- AI voice agents — built Wavva's AI front office: Twilio telephony + LLM orchestration, AI scheduling, automated SMS/email follow-ups, per-tenant billing with Stripe.
- Test automation research — reverse-engineered Healenium's self-healing engine from OSS bytecode (heuristic LCS + Levenshtein scoring, exact weights) and built Mimic's 4-signal healing engine on top of that research.
- Full-stack SaaS — multi-tenant Next.js + PostgreSQL platform: role-based access, seat limits, trial/overage billing, i18n, Playwright regression suite (83 scenarios).
- Vision pipelines — Wavva Lens: SAM 3.1 segmentation wired into a photo → quote → booking workflow.
