Thank you for reviewing my service catalog. This document provides a comprehensive overview of the professional services I offer, each designed to deliver measurable business value through modern engineering practices. With over 15 years of experience and 150+ projects delivered to clients worldwide, I bring a pragmatic, production-focused approach to every engagement.

My services span the full spectrum of modern software engineering: from self-hosted AI agents that eliminate recurring API costs, to high-performance backend optimization that scales systems to handle 10,000+ concurrent users, to custom ERP solutions that digitize manufacturing operations end-to-end. Each service is structured with clear deliverables, transparent pricing, and defined timelines so you know exactly what to expect before we begin.

Every service section in this catalog is written for two audiences: business owners who need to understand the value and ROI, and developers or CTOs who want to evaluate the technical approach. I believe in complete transparency — the technologies, architectures, and methodologies I use are all documented here.
