Work History

Founder & Sole Engineer: QAI

Quinto Sales Inc.
04.2026 - Current
  • Built and shipped a full-stack lead-intelligence platform end to end; Architecture, backend, front end, prompts, data layer, and deployment-with no team, no budget line, and no dedicated build time. In production and in daily use by a 13-person BDC against live Elead CRM leads.
  • Designed a two-model architecture that splits reasoning from bookkeeping: a frontier model generates rep-facing strategy, a small fast model handles silent structured logging. Instrumented per-call token accounting and cut cost per game plan through prompt-cache restructuring and effort tuning.
  • Migrated the data layer from Google Sheets to Supabase/Postgres behind a flag-gated dual-write seam, cutting over with zero downtime and no loss of the historical corpus.
  • Built the classification and routing layer that scores every lead by status and intent, detects behavioral signals (two-way conversation, appointment set, financing turndown, bought elsewhere, opt-out), and routes exceptions into manager review-surfacing misclassified dead leads per month that the CRM had written off.
  • Ran a read-only audit of the live prompt path that exposed dead branches, contradictory rules, and a routing mechanism that was computed but never used; Rebuilt around it. Chose deterministic code over agentic loops in the customer path on latency, cost, and blast-radius grounds.
  • Set BDC-sourced sold units as the single north star and rejected vanity metrics (appointment counts) that staff compliance made unreliable. Instrumented reply rate as a fast steering signal validated against the slower sold-unit outcome.
  • Proficient in utilization of Node, Vercel serverless, Supabase/Postgres, Anthropic API, GitHub PR workflow

General Sales Manager: Central Buick GMC

08.2022 - Current
  • Grew the store from 30 units/month to a peak of 108, holding 150%+ of objective on new units across the Southeast region for four straight years.
  • Own the full funnel: BDC lead response and appointment setting, floor traffic, needs analysis, demo, negotiation, desking, trade appraisal, and F&I structuring-then carry the same deal through the remote and digital retailing path.
  • Structure deals at ~$3,900 per copy front and back, excluding dealer fees.
  • Hire, train, schedule, and manage a 13-person BDC plus the sales floor; Independently built the team that sustained the numbers above through multiple market cycles.
  • Instituted the follow-up accountability process now governing lead distribution: Reps clear their task queue to receive new internet leads, with aged leads recycled through manager review.
