When to Buy and Then Build On Top: The Most Underused AI Pattern in Mortgage Tech

Engineering executive weighing how much of a vendor AI platform to trust versus build custom on top

By Kris Drouet, Engineering Executive, in partnership with KORE1 Buy the vendor’s AI for the seventy percent every lender needs, document intake, underwriting signals, compliance logging, and build custom only at the one exception queue that is actually yours. Most engineering leaders pick one extreme or the other. The pattern that actually works sits in … Read more

Fintech Engineering Velocity Without Audit Pain: 3 Patterns That Actually Work

Fintech engineering VP who keeps release velocity high through audits with a risk-tiered change process

By Kris Drouet, Engineering Executive, in partnership with KORE1 Fintech engineering teams keep velocity through an audit by making evidence a byproduct of the pipeline, tiering changes by risk instead of reviewing everything equally, and documenting a break-glass path before they need it. Three patterns. I have shipped under all three, auditors have signed off … Read more

The Real Cost of a Synchronous API in a Pub/Sub World

Empty conference room at dusk with a whiteboard of boxes and arrows after an architecture review

By Kris Drouet, Engineering Executive, in partnership with KORE1 A synchronous call inside an event-driven system costs you the product of every dependency’s availability, the worst tail latency anywhere in the chain, and the retry load of every client sitting above it. Three numbers. You can compute all three in an afternoon from data you … Read more

The Sprint Plan That Acts Like a Contract: How to Treat Estimates as Informed Commitments

Empty engineering sprint planning room with a blank whiteboard and orange accent wall before a planning session

By Kris Drouet, Engineering Executive, in partnership with KORE1 An estimate becomes an informed commitment when it names its assumptions, carries a range instead of one date, and comes with a standing right to renegotiate scope the moment an assumption breaks. An aspirational guess carries none of that. It carries a date and a hope. … Read more

The Vendor Demo Trap: Why Your Best Engineers Can’t Tell If an AI Pitch Is Real

Two engineering leaders reviewing an AI vendor proposal on printed documents in a conference room

By Kris Drouet, Engineering Executive, in partnership with KORE1 Your best engineers cannot reliably evaluate an AI vendor demo, because the demo is a controlled performance and their own judgment about AI is measurably unreliable. In a 2025 randomized trial, experienced developers ran 19% slower with AI tools while believing they had run 20% faster. … Read more

The Coaching Conversation That Salvages a Promoted IC Before They Wash Out

Director and newly promoted engineering manager in a one-on-one coaching conversation at a small table

By Kris Drouet, Engineering Executive, in partnership with KORE1 Coaching a new engineering manager works when you name the specific behavior, hand back the decision they are avoiding, and set a check-in date. A postmortem explains why someone failed. A coaching conversation happens early enough to change the outcome. The gap between those two meetings … Read more

API Architecture for Mortgage Tech: 4 Patterns That Survive Volume Spikes

Engineering executive discussing mortgage tech API architecture patterns with two software engineers in a modern fintech office

By Kris Drouet, Engineering Executive, in partnership with KORE1 Mortgage tech API architecture survives volume spikes when four patterns hold: asynchronous intake, per-vendor bulkheads, a separated read path, and replayable writes with deliberate load shedding. Rate moves are not gradual. Volume arrives in days, not quarters, and the parts of your stack you do not … Read more

What Mortgage Tech Engineering Leaders Learn the Hard Way About Compliance

Two engineering leaders reviewing printed mortgage compliance documents in a modern fintech office

By Kris Drouet, Engineering Executive, in partnership with KORE1 The hard lesson in mortgage tech is that compliance is not something your legal team bolts on after you ship. It lives in your database schema, your disclosure timers, and your deploy pipeline. The engineers who learn that early stop generating audit findings. The ones who … Read more
