Selected work. Real systems, real numbers.
A selection of recent engagements. Names redacted under NDA where required, metrics shared with permission. Each card links to a full case study.
TheSkinProof — verified-skincare marketplace
A multi-vendor marketplace where every product passes a 4-step verification pipeline before listing. Multi-portal architecture (buyer · seller · admin · warehouse), COD fraud detection, regional payment + courier integrations. 6-week MVP, 750+ tests in CI on day one. Live at theskinproof.com since Q2 2025 — ongoing engagement: continuous feature delivery, reliability work, and platform evolution.
Underwriting platform replatform
Re-architected a brittle Rails monolith into a typed Next.js + Postgres system with auditable decision logs and idempotent loan flows. Cut P95 latency by two-thirds and eliminated rollback incidents.
Multi-tenant listing & inquiry pipeline
From scoped MVP to live marketplace in 6 weeks. Stripe Connect, escrow, agent dashboards, document signing — all production-grade and serving real transactions on day one.
Code rescue: checkout + inventory rebuild
A checkout losing 14% of orders to silent failures. We diagnosed in 4 days, stabilized in 1 week, then ported inventory + payments to a typed event-driven core in 3 weeks total.
Internal ops platform → external SaaS
Took a single-tenant internal ops tool and rebuilt it as a multi-tenant SaaS with RBAC, audit logs, and a public API. Four paying tenants live within two months of go-live.
Reconciliation engine + ledger
A double-entry ledger with strict invariants, idempotent imports, and a reconciliation UI for finance ops. Replaces a spreadsheet workflow that was both slow and unauditable.
Document AI + agent workflow
An agent-facing tool that extracts structured data from listing documents and routes inquiries through a tested decision tree. Founder-reviewed prompts; deterministic fallbacks; full audit trail.
