Sebastien Lato

Mobile & Web Developer

Hey! I’m Sebastien 👋, a mobile and web developer who enjoys building sleek, interactive apps and websites that actually work well.

I specialize in Swift, SwiftUI, JavaScript, React, and Next.js—and I love making things feel smooth, fast, and just a little bit delightful.

I’m big on clean UI, good UX, and writing code that doesn’t need a search party to debug.

Outside of dev work, you'll find me tweaking layouts at 2AM, sipping overpriced coffee, or impulse-buying gadgets I absolutely convinced myself I needed 😅

Projects

SecureVault

SecureVault is a SwiftUI password manager purpose-built for iOS. It keeps every credential encrypted on-device, unlocks with biometrics, and presents a thoughtfully designed UI for organising, auditing, and sharing passwords. It's built with SwiftUI, Swift, and Combine, ensuring fast performance, responsive design, and a clean, premium look.

PetSitterQR

PetSitterQR is a SwiftUI app for creating and sharing pet care cards via QR codes. Owners can manage pets locally with optional photos and generate text-only QR codes. Sitters can scan these codes to instantly view or import care details onto their device. The app includes GlassCard UI, detailed care sections, and secure on-device photo storage. Built with SwiftData, it offers a clean structure across features, services, models, and design system.

SleepSoundsApp

Sleep Sounds App lets you stack calming ambient loops like rain, ocean waves, and fireplace crackles. Each sound has one-tap play/pause, animated volume controls, and its own accent color + SF Symbol. A built-in sleep timer offers presets, wheel pickers, and a live countdown that fades audio out automatically. Behind the scenes, lightweight SwiftUI services manage looping audio, volumes, haptics, and session interruptions. The project is built entirely in SwiftUI, organized into Features/Services folders for a clean, scalable architecture.
