Payments · Migration

Moving every customer balance to stablecoin rails, without losing a cent

Flash, July 2026. Custodial customer balances moved from the legacy USD ledger onto USDT stablecoin rails — live, with real money, under a regulated operation.

The problem

Every balance is someone's money. The move crossed both a ledger boundary and a custody boundary at once, so the failure modes — double-credits, stranded balances, silently dropped fees — were exactly the ones a money business cannot have. There was no big-bang option a responsible operator would sign off on.

The approach

A per-account state machine with idempotency keys: every step resumable after any failure, and no account can ever be moved twice.
Balances moved as Lightning payments between source and destination accounts — the migration used the same rails customers use, not a side channel.
Canary first: a small batch validated end to end before phased waves covered the full account set.
Per-account locking and attempt tracking; fees captured and automatically reimbursed so customers bore zero cost.
Before-and-after snapshots, dual-ledger reconciliation into the ERP-based banking core, and a rollback path held ready throughout.

The result

5,000+ customer accounts migrated with zero funds lost and every balance reconciled to the cent. The rollback path was never needed.

AI · Operations

The ops team is three contractors and a fleet of AI agents

Flash runs AI-native. Production agents — not chatbots, not pilots — carry real operational responsibility every day.

The problem

A 24/7 money platform generates monitoring, support, and verification work that doesn't shrink when the team does. After launch, the engineering team was deliberately rightsized from twelve to three contractors. The workload had to go somewhere.

The approach

A multi-agent platform where each agent session runs in an isolated container with only the tools and credentials its job requires.
Sensitive actions pass through approval gates — humans approve, agents execute, and nothing credentialed happens silently.
Agents watch live payment flows and post anomalies to the team's channels in real time; support triage and deploy verification run through the same platform.
Built on open-source foundations, with channel adapters that meet the team where it already works — WhatsApp, Discord, Slack.

The result

On its first day live, payment-flow monitoring flagged a critical double-send defect; it was confirmed and reversed the same day. This platform is the reason three contractors can run a regulated money business.

Fintech · Back office

A banking back office on an open-source ERP

The fiat side of Flash — bank accounts, FX, settlement, reconciliation — runs on ERPNext, not on a commercial banking core.

The problem

Cash-in and cash-out across JMD and USD needs double-entry discipline, managed FX spreads, and auditable records. Commercial banking cores deliver that at prices set for banks. A pre-seed company needed the discipline without the price tag.

The approach

General-ledger integration: every platform money movement lands as proper double-entry accounting, automatically.
Split buy/sell FX pricing with automated weekly rate ingestion — no manual rate entry, no drift between what customers see and what the books say.
Bank-account reconciliation and cash-out settlement workflows tied directly to customer records.
Roles and permissions defined in code and reapplied on every rebuild, so environments can't silently drift from the audited configuration.

The result

A full banking back office — GL, FX, reconciliation, settlement — run by the same small team, on open-source software, at open-source cost.

Enterprise · PPM

The PMO product that returned $7.5M a year

Deloitte Consulting · AT&T Wireless. An IT PPM deployment on Clarity, delivered by a three-practitioner team.

The problem

An IT organization at telecom scale runs hundreds of concurrent projects against shared money and shared people. Without one system of record, the waste hides — duplicated work, stalled initiatives, decisions made from stale spreadsheets. The assignment: give AT&T Wireless's IT department a PMO product that made the portfolio visible and governable.

The approach

Clarity PPM as the single system of record — the one place where projects, resources, and spend meet.
Delivered as a product, not a tool rollout: a PMO offering the IT organization adopted, with governance designed around how decisions actually got made.
A three-practitioner team — small enough to move fast inside a Fortune 500, senior enough to hold the room with executives.

The result

A PMO product that generated $7.5M in annual IT-department savings — portfolio visibility turned directly into money.

Consulting · Migration

Retiring Primavera at a global real-estate firm

Performatics Group — my own consultancy · JLL (Jones Lang LaSalle). Selection through migration to adoption.

The problem

JLL's commercial-real-estate PMO ran on legacy Primavera — a system built for heavyweight scheduling, not for how a modern portfolio team works. Replacing a PMO's core system is open-heart surgery: the portfolio keeps running while the system underneath it changes.

The approach

Ran the selection from the PMO's real workflows rather than a feature checklist — landing on Clarizen.
Migrated the PMO's data and processes off Primavera onto the new system.
Drove adoption — the part most migrations skip — so Clarizen became how the PMO actually worked, not shelfware.
Founder-led: as managing partner I sold the engagement, staffed it, and delivered it with a three-practitioner team.

The result

JLL's PMO off Primavera and onto Clarizen — selected, migrated, and adopted — delivered end to end by a three-practitioner engagement.

How the headline claims actually happened.
