About me
I’m a hands-on Solutions Architect with 15+ years of experience designing and scaling systems for fintech, ticketing, and SaaS companies. I run an independent consulting practice (https://romaniv.dev), where I combine cloud architecture, AI integration, and pragmatic problem-solving.
My core focus areas: • solution and cloud architecture (AWS, Azure, hybrid environments) • technical and code audits – quick insight into quality, security, and maintainability • AI integrations and automation – LLMs, RAG pipelines, internal GPT tools • architecture optimization and backend development
I’ve worked with clients from the US, UK, and across the EU, helping teams make better architectural decisions, improve reliability, and pass compliance audits.
Feel free to reach out for short consultations, architecture reviews, or technical audits.
