Senior software engineer with 18+ years of experience building production software, backend systems, and distributed services. Over the last five years, I have focused primarily on Rust, developing reliable services and applications across healthcare, AI, developer tools, databases, and asynchronous architectures. My experience includes backend design, API development, integrations, and building maintainable software systems.
Since 2010, I have worked as an independent software engineer through my own software consultancy, delivering end-to-end solutions for clients across multiple industries, from architecture and implementation through deployment and maintenance. Over this period, I have delivered more than 40 software projects for 30 clients, including 32 projects via Upwork and 8 through direct client collaboration.
Outside of client work, I explore and develop projects related to AI applications, databases, and developer tools, primarily using Rust and modern backend technologies. I continue to expand my knowledge through technical books, RFCs, documentation, and source code analysis.
