Designed and delivered the WhatsApp-native LLM content agent including semantic routing and persona, inbound media pipelines, multi-image carousels in correct sequence, and reply delivery hardening. Implemented deterministic semantic control with typed mutation receipts, envelope routing pre-agent boundary, tool-parity adapters, temperature-0 interpretation with latency ceilings and SLO alerts, plus approval-gated publishing and durable scheduling. Automated 208 tests including grounding, review-truth, and correction-proposal suites. Built profile-grounding with correction proposals and an autobiographical claim guard; integrated infrastructure migration to AWS EC2 via Docker Compose, private workflow API, and signed idempotent webhooks; added Anthropic-to-OpenAI fallback routing with request tracing.

Solo-built a driver app and supporting web console using Expo, React Native, Next.js, and Fastify. Shipped production apps to Google Play and Apple App Store. Implemented and proved OCPP 1.6J and OCPP 2.0.1 remote control workflows against simulators, built a Paystack wallet flow with verify-gated crediting and commit-or-roll-back on critical writes, and handled full remote metering and stop-cycle behavior for physical chargers.

Built a WhatsApp-native LLM content agent that uses deterministic semantic control and a 208-test suite. Implemented a typed mutation/verification approach with envelope routing at a boundary between LLM planning and tool execution, plus approval-gated publishing and durable scheduling with cancel-by-identity. Developed verified profile grounding with correction proposals and automated test suites (grounding, review truth, correction proposal). Migrated infrastructure behind a secure tunnel to AWS EC2 using Docker Compose, integrated signed idempotent webhooks, and implemented Anthropic-to-OpenAI fallback routing. Used TypeScript/Node/Express/Prisma with BullMQ/Redis and Supabase, and deployed end-to-end CI with re-hearsed deployments and rollback procedures.
