I've spent the last 13+ years doing both sides of the job: writing production code and making the architectural decisions that determine whether a product survives real-world load or falls apart at scale. My background runs from hands-on full stack engineering in Java Spring Boot, Node.js and NestJS, through IoT integrations (Tuya, BLE) and AI-assisted development, all the way to leading engineering teams as a CTO and owning complete technical roadmaps. I know when to zoom out and design the system, and when to zoom in and fix the thing that's actually broken. What I bring to a project: - Backend and system architecture: microservices, event-driven design, multi-tenant SaaS, API design (REST, GraphQL) - Full stack delivery: React, Vue.js, Node.js/NestJS, Spring Boot - Cloud infrastructure: AWS, GCP, DigitalOcean, Terraform, Docker - AI-assisted development (Claude Code, Cursor) and AI/voice systems, including a production voice ordering agent built on an MCP server - IoT integrations for smart devices (Tuya, BLE, HDL) I've grown an engineering team from 3 to 25+, delivered systems for UNICEF, UNODC and government agencies, and built platforms now processing 5,000+ e-commerce orders and 1,000+ service orders a day. The portfolio below shows a slice of that range: hosting admin dashboards, AI interview tools, and IoT smart home apps. If you need someone who can design the system, write the code, and take responsibility for how it performs once it's live, that's the work I do.
