Stripe Connect V1 → V2 Migration
Fintech Marketplace · Financial Services
4 weeks (core: 14 days)OutcomeDual-API coexistence with zero payment failures during transition.
Core API migration completed in 14 days; full rollout in 4 weeks. Implemented dual-webhook coexistence pattern allowing V1 and V2 endpoints to operate simultaneously during merchant-by-merchant migration. Feature flags controlled traffic routing per merchant ID.
Failure mode: Early merchants experienced brief webhook delays during cutover windows, mitigated with exponential backoff retry logic.

MLS Data Integration
Real Estate Platform · Real Estate
3-day deployment sprintOutcomeLLM data-mapping agents collapsed a 12-week integration timeline.
Claude Code agents automated schema alignment across 47 disparate MLS data formats and generated unified transformation logic. Human review handled the ~3% of edge-case listings. Up to 90% reduction in manual data entry vs traditional field-by-field mapping.
Failure mode: SOC2 compliance and audit logging deferred to Phase 2. Edge-case listings still require human review.

3 days (scaffold only)OutcomeJWT/RLS scaffolding deployed, ready for feature development.
Auth, RBAC, and Supabase Row Level Security enforcing tenant isolation from day one. Infrastructure only — no business logic. Client engineering team built features on top over the next 6 weeks.
Failure mode: Initial RLS policies were overly restrictive; two iterations required before the feature team could proceed.

Aggregates 12 public intelligence sources with LLM-powered entity extraction and relationship mapping. Analyst dashboard provides threat timeline visualization and exports. Microservices on Kubernetes with Redis pub/sub for real-time updates.
Failure mode: SOC2 compliance and multi-tenant billing deferred to Phase 2. Current deployment is single-tenant only.

Ongoing developmentOutcome110-agent SMB finance platform: invoices, reconciliation, compliance.
OpenClaw-native SMB finance platform built with Bun + Hono backend, React dashboard, Supabase with RLS/RBAC. Agents operate in specialized clusters: intake (15), validation (25), reconciliation (30), reporting (20), compliance (20).
Failure mode: Reconciliation agents occasionally flag false positives on currency conversion edge cases (~2%), routed to a human review queue.

Ongoing developmentOutcomeSingle implementations utilizing upwards of 50 concurrent worker nodes.
Multi-agent orchestrator: 1 CEO agent (LangGraph) delegates to 10 sub-orchestrators (Claude Agent SDK), each managing 5 specialized workers across six business layers. This is not '50 production agents' — it's concurrent worker capacity within hierarchical orchestration.
Failure mode: Orchestrator timeout on complex multi-hop reasoning chains exceeding 120 seconds, mitigated with chain-of-thought chunking.
