Work
Systems built around money, risk and machine decisions.
Two tracks: financial systems that keep money correct, and AI systems that make decisions you can defend. Every project starts with an expensive operational problem and ends in working architecture — with the engineering decisions laid out in full.
Track 01
Financial systems, payments & risk
Systems built around money moving correctly: reconciliation, revenue recovery, cash visibility, credit and risk operations, and the evaluation infrastructure that decides whether a model is fit to touch any of it.
Multi-Processor Payment Reconciliation
Transactions, settlements, refunds, fees and payment events from multiple processors normalised into one auditable ledger with automated matching and an exception queue.
Failed Payment Recovery Engine
Failed recurring payments handled by failure type — classification, configurable retry strategies, customer notification and escalation instead of one blunt retry schedule.
90-Day Cash Flow Engine
Cash-position modelling, 90-day forecasting, scenario simulation, runway monitoring and threshold alerts built on operational financial data.
AI Evaluation Harness
Reproducible datasets, repeatable runs, model comparison, metric tracking and explicit decision thresholds — the difference between an impressive demo and a shippable decision.
iOS Risk Data Foundry
Risk-data collection and pipeline infrastructure, with a reproducible feature-engineering benchmark on a public fraud dataset.
Track 02
Applied AI & agent systems
Retrieval, agents and generative pipelines built to the same standard: exact calculation separated from model interpretation, claims bound to evidence, tenants isolated in the database, and an evaluation set that runs in CI.
Graph RAG Account Intelligence
A bounded agent loop — plan, parallel tools, coverage check, safe answer — over exact SQL analytics, hybrid vector search and graph traversal, with tenant isolation enforced in Postgres RLS.
Research Agent for Market Intelligence
Ingestion with content hashing and untrusted-instruction flags, claims classified observed / inferred / conflicting / unknown, and coverage, freshness and source-quality diagnostics.
Strategy & Copy Agent
Evidence-linked strategy contracts and copy assets with deterministic portfolio-coverage checks, optimistic concurrency, exact-version approval and idempotent handoff.
Static Ad Production Studio
Deterministic checks preserve exact copy, safe areas and placement geometry; region annotations create immutable child versions; only a brand reviewer can approve one exact pending version.
Multimodal Video Pipeline
Evidence-backed model routing across current top-tier video profiles, asynchronous attempts with HMAC callbacks and replay protection, one bounded route-aware fallback, and idempotent finalization.
