Hi, I’m Bill Siwale, a mid-career software architect with over 10 years of experience, including 4 years coding, focusing on AI and full-stack systems. I specialize in building production-grade solutions on Google Cloud Platform, Vertex AI for computer vision, and Gemini for conversational AI, delivering scalable architectures for industrial IoT, AI-driven sales automation, and enterprise SaaS. I thrive on turning ideas into reliable, testable, monorepo-based products and leading teams from concept to launch. I enjoy combining backend systems (Node.js, TypeScript, PostgreSQL) with modern frontend stacks (React, Next.js) and robust DevOps practices (TDD, CI/CD). I value collaboration and designing secure, multi-tenant architectures that scale across locations and clients.…Hi, I’m Bill Siwale, a mid-career software architect with over 10 years of experience, including 4 years coding, focusing on AI and full-stack systems.
