Portrait of Mauro Carrera, Fractional Head of Development and Technical Director
Available for Web Development projects with werun.dev

I am Mauro Carrera. For over 15 years I have led high-performance WordPress teams and worked directly with Automattic, Elementor and Pressable. I help companies and founders ship better and faster, as a fractional development lead, an independent auditor, or the name behind brand projects.

Ways to work with me

Three ways I create impact

Pick the format that fits you best. My audits and advisory work are independent, never a sales funnel toward execution.

/01

Fractional Head of Development

For companies and growing teams

Integrated part-time technical leadership: roadmap, architecture, hiring, code standards and mentoring. The direction of a senior Head of Dev without the full-time cost. I embed into your operation, prioritize what moves the needle, and leave processes your team sustains on its own once the engagement ends.

/02

Audits and coaching

For founders, freelancers and in-house devs

Independent technical audits, code and performance reviews, and 1:1 coaching. You buy my judgment and my experience. Honest conclusions you can apply with any team. Ideal when you want a senior second opinion before investing, hiring or taking on a big refactor, without committing to anything more.

/03

Brand projects

For large brands, delivered with werun.dev

When a project needs a full team, it comes under my direction and is delivered by werun.dev, my development studio. My standards and oversight, plus a senior team to carry it out. You deal with a single person accountable for the outcome, and behind them a full studio executing to the same bar.

Tell me about your project

The approach

"I lead. werun.dev delivers."
The approach

Leadership backed by recognized credibility

Over 15 years leading multinational teams, directing 20+ developers and QA at 500 Designs and scaling WordPress at Globant.

Recognized where it counts: a case study published by Pressable, selected by Elementor for User Stories, and multiple international awards. That credibility is tied to my name.

How it connects

How we work

4 steps. No magic.

A clear process with no surprises: at every stage you know what happens and you approve it before we move on.

Step 01

Discovery

We fill in a form together that defines the scope: what we'll build, sections, features and goals. All in writing before we start.

Step 02

Design

Visual proposals of the key screens. We iterate on the design until you approve it, before writing a single line of code.

Step 03

Development

We build what was approved. Here the structure is locked: text and images can be adjusted, but the site architecture is not rebuilt.

Step 04

Go live

We prepare the launch and publish your site. This final stage is fully handled by my team and me, end to end.

FAQ

What clients ask

If your question isn't here, write to me and I'll answer it.

Do you build sites in WordPress, Webflow, Shopify and WooCommerce?
Yes, I work with all four and pick the one that fits each project, not the trendy one. WordPress with Elementor for content sites, corporate sites and landing pages; WooCommerce when the store needs full control and deep WordPress integration; Shopify when the priority is selling fast with less maintenance; and Webflow when the goal is a highly custom design with agile editing. We choose the platform based on your goals, your budget and who will maintain the site afterwards. I lead that technical decision and werun.dev builds it to the same standards on any of them.
Do you analyse my brand and current site before proposing anything?
Yes, we always start by understanding what you have today. I review your current site, your brand identity and how you work to spot the real pain points: performance, structure, SEO, security, maintainability and anything that slows you down or quietly costs you money. That honest diagnosis is what sets the priorities: I don't propose rebuilding everything by default, I propose what actually moves the needle in your case.
Do you handle maintenance and hosting after launch?
Yes. The site doesn't end the day it goes live: I support you with recommended hosting, updates, backups, performance monitoring and continuous improvements so it never drifts. You can leave it in our hands or keep your team running it with clear processes. Either way the goal is the same: a site that stays fast, secure and up to date over time.
What is a Fractional Head of Development?
A senior technical leader who joins your company part-time and owns technical strategy, team leadership and delivery: the same scope as a full-time CTO or VP of Engineering, but on a monthly retainer instead of salary and equity. For SaaS founders, agencies and scale-ups it is the fastest way to access senior technical judgment without the cost or commitment of a full-time hire.
How is a Fractional CTO different from a consultant?
A consultant writes a report and leaves. A Fractional CTO gets inside the team for months, decides alongside the founders, hires and mentors engineers, owns the technical roadmap and writes code when it is the fastest path. The relationship is operational, not advisory.
When does it make sense to bring in a Fractional Technical Director?
Three typical triggers: (1) you are about to scale the team and need a reliable hiring plan and architecture; (2) the team ships but technical debt slows every release; (3) the founders need someone who can translate technical risk into plain language for the board or investors. A 3-6 month engagement usually pays for itself in the first quarter.
What does a WordPress technical audit cover?
Four layers: code quality (plugins, theme architecture, custom integrations, dependencies), infrastructure (hosting, caching, CDN, backups, DR), performance (Core Web Vitals, server timing, database) and team or process (deploy, CI, on-call). You get a written report with prioritized findings and a 90-day remediation plan.
Which WordPress hosts and platforms do you work with?
I work directly with Pressable, WP Engine, Kinsta and Automattic-hosted environments, with case studies published with Pressable on hosting migrations and cost reduction. I am a partner-level contact at Pressable and have a direct relationship with Automattic and Elementor.
Do you build with Elementor and Elementor Pro?
Yes. Elementor selected me for its User Stories project in 2021 and I shipped more than 50 production sites with Elementor and Elementor Pro at the agencies I led (500 Designs, C42.Studio, Globant). I combine it with custom blocks or React when the project needs more interactivity.
What does an engagement look like and how long does it last?
Most run 3-6 months on a monthly retainer. Weeks 1-2 are the audit, weeks 3-4 the plan, and from week 5 I embed alongside the team: code, hiring, mentoring, vendors. The handoff includes documented decisions, a runbook and a team that is stronger than when I arrived.
Where are you based and which time zones do you cover?
I am based in Buenos Aires, Argentina (UTC-3) and work with teams across the Americas and Europe. I have led distributed teams in Argentina, Venezuela, the Philippines and the United States. Multi-timezone delivery is the default.
