Developer Portfolio

An engineer’s site rather than a designer’s: a terminal hero, thirty legible lines of real code on the home page, the projects, the writing and a CV that prints.

I make slow systems fast, usually by removing something

Ten years on platform and performance. I am at my best on a team that has outgrown its first architecture and still has to ship every week.

Performance

Cutting p95 checkout from 2.4s to 610ms by removing the cache

The cache was hiding a query plan that went quadratic above 400 line items. Invalidation cost more than the reads saved, so the fix was a delete and one index. Six weeks, no downtime, no rewrite.

What the code actually looks like

A fixed-window rate limiter and the one test that matters. Thirty lines is enough to tell whether you want to read the other thirty thousand.

  • Comments explain the decision, not the syntax
  • Fails open, and the test says so out loud
  • No dependency added that a standard library could cover
// Limiter is a fixed-window counter kept deliberately dull.//// A sliding log is more accurate and costs a sorted set per key; at our// traffic the extra accuracy changed nobody's experience and the memory// bill was real. Windows are aligned to the clock so two processes agree// without coordinating.type Limiter struct {	redis  *redis.Client	limit  int	window time.Duration} func (l *Limiter) Allow(ctx context.Context, key string) (bool, error) {	// Bucket in the key, not in a value: expiry then cleans up for us and	// there is no sweeper to get wrong.	bucket := time.Now().Truncate(l.window).Unix()	k := fmt.Sprintf("rl:%s:%d", key, bucket) 	n, err := l.redis.Incr(ctx, k).Result()	if err != nil {		// Fail open. A limiter that takes the site down when Redis blips		// has caused more outages than the abuse it was added to stop.		return true, err	}	if n == 1 {		l.redis.Expire(ctx, k, l.window)	}	return int(n) <= l.limit, nil}

Looking for a principal or staff role

Remote, or Lisbon. Tell me the system and what has stopped working about it. If I am not the right person I will say so in the first reply.

  • I reply to every message within two working days
  • No take-home tests — happy to pair on your real code
  • Available from March

Live components in your current theme — switch routes, or the phone icon to check the mobile layout. Colours are this template’s Phosphor palette, which ships in app/globals.css. High-chroma green on a near-white that is faintly cool, with corners almost square. The palette a terminal would pick if it had to render a CV — and the sharp radius is what separates it from Signal, which uses a neighbouring hue at the opposite extreme.

then

cd developer-portfolio
npm install
npm run dev

The archive contains the whole project — routes, blocks, theme tokens, Tailwind and PostCSS config, tsconfig and a .gitignore. One runtime dependency, and no Hoverlab dependency at all: it is your code from the moment it unzips.

For AI

The component, its props, the design tokens it expects and the command that installs it — as one prompt. Paste it into Claude, Cursor, v0 or ChatGPT and what they build around it will match the rest of the catalog instead of inventing its own system.

Every file is listed. The 26 files in components/ are the blocks the pages import — each one has its own page if you want to read it on its own.

Project files

Everything except the blocks. Opens on app/globals.css — the file that makes the rest look right, since every block styles itself with bg-card and text-muted-foreground rather than literal colours.

app/globals.css
@tailwind base;
@tailwind components;
@tailwind utilities;

/**
 * Design tokens — the Phosphor palette.
 *
 * High-chroma green on a near-white that is faintly cool, with corners almost square. The palette a terminal would pick if it had to render a CV — and the sharp radius is what separates it from Signal, which uses a neighbouring hue at the opposite extreme.
 *
 * This file is the reason a pasted block looks right. Every block and page
 * styles itself with semantic classes — `bg-card`, `text-muted-foreground`,
 * `border-border` — rather than literal colours, so they inherit whatever
 * you define here instead of fighting it. Change a value below and every
 * section in the project moves with it. Change the hue on `--primary` and
 * `--ring` together and you have rebranded the site.
 *
 * Values are bare HSL channels, not `hsl(...)` calls. That is what lets
 * Tailwind compose them with an alpha suffix: `bg-primary/10` expands to
 * `hsl(var(--primary) / 0.1)`, which is impossible if the variable already
 * carries its own function wrapper.
 *
 * Every foreground/background pair below clears WCAG AA (4.5:1) in both
 * themes. If you retune one, check the pair rather than trusting the eye —
 * mid-lightness accents are the ones that fail.
