I'm a Computer Science graduate from The Hebrew University of Jerusalem who enjoys building real systems and understanding how things work under the hood. I'm interested in backend, systems-level, and security-adjacent development — projects that touch networking, infrastructure, and low-level details.
- Building personal projects with production-like architecture
- Background in data structures, algorithms, operating systems, and networking
Languages
- Python, Kotlin, TypeScript/JavaScript, C#, C++, C, Java
Backend & Web
- Node.js, Express, React
- REST APIs, JWT authentication, client-server architecture
Databases
- PostgreSQL, SQLite, Drizzle ORM
Mobile
- Android (Kotlin, RecyclerView, WebView)
Cloud & DevOps
- AWS (EC2, S3), Docker
- Git, GitHub Actions CI/CD
Systems & Networking
- Linux, TUN/TAP, UDP sockets, NAT, IP forwarding
- AES-256-GCM encryption
https://github.com/yonisirote/minivpn
Functional Linux VPN built from scratch. Creates TUN interfaces on client and server, encrypts all traffic with AES-256-GCM, and tunnels it over UDP. Server configures IP forwarding and NAT/masquerading to route VPN clients to the public internet. Deployed on AWS EC2 with packet-level logging for ICMP, TCP, and UDP traffic.
Tech: Python, TUN/TAP, UDP sockets, NAT, AES-256-GCM, AWS EC2
https://github.com/yonisirote/hostmate
Full-stack meal planning app — hosts manage dishes and guests, collect preferences via ranking links, and get personalized menu recommendations. JWT auth with access/refresh tokens, protected API routes, SQLite database with Drizzle ORM. Deployed on Railway with GitHub Actions CI.
Tech: TypeScript, Express, React, SQLite, Drizzle ORM, JWT, Railway
https://github.com/yonisirote/readmyfeed
Native Android app that aggregates feeds from X/Twitter and Telegram and reads them aloud. Handles X authentication through a WebView login flow with cookie capture and cursor-based pagination. Integrated Telegram via a local TDLib build with JNI bindings. RecyclerView feed UI with per-provider row layouts and text-to-speech playback.
Tech: Kotlin, Android, TDLib, WebView, RecyclerView, Text-to-Speech
Fixed and merged a bug where slash commands were lost when reopening threads — navigated a large Rust codebase and went through maintainer code review.
