Alejandro Sanabria is a Forward Deployed Engineer at Wonderful.ai and a mobile platform leader with deep iOS and Android experience.
His core chapter is mobile: 8+ years building products and platforms at Platzi, growing from one of the first mobile engineers into leading mobile engineering across iOS and Android.
Earlier, he spent nearly five years co-founding and leading engineering for client-facing B2B products at Brand Spa. That full-stack foundation now supports the same product-engineering lens he brings to FDE work: customer problems, architecture, delivery systems, code quality, practical AI workflows, and fast mobile execution when the product needs it.
Forward Deployed Engineer at Wonderful.ai, working close to customers, product needs, AI systems, and implementation.
Grew from one of Platzi's first mobile engineers into leading iOS and Android platform work across native Swift, Kotlin, and React Native systems.
Builds AI-assisted iOS architecture workflows, App Store automation, simulator screenshot tooling, and repeatable delivery systems.
Built and published Cifro, a private-by-design iOS finance app using SwiftUI and Apple Foundation Models for on-device AI.
Co-founded a digital agency and led full-stack engineering for B2B client products, from architecture to production delivery.
Short engineering management chapter getting a first iOS version moving quickly under product and delivery constraints.
My longest and deepest chapter was at Platzi, where each phase taught me something different about how mobile software gets built at product scale.
Joined as the second mobile engineer. Small team, big product, everything to figure out. That's where I learned Swift and SwiftUI deeply — and where I learned that quality isn't the opposite of speed; it's what makes speed sustainable.
Then the platform outgrew its stack. I was part of the team that migrated from React Native to fully native apps — Swift on iOS, Kotlin on Android. Working across all three paradigms taught me what each approach actually costs and where each one breaks.
The migration wasn't about picking a side. It was about understanding the trade-offs deeply enough to make the right call for the product.
Leadership came next. Not away from engineering — deeper into it. Helped scale the mobile platform across both iOS and Android, and pushed to turn technical debt reduction from a wish list into a discipline.
A shorter Baubap chapter reinforced the same pattern from an engineering management seat: align product, platform, and delivery quickly enough to get a first iOS version moving in a compressed timeline.
Before mobile, I co-founded Brand Spa, a digital agency where I led engineering and built full-stack products for B2B clients. That chapter made product constraints concrete: clients needed quoting systems, CMS platforms, e-commerce flows, website builders, and internal tools that worked in production.
Now I'm a Forward Deployed Engineer at Wonderful.ai, bringing the same mobile/product builder mindset closer to customers, product context, AI systems, and implementation.
The two sides aren't separate. The best technical decisions come from understanding the team, the product, and the business context — and the best teams are built around a clear technical vision that compounds product outcomes.
Android scope: I've led it directly — shared architecture decisions, critical unblocking, and unified execution standards. iOS and Android move best as one team, not two silos.
I'm applying AI to the parts of engineering where context, review, and repetition usually slow teams down.
The work is practical: tools and workflows I use to plan, build, verify, package, and release real software.
The goal is not AI for its own sake. The goal is better engineering judgment, faster feedback, and working systems.
8+ year mobile chapter growing from one of Platzi's first mobile engineers into leading iOS and Android platform work. Helped move the platform from React Native to native Swift and Kotlin, scale shared standards, and build the team behind Apple-recognized Foundation Models and Liquid Glass work.
Reusable workflow patterns for iOS architecture, implementation planning, code review, validation, App Store operations, and screenshot generation. The focus is not prompt tricks — it's encoding practical engineering judgment into repeatable systems.
ios-architect-skillA published private-by-design iOS finance app built with SwiftUI and Apple Foundation Models. Cifro uses on-device AI for transaction parsing, budget bucket suggestions, daily insights, and a review ritual — no accounts, no cloud, no data sharing.
View on App StoreCommand-line tooling that supports the mobile delivery workflow: App Store Connect metadata and build upload automation, plus deterministic iOS simulator screenshot capture for App Store assets, regression checks, and CI pipelines.
appstore-tools screenshots-iosCo-founded and led the engineering side of a digital agency for nearly five years, serving as the principal engineer across client projects. Built custom web solutions from architecture to production using PHP, Laravel, Ruby on Rails, WordPress, React, and Node.js.
A short engineering management chapter focused on getting Baubap's first iOS version moving quickly: aligning product, mobile architecture, delivery constraints, and team execution around a compressed timeline.
Current Forward Deployed Engineer role at the intersection of customer workflows, product constraints, AI systems, and implementation. This is the current role and direction.
