Open to Software Engineering InternshipsCurrently building backend side-projects with C#/.NET and MongoDB, and exploring reverse engineering & systems security.
About
Code has been my favorite puzzle since I rebuilt my own development environment from scratch — terminal, editor, and all — just to understand how the pieces actually fit together. That curiosity is what pulled me toward backend development: I like systems where correctness and performance both matter, and where one misplaced index can make or break a product.
As a second-year Computer Science student, I spend time outside class building small backend projects with C#/.NET and MongoDB, picking apart binaries to understand how software works under the hood, and tuning my own tools until they're exactly right. One recent project — a real-time pipeline built on MongoDB Atlas Stream Processing — cut manual data-wrangling time on a class dataset by roughly 40%.
I'm working toward backend engineering and systems security roles, and I'm always glad to talk databases, dev tooling, or reverse engineering. Feel free to connect — I'd love to hear what you're building.
Experience
Real-Time Data Pipeline — MongoDB Atlas Stream Processing
College Project · Tel Aviv-Yafo Academic College · Mar 2026 – Present
- Designed and built a streaming pipeline using MongoDB Atlas Stream Processing to ingest and aggregate live data for a coursework dataset
- Reduced manual data-wrangling effort by roughly 40% by automating ingestion and transformation steps
- Presented results to 25+ classmates and the course instructor
Personal Developer Environment & Tooling Suite
Independent Project · 2024 – Present
- Engineered a cross-platform configuration system (editor, terminal multiplexer, shell, Git) to standardize and version-control a personal dev setup
- Automated environment provisioning across machines, cutting new-machine setup time from hours to minutes
- Maintained the project as a living reference for ongoing workflow improvements
Binary Analysis & CTF Practice
Self-Directed / Security Club · 2025 – Present
- Practiced reverse engineering and vulnerability analysis on sample binaries using disassembly and decompilation tools
- Solved beginner-to-intermediate CTF challenges focused on binary exploitation and reverse engineering
- Built foundational skills in low-level debugging and systems security
Peer Tutor, Introductory Programming
Volunteer · Tel Aviv-Yafo Academic College Coding Club · Sep 2025 – Present
- Tutored first-year students in C# and data structures fundamentals, improving exam pass rates among tutees
- Organized weekly study sessions for a group of 8–10 students
