete modules and internal tools to a level where I design integration circuits, deliberate on the architecture of complex systems, stabilize troubled projects, and lay the foundation for product growth in future versions.

Core Specialization

  • internal portals, CRM, ERP-like systems, and administrative panels;
  • integrations: 1C ↔ Web ↔ CRM ↔ API ↔ external services;
  • production calculations, specifications, tasks, and technological scenarios;
  • educational systems, personal portals, dynamic forms, and analytical dashboards;
  • medical systems with equipment, logs, and processing stages;
  • corporate portals and CRM circuits on Bitrix24;
  • real-time and highload platforms with queues, WebSocket, caching, and distributed integrations.

Technical Stack

  • PHP 7/8
  • Yii2
  • Laravel
  • CodeIgniter
  • Node.js
  • TypeScript
  • React
  • Next.js
  • Vue

  • REST API
  • WebSocket
  • Docker
  • Bitrix24
  • CI/CD

My Growth

Innova Systems

During this phase, I worked deeply on applied automation, production modules, calculations, ERP logic, and R&D directions. Here, my foundation in domain logic, integrations, and internal systems was formed.

Prime Systems Group

Here, I grew toward architecture and technical leadership. I took over an unstable project, restored its key circuits, and then became the lead developer and Technical Lead, responsible for backend, real-time integrations, and system stability.

DataSoft

In this phase, I strengthened my role as an architect of integrations, performance, and internal platforms. I design exchanges between 1C, personal portals, CRM, and external systems, stabilize APIs, cache, queues, transactional scenarios, and perform security audits and architectural control of critical modules.

Key Project Directions

  • furniture production: specifications, calculations, CRM/ERP, inventory, internal portals;
  • education: residency personal portal, electronic journals, dynamic forms, dashboards, MAX solutions;
  • medicine: instrument processing system with API and hardware circuit;
  • corporate CRM and internal portals: Bitrix24, contract circuits, productivity, cron, and webhooks;
  • fintech and highload: crypto platform with backend, real-time, queues, and trading circuit;
  • my own technical libraries and plugins for Yii2.

What Characterizes Me

  • I can quickly enter complex subject areas;
  • I translate real-world business processes into domain models, APIs, and interfaces;
  • I can perform expert analysis of systems, integrations, and business processes before active development;
  • I understand infrastructure, network security, and can perform audits of a business's IT structure;
  • I can stabilize troubled projects after other developers;
  • I design integrations to reduce chaos, duplicates, and data discrepancies;
  • I think about performance, security, consistency, and scalability;
  • I am moving toward the role of developer-designer and integration architect of application systems.
