Available for new opportunities

Adam Harrington
Staff Engineer

Nearly a decade building quality software for the web — from social-justice platforms and Yahoo-scale traffic to developer tooling and accessible enterprise products. I bring technical leadership, strong opinions on craft, and a genuine curiosity about the people who use what I build.

Engineer first.
But never just that.

I started in frontend because I love the intersection of logic and human experience — a background in Applied Psychology probably has something to do with that. Over time I've grown into a Staff Engineer who owns technical direction, coaches teams, and asks uncomfortable questions when something doesn't serve the user.

I've worked at every scale: scrappy startups with three-person engineering teams, a social-justice campaigning platform, and Yahoo serving hundreds of millions of daily active users. That range shapes how I think about trade-offs.

Right now I'm exploring what comes next — ideally somewhere the mission matters and the engineering culture takes quality seriously.

Frontend Engineering

Deep TypeScript/React across production apps of all shapes. Performance, accessibility, and testability are non-negotiable defaults for me, not afterthoughts.

Architecture & Systems Thinking

Micro-frontend design, monorepo consolidation, bounded contexts. I've untangled legacy codebases and helped teams build for the long haul — not just the next sprint.

Technical Leadership

Cross-team alignment, ADRs, architectural review, and strategy conversations with product and C-suite. I'm consulted regularly by other teams because I frame problems clearly.

Mentoring & Team Culture

I've taught web development at the National College of Ireland and make time for mentoring at every seniority. Growing the engineers around me isn't optional — it's part of the job.

Accessibility

WCAG AA isn't a checkbox for me — it's a design constraint I apply from the start. Several of my employer commitments required it under ADA legislation.

Developer Experience

I have a track record of spotting where teams lose time — in pipelines, processes, or tooling — and making it measurably better. DX work compounds quietly but significantly.

Got a question?
Just ask.

Rather than a wall of CV text, I've built a small AI that can answer questions about my experience, approach, values, and what I'm looking for next. Think of it as a conversation, not an application form.

Try asking something like:

→ What kind of role are you looking for? → How do you approach technical leadership? → Tell me about your Yahoo experience → Are you open to remote work?

Hi, I'm Adam's AI — ask me anything about his background, approach, or what he's looking for next.
What kind of mission-driven companies is he interested in?
AH
Adam is particularly drawn to climate tech, accessibility, civic tech, and healthcare — anywhere the product has a genuine reason to exist beyond revenue...

Let's talk about the right fit.

I'm not firing off applications — I'm looking for a conversation with the right people about the right opportunity. If the mission resonates and you need a senior engineer who can lead and build, reach out.
