Tutor online Giava in tutto il mondo

Full-Stack Swift & App Development Tutor I teach app and web development focused on Swift, iOS/macOS frameworks, backend Swift (SwiftNIO, Vapor, Hummingbird), and WebRTC/E2EE systems. Based in Yuen Long, I combine 15 years of one-to-one teaching with 12 years of public speaking and 8 years of professional software engineering. What sets me apart: - **Production experience:** built enterprise software for banks, healthcare, and SaaS; familiar with CI/CD, Docker, and secure deployments. - **End-to-end skills:** client (AppKit, UIKit, SwiftUI, Skip.tools) and server (SwiftNIO, Vapor, Hummingbird), plus networking (WebSockets, IRC, STOMP, HTTP) and E2EE (Double Ratchet, PQXDH). - **Teaching + presentation:** long history of course creation and public speaking—ideal for demo prep, interviews, and portfolio coaching. Teaching style: - **Project-based:** learn by building production-ready features or apps. - **Hands-on:** live coding, code review, and measurable milestones. - **Career-oriented:** interview prep, architecture guidance, and deployment walkthroughs. Core topics: - Swift (full-stack): SwiftUI, UIKit, AppKit, SwiftNIO - WebRTC, VoIP, secure messaging, E2EE - Server-side Swift: Vapor, Hummingbird, AsyncHTTPClient - Networking: TCP, WebSockets, STOMP, IRC, HTTP - CI/CD (Azure Pipelines), Docker, deployment - Web front end: NUXT/Vue.js, HTML/CSS/JS - App security and protocol design Selected highlights: - Built E2EE SDKs (DoubleRatchetKit, PQXDH integration) and WebRTC tooling. - Developed SaaS and cross-platform communication SDKs. - Created and taught multiple iOS app development courses; currently editing an AI-driven app course. If you want practical, career-focused lessons to build real products or prepare for technical roles, I’ll design a personalized curriculum with clear milestones.

I am an experienced programmer who has 8 years of industrial experience and 2 years of teaching experience.

I like to teach people programming. When I was a student, I enjoyed helping my friends and classmates with math problems and solving them together, which made me happy. So, when I became a software engineer, I didn't stop teaching people who are interested in programming. I am a Senior Java software engineer, and I would like to teach others how to become a developer and an expert in the field.

I graduated from Nanyang Technological University with First Class Honours in Computer Science and hold a Master’s in Technology Management. I previously studied at Raffles Institution, achieving 90 Rank Points for my A-Level examinations. Alongside tutoring, I work full-time as a Software Engineer, building and maintaining production-level systems in the technology industry. This enables me to teach not only academic theory, but also how software engineering is applied in real-world environments — including debugging practices, system thinking, and writing clean, maintainable code.

I have 4 years of experience in the software engineering field. I graduated with double majors in Computer Science and Financial Mathematics and Statistics.
