I'm a software engineer. I built and shipped Resecta, an open-source iPhone app for redacting PDFs, on my own. Before that, I spent three summers at Fidelity Investments (Java/Spring Boot, Node.js, Angular) and earned a BS in Computer Science from UMass Amherst in 2023.

Looking for a full-time software engineering role. Available now; open to remote work or relocation.

A black box drawn over a PDF can leave the text underneath in the file. Resecta turns every page into a flat image, overwrites the regions you marked in the pixels, and rebuilds the file from those images, so redacted text is removed rather than covered.

On-device detection suggests names, account numbers, and other personal details; nothing is redacted until you confirm. By default, Resecta then reopens the finished file, re-runs your searches and a detection sweep on it, and flags what it still finds. It is free, with no account, no analytics, and no network requests of its own.

I started Resecta in April 2026, open-sourced it in July, and shipped it to the App Store in August. The app and its redaction engine are Swift (SwiftUI, PDFKit, Vision). A separate Python pipeline builds and signs the detection data, and the app verifies that signature at load.

• Code: resecta (app and redaction engine) · resecta-datapipeline · resecta-sample-doc (synthetic test PDFs)
• Design: ENGINEERING.md (each claim, its check, and that check's limits) · THREAT-MODEL.md (what it defends against, and what it doesn't)
