Technical Lead at Clear Cloud One building production AI billing systems, Salesforce packages, and deterministic MCP audit agents.

At Clear Cloud One, I built and shipped Sophia, a production AI billing and accounting assistant for Salesforce users. It connects client Salesforce orgs with the Anthropic API through AWS Lambda, API Gateway, and FastAPI, with a human-confirm gate for every write.

I also designed the agent-hub architecture now standard across the company: read-only MCP audit services on AWS that check live project data. After a vendor agent hallucinated, I made the core rule explicit: live facts come from fresh API reads and deterministic code, not model judgment.

For Clear Cloud One, I engineered a Salesforce billing package that syncs time entries, generates invoices, calculates commissions, and posts to an ERP. I also investigated accounting data for winery and law-firm clients, corrected $94.6k of misbooked journal entries, and built an as-of inventory report.

Earlier, at WhapyDev, I built a financial broker platform spanning backend, MT5 server, web and mobile apps, and administrative CRM. At NexFy, I built a CRM SaaS with WhatsApp Business integration, AI, and smart notifications; I also build personal projects including a phone-to-terminal control surface for Claude Code sessions.
