We just cut our Next.js cold-start times by 61% by moving three data-fetching routes to the edge and caching with stale-while-revalidate.

The part nobody tells you: the win came from deleting code, not adding it. We removed 4 layers of client-side waterfalls and let the platform do the work.

Hiring managers: your job description is a product. Treat it like one.

We A/B tested two versions of the same Senior Engineer role. The rewritten version:

• Led with impact instead of a 14-bullet requirements wall • Named the salary band up front • Cut "ninja/rockstar" language entirely

Result: 3.1× more qualified applicants and 42% mo…

Hot take after 6 months of evaluating LLM agents in production: the model is rarely the bottleneck. Retrieval quality and eval harness design decide whether your product ships.

Our eval suite caught 71% of regressions before they hit staging. Here is the exact loop we run on every PR. #MachineLearning #LLMOps #AI

Northwind Labs is growing the platform team. We are hiring 14 engineers across infra, applied ML, and design systems — remote-first across EMEA and LATAM.

No whiteboard gauntlet. You will pair with us on a real problem from our backlog and get paid for the exercise. #WeAreHiring #RemoteJobs

A design system is not a component library. It is a set of decisions with a budget.

If your team cannot answer "when do we not use the system?" you do not have governance — you have a suggestion box.

We wrote down our escape hatches and contribution rules. Adoption went from 54% to 91% in two quarters. #DesignSystems #UX #ProductDesign

Zero-trust is a migration, not a purchase. We spent 18 months moving 900+ services off flat-network trust.

The unglamorous truth: 60% of the work was identity hygiene and killing shared service accounts. #CloudSecurity #ZeroTrust #Azure

After 4 years leading checkout platform at Shopify, I am opening a new chapter: looking for an Engineering Manager role on a product with real scale and a team that ships weekly.

What I bring: 11 years of backend, 4 managing, a bias for boring reliable tech, and a habit of writing the RFC before the code. #OpenToWork #EngineeringManageme…

Our analytics team replaced 30 ad-hoc dashboards with 6 governed metric trees. Stakeholders complained for three weeks, then stopped asking why the numbers disagreed.

Data trust is a product problem, not a tooling problem. #Analytics #DataEngineering #dbt

We interviewed 40 product managers about how they run discovery. The highest-performing ones spent 3× more time in customer conversations and 3× less time in roadmap formatting.

Roam is not the deliverable. Understanding is. #ProductManagement #Discovery

Ran 24 usability sessions on an AI assistant feature last month. The biggest friction was not accuracy — it was users not knowing when to trust the output.

Confidence, provenance, and undo matter more than another point of benchmark accuracy. #UXResearch #AI #Design
