I build end-to-end digital products: mobile apps, backends, distributed systems and cloud architectures, always focused on performance, UX, scalability and real-world impact. oai_citation:0‡CV-Eduardo-Lourenco-Linkdedin-en.pdf

I’m a Full Stack Software Engineer with 10+ years in tech, specializing in:

• Mobile-first experiences with React Native and Swift/SwiftUI
• Distributed systems & backend with TypeScript, Bun and Node.js
• Cloud & DevOps across AWS, Azure and Google Cloud
• Clean architecture, CI/CD and observability
• Applied AI & Image Recognition embedded in mobile products

I like to transform ideas into robust, elegant and maintainable systems that survive scale, time and changing requirements.

• React Native (complex apps, offline-first, animations, native bridges)
• Swift & SwiftUI for high-performance native experiences
• Native iOS/Android integrations (Objective-C, Kotlin, Java)
• Data sync, caching strategies and network-resilient UX

• Bun & Node.js with TypeScript
• Ruby on Rails (APIs, MVC, ActiveRecord, Turbo/Hotwire)
• REST & GraphQL APIs
• PostgreSQL, MySQL, MongoDB, DynamoDB, Redis
• Event-driven patterns, queues and background jobs
• CI/CD pipelines, automated testing and delivery

• ONNX Runtime, TensorFlow, PyTorch experiments
• Image pipelines on mobile (camera → preprocessing → inference → UI)
• Performance tuning on device (memory, CPU, frame time)
• Integrating AI into real products, not just demos

I care about clean architecture, long-term maintainability and real-world constraints: network failures, offline usage, performance on low-end devices, and teams that need to move fast without breaking everything.

Good engineering, for me, is about clarity + consistency + sustainable speed.

If you’re looking for someone who can design, build and ship from backend to mobile, connect AI into real products and keep the system healthy in production, that’s where I operate best.
