I'm Andrei — Full-stack engineer who ships production-ready platforms from AWS microservices to native iOS apps.
Full Stack Developer
Architected a comprehensive e-commerce orchestration platform using NestJS microservices with GraphQL Federation and event-driven AWS SQS messaging. Built a unified React Router 7 admin portal with SSR and deployed the entire system to AWS ECS Fargate via CI/CD pipelines. Led TypeScript-first practices and established comprehensive testing and code quality standards across the monorepo.
iOS Developer
Built and maintained a white-label enterprise mobile platform serving multiple client brands from a single codebase using Swift and Kotlin Multiplatform. Implemented a real-time WebSocket chat system handling thousands of concurrent users with offline-first architecture. Reduced cross-platform development effort by 40% through KMM shared business logic and cut release time from days to hours with Fastlane automation.
Cloud Developer
Worked on CardioHPC, a cardiac monitoring system predicting heart attack likelihood within 5 minutes, redesigning its architecture into a FaaS implementation. This research inspired a bachelor thesis building a multi-cloud scheduler that distributes computationally intensive workflows across AWS and GCP. The scheduler optimized workflows by simultaneously minimizing makespan and execution costs.
iOS Developer
Developed and maintained production iOS applications using Swift, SwiftUI, and UIKit, integrating cloud services from AWS and GCP. Architected features following MVC and MVVM patterns, created reusable Swift Package components for RESTful API integration, and implemented comprehensive test coverage with XCTest and XCUITest.
