Hi, I'm

Abderra
El Haitout

CTO & Product Leader · Barcelona

Most companies split who decides what to build from who decides how to build it. For 15 years I've owned both — as founding partner, CTO, and product owner at Mubawab.

What I bring

01

Product thinking

I decide what to build and why — grounded in user behaviour, sector analysis, and cross-functional input from Sales, Marketing, and Finance. Conversion is always the final judge.

02

Technical depth

I know how to build it right. From architecture decisions to engineering standards, I translate business constraints into technical direction — without losing sight of either.

03

Business acumen

I connect technology and product to revenue. I've managed paid acquisition, designed monetisation products, and made trade-offs with P&L implications — as a founding partner, not just an executor.

04

Team building

I built an engineering team from zero, conducted every hire personally, and maintained near-zero attrition since 2017. I know how to grow people, not just headcount.

Who I am

I'm a technology and product leader who has spent 15 years at the intersection of engineering, product, and business. I joined Mubawab as a backend engineer, grew into CTO, became a founding partner — and along the way took full ownership of the product as well. Not because it was in my job description, but because the two roles are inseparable when you're building something that actually works.

After four years, I was offered a stake in the company as a founding partner. That shift changed everything: from executing someone else's vision to having real skin in the game. It's the reason behind my 15-year tenure — and behind the long-term, business-first lens I apply to every technical decision.

What defines my approach is a simple conviction: technology serves the business, not the other way around. I'm equally comfortable deep in a backend codebase, defining a product roadmap with stakeholders, analysing CPL across acquisition channels, or navigating the ambiguity that comes with fast-moving environments. I don't do tech for the sake of tech.

Outside work I apply the same discipline to running — 5 marathons completed and training for the 6th — and to basketball, a sport I've played for 20+ years and that shaped how I think about teamwork.

Experience

Chief Technology Officer

Mubawab · Sant Cugat del Vallès

Sep 2013 — Present

Grew from Backend Engineer to CTO — and eventually founding partner — at Mubawab, the leading real-estate portal in Morocco and Tunisia. Joined when the company had 6 people and 10K monthly visits; scaled it to 200 employees and over 1M stable monthly visits before a focused restructuring brought it to its current 70-person setup. Built and led the entire technical organisation from zero across Barcelona, Tunis, and Casablanca.

Team Building & Culture

  • Built the engineering team from scratch: sourced, filtered, and personally conducted every single hiring process — from junior engineers to senior architects — growing the team to 14 across three cities
  • Core team has been stable since 2017, with near-zero attrition — unusually strong retention in an industry where engineer churn is endemic
  • Implemented Agile (SCRUM) and continuous integration workflows; defined engineering standards and technical culture from the ground up

Product Strategy & Design

  • Run continuous cross-functional sessions with Sales, Marketing, Finance, and HR to surface needs and translate them into product solutions — then design and scope those solutions with the engineering team before committing to build
  • Product decisions are grounded in three inputs: worldwide sector analysis to identify emerging patterns, Hotjar for session recordings and heatmaps, and A/B tests where conversion is always the deciding metric
  • Pivoted the product from a generalist classifieds platform (cars, jobs, real estate) to a focused real estate vertical — a strategic call that defined the company's long-term positioning
Product launch · 40% adoption among paying clients
Listing Stories

Sales needed a new premium format to increase ARPA on existing accounts — something differentiated, not just another visibility boost. I designed an Instagram-style short video attached to a listing, displayed at the top of search results. It gave agencies a genuinely new tool to pitch, and 40% of paying clients adopted it.

Product launch · 2% paid conversion from a previously free segment
Smart Buyer Notification

Finance flagged that 30% of our content came from private sellers who paid nothing. I designed a monetisation product around our buyer intent data: dynamic pricing based on how many active buyers match a seller's property profile, with an instant notification sent to those buyers on publish. It turned a free segment into a new revenue stream.

Product & Business Impact

  • Lead conversion rate grew from 1% to 8.6% across 1M+ monthly visits — driven by sustained A/B testing, mobile-first design, and continuous user behaviour analysis
  • Time on site increased 70%; photos viewed per session up 700% — reflecting a deliberate shift toward content quality and engagement
  • Reduced average page load time from 5s+ to 2.4s — a critical metric for MENA markets where mobile connectivity is limited and load time directly impacts conversion
  • Directly involved in paid traffic acquisition: managed CPL and CPC across multiple platforms, balancing budget between providers to find the best-performing channel mix

Infrastructure & Architecture

  • Designed the cloud architecture around three principles: high availability (minimum two instances per service behind a load balancer), auto-scaling (new instances triggered automatically when CPU crosses a defined threshold), and self-healing (instances failing health checks are removed from the load balancer without manual intervention). Applied consistently across all services — application servers, database, Solr indexing, and SMTP — migrating from a single shared server to 15+ AWS instances as traffic grew 100×
  • Defined and executed the technical roadmap alongside Product, Sales, and Marketing; scaled infrastructure and product across 25 markets at peak international expansion
  • Built an internal commercial tool in React used by the sales team to manage priority call queues and record all calls for quality control and coaching
Recent AI initiatives

Infrastructure & DevOps

Scaled platform infrastructure from a single server to a 15+ instance AWS architecture. Page load time brought from 5s+ to 2.4s — prioritised for MENA markets where connectivity constraints make performance a direct business lever.

Hobbies

🏃

Running

5 marathons completed and training for the 6th. Running is where I reset — there's something about covering 42 km on foot that puts everything else in perspective.

🏀

Basketball

Playing for 20+ years. Coached from 2008 to 2021, now just enjoy the game. The team-first mindset it builds sticks with you long after you leave the court.

⛩️

Manga & Anime

Since age 12. One Piece, Naruto, Bleach, FMA, Fairy Tail — the classics shape you. Currently always mid-arc in something new.
