Alex Wang
I'm a fourth-year Computer Science student at UC Berkeley graduating in May 2027.
My interests include cloud, backend development, and related fields in software engineering. I'm excited about tackling ambiguous problems across the software stack.
Currently, I'm working on distributed systems research at the Sky Computing Lab.

Projects
Our City Forest
Mobile application streamlining inventory management for Silicon Valley’s largest forestry nonprofit!
Built serverless microservice processing bulk operations of 1,000+ QR-coded tags, eliminating manual printing workflows and reducing operational overhead for AmeriCorps members and administrators. Architected server-side QR generation system, enabling real-time tracking of diverse tree populations for nurseries and neighborhoods.
React Native, TypeScript, Supabase, Expo, Retool
Operating Systems Kernel Extensions
Engineered a transaction-safe Unix-style file system with multi-level inodes and rollback recovery. Implemented in-memory caching with fine-grained locking for concurrent disk I/O, and built a full POSIX-like threading subsystem with kernel-level synchronization primitives enabling true parallel execution.
Secure File Sharing System
Built a resilient end-to-end encrypted file sharing system enabling secure storage, access control, and revocation across untrusted infrastructure.
Designed user authentication, per-file encryption, and key-management logic ensuring confidentiality and integrity even under malicious servers. Implemented fine-grained sharing and revocation semantics allowing hierarchical sharing while guaranteeing that revoked users cannot regain access or infer file updates.
Deadbolt demo
Chrome extension that checks whether a housing post's photos are consistent with the city the poster claims, the question reverse image search can't answer. Built at HackMIT 2026.
Post selection uses no site-specific selectors, so the same build runs on Facebook, Craigslist and Zillow. Combines one structured vision call with locally-computed EXIF and perceptual hashing, then scores those signals with weights set in code rather than asking the model for a verdict. Flags a planted scam listing at 100/100 and clears an honest one at 12/100.
3D COVID-19 Lesion Segmentation
Developed a robust 3D nnU-Net-based segmentation pipeline to improve the accuracy of CT classification processes distinguishing COVID-19 from other viral pneumonia.
Leveraged segmented lung masks and lobe localizations as post-processing steps to enhance performance. The pipeline demonstrated improvements over baseline models in Dice scores and other metrics, showcasing robustness and transferability across diverse COVID-19 CT datasets.
Immersive Mixed Reality 
Developed HoloLens-ready Mixed Reality system for dynamic disaster simulation on LiDAR-scanned campus environment. Scripted physics-based object manipulation and interactive particle elements. Conducted pilot studies to effect effectiveness against current methods, and published results.
