Insights · Engineering essays

Field notes from the studio.

Short, technical writing on the things we run into shipping production software. Nothing recycled, nothing AI-generated.

Engineering essays, not thought leadership.

Every post is a problem we hit on a real engagement and the pattern we used to solve it. No vendor primers, no "10 trends" round-ups.

AI & LLM systems

Evals, RAG, fine-tuning, agentic patterns. Things that work and things that don't in production.

Architecture & trade-offs

The decisions you can't undo later. Postgres vs. specialized stores, monolith vs. services, sync vs. event-driven.

Delivery practices

Feature flags, observability, deploy automation, postmortems. The boring work that makes the rest possible.

Hiring & team-building

What we screen for, how we onboard, what makes a senior engineer at WAMO Labs different from one anywhere else.

Performance & cost

p95 latency, infrastructure cost per active user, runtime efficiency. Numbers we hold ourselves to.

Field notes

Short, specific things we ran into this quarter. Untheorized. The kind of writing engineers actually read.

Engineers shipping the work, then writing about it.

Every essay is by-lined. Every author has hands on the code they're describing. No ghostwriters, no marketing-team rewrites.

Hamid Khan, Founding partner

Architecture, sales engineering, the founder-engineer perspective. 11 years of shipped product across FinTech and HealthTech.

Engineering principals

The senior engineers who run engagements. Topics that matter: AI evals, multi-tenant architecture, delivery rituals.

Domain specialists

HIPAA, SOC 2, PCI DSS, payments rails. The people who actually take clients through certification, writing about how.

Guest engineers

Occasional posts from clients and friends-of-the-studio. Different perspectives, same bar for substance.

Things we'd rather not say.

Some content categories are intentionally absent. They waste your time and ours.

Listicles & "X tools you need"

If a post can be replaced with a Google search, we haven't earned your attention. We write only when we have a take.

Generic AI primers

You can read the OpenAI blog. We write about specific patterns we've shipped, not what an LLM is.

Recycled vendor content

If AWS, Vercel, or Vercel's competitors already published it, we don't republish a variant.

AI-generated drafts

Every post is written by a human who ran the code. The voice is real, the typos are real, the takes are real.

Stay in the loop

One letter, monthly

A round-up of what we shipped, what we learned, and what we're building next. No filler.
