Ilias Martis

I’m a Senior Backend / Full Stack Engineer with 15+ years of experience delivering high-performance, scalable web and backend systems. I specialize in secure, highly available solutions for finance and blockchain, including transaction processing, security, and compliance requirements, and I’ve integrated AI/LLM capabilities (Claude, Gemini, OpenAI, Ollama, self-hosted LLMs) to support real workflows.

On recent projects, I’ve maintained and scaled a corporate web platform using Next.js, React, TypeScript, and headless CMS integrations (e.g., Strapi), focusing on SEO, performance tuning, UX improvements, refactoring, and stability through testing and continuous monitoring. Earlier, I built and maintained high-availability backend microservices for a large crypto exchange—integrating blockchain nodes, implementing event-driven processing, engineering deposit/withdrawal pipelines with approval flows and segregated wallet structures, and strengthening observability for incident analysis. I bring a broad foundation from REST API and database-driven optimization (PostgreSQL, MySQL, MongoDB) to earlier full-cycle web work (WordPress/WooCommerce) and system administration with Linux/Windows and CI/CD.
