2025 - Present · part-time

• Built the backend and AI workflow for a platform that turns plain-English hardware descriptions into schematics, PCB layouts, firmware, BOMs and fabrication files.
• AI proposes designs, fixed checks test electrical and physical constraints, and people review the result.
• Built a minimal 3-tool interface (instruct, autonomous_instruct, check) so external AI agents can operate a robot without low-level hardware commands.
• Integrated Digi-Key, Mouser, LCSC, JLCPCB and PCBWay; grew to 4,000+ users with enterprise letters of intent.
• Accepted into Antler with RAVN.

Jun 2024 - Feb 2026

• Built an AI cold-email SaaS solo at 17: Gmail/IMAP inbox connections, LLM personalisation with a template fallback, and throttled multi-step campaigns under per-account sending limits.
• Built a self-healing loop that checks every mailbox every two hours, refreshes tokens and flags the ones that need the user to sign in again.
• Grew it to 300+ active users on a credit-based freemium model, then shut it down when platform verification costs made it unsustainable.

• Built the verification layer that checked every AI-initiated banking operation against fixed logic before execution.

• Shipped to Bunna Bank as a paying client, reaching 1,300 users at peak.

Aug 2023 - Mar 2024

• Built an affordable coding-education platform for students from underfunded communities, and taught on it.
