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
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
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
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
By Kris Drouet, Engineering Executive, in partnership with KORE1 A slow engineering org has a systems problem. A tired one has a capacity problem. Both produce the same flat delivery chart, and the treatments are opposite, which is why guessing costs you a quarter. The distinction is not how much the team ships. It is … Read more
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
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
By Kris Drouet, Engineering Executive, in partnership with KORE1 An engineering decision-rights framework is a one-page map that names who owns each kind of decision before it comes up, so calls get made at the right level instead of in a hallway or in your inbox. It is the third layer of the Clarity Stack, … Read more
By Kris Drouet, Engineering Executive, in partnership with KORE1 Before you sign an AI vendor contract, run the pilot through four gates. Proof, integration, exit, and kill. Each one is a go or no-go you clear before the signature, not after. Clear all four and the pilot has a real shot at production. Miss one … Read more
By Kris Drouet, Engineering Executive, in partnership with KORE1 A point-to-point integration refactor replaces direct service-to-service calls with decoupled connections, usually async messaging or an event backbone, so one slow or changing system stops breaking every other system wired to it. Sequence it right and you get lower latency and, more to the point, a … Read more
