Mykhailo Yarytskyi

Senior backend and full-stack engineer focused on production-grade systems, integrations, and operational reliability.

GitHub | LinkedIn | Portfolio | Email

I build API-first services and platform components with clear domain boundaries, predictable workflows, and maintainable delivery pipelines. I focus on systems that are technically solid and product-useful, from architecture decisions through day-to-day operations.

Core Engineering Scope

  • Backend systems for business-critical workflows, access control, and auditability
  • System design and architecture for services with explicit reliability and ownership boundaries
  • Integration-heavy services (webhooks, normalization, idempotency, retries, delivery tracking)
  • Async and event-driven processing with queues, workers, and replay/recovery flows
  • Data and reporting services with SQL-first modeling, recomputation pipelines, and caching
  • Operational tooling: health/status models, incident/retry workflows, and operator-facing APIs
  • Containerized development and deployment workflows with Docker and Linux

Technology Focus

  • Languages: PHP, TypeScript/Node.js, Go, Java, SQL, Bash
  • Frameworks: Laravel, Symfony, NestJS, Express, Spring Boot, React, Next.js
  • Data and messaging: PostgreSQL, MySQL, Redis, RabbitMQ
  • Infrastructure and ops: Docker, Docker Compose, Linux, Apache/Nginx, CI/CD workflows
  • Delivery patterns: REST APIs, WebSockets, validation and policy layers, testing and quality gates

ops-monitor Operational monitoring and intervention API Demonstrates service-status policy modeling, retry orchestration, incident lifecycle, and audit trails Java, Spring Boot, PostgreSQL, Redis, Docker
linux-infra-lab Linux and infrastructure operations lab Demonstrates reverse proxying, automation scripts, backup/restore runbooks, and service diagnostics Linux, Bash, Apache, Docker Compose, Node.js, PHP, MySQL, PostgreSQL, Redis

Repository Navigation

Selected Professional Work (LinkedIn-backed)

In addition to public repositories, my LinkedIn experience reflects delivery across product, contract, and freelance environments where source code is not always public.

  • Built and maintained full-stack platforms combining React/Next.js frontends with Node.js/PHP backend services
  • Delivered API integrations and workflow automation across content, CRM, and business operations use cases
  • Worked with SQL and NoSQL data models, query tuning, caching, and reliability-focused backend refactors
  • Contributed to CI/CD, containerized environments, release workflows, and cloud-oriented service operations
  • Implemented and supported AEM-based enterprise delivery flows, including component systems, dispatcher/cache concerns, and content operations

Current Focus

  • Backend architecture for systems with strong operational requirements
  • Reliable async workflows (queues, retries, replay, failure handling)
  • Integration boundaries and service-to-service contracts
  • Practical infrastructure and operator-facing reliability tooling
