Dmytro Lysohor

Senior Software Engineer

Agentic AI · Python · Ruby · Product engineering

I build products, reliable backend systems, and enterprise integrations that make complex work simpler.

9+ years in software engineering, from agricultural technology to Apple’s internal platforms. Based in Madrid, Spain.

Expertise

  • Agentic AI & product engineering

    LLM APIs, retrieval-augmented generation (RAG), and Model Context Protocol (MCP) integrations for agentic workflows. Turning technical possibilities into useful product features.

  • Python, Ruby & full-stack engineering

    Web applications, REST APIs, and background processing with Ruby on Rails and Python/Django. Full-stack development with JavaScript and React, backed by PostgreSQL and MySQL.

  • Enterprise integrations & modernization

    Connecting third-party services, automating manual workflows, and improving legacy systems. Experience across enterprise platforms, agricultural technology, and education.

  • Performance & technical leadership

    SQL optimization, faster CI/CD, and delivery from planning to production. I’ve led a six-person engineering team and mentored engineers through code reviews and pair programming.

Selected work

Apple Marcom

via Grid Dynamics

Workshops, Apple’s internal platform for global localization, creative production, and staffing. Led feature delivery, improved SQL workloads, and automated file ingestion.

  • CI checks: ~3 hours → ~15 minutes
  • File ingestion: hours of manual work → under 5 minutes
  • Application performance: diagnosed and resolved bottlenecks in Workshops using Splunk and Datadog, cutting affected page load times by up to 90%.

Cropio

Led the R&D integration team for an agricultural technology platform. Built machinery integrations and modernized services across Ruby on Rails and Python/Django.

Introduced team practices that nearly doubled delivery volume, and added automated tests and background processing with Sidekiq and Redis.

Travel & education platforms

Built REST APIs for Vimapp, a location-based recommendation app, and backend features for Colegio Pro-Tijuana’s education platform at CiLabs.

Automated student onboarding, exams, and reporting, and integrated Conekta payments for tuition and fees.
