Security & AI Systems Developer | Building tools that protect users from digital friction and human error.
π‘οΈ VibeCheck β Sentiment Shield
- The Mission: Real-time emotional guardrails for social media (Twitter, Reddit, LinkedIn).
- The Impact: A privacy-first Chrome extension powered by a local FastAPI server and HuggingFace Transformers. Classifies 28 emotions in <800ms to filter toxic content entirely on-device.
- Tech: TypeScript, Python, FastAPI, RoBERTa (NLP), Vite
π PasteShield β Credential Guard
- The Mission: Preventing accidental PII and API Key leakage in the browser.
- The Impact: A security engine that intercepts native paste events to detect sensitive patterns (AWS, GitHub, Credit Cards) before they are submitted. Features a custom UI interceptor with power-user keyboard shortcuts.
- Tech: JavaScript (Chrome MV3), Regex-Engine, Local-First Whitelisting
- The Mission: Solving the "procrastination" barrier in personal finance management.
- The Impact: An iterative project that evolved from a Terminal MVP to a full GUI application. Built to solve real-world overspending habits through data visualization and comparison logic.
- Tech: Python, Tkinter (GUI), Matplotlib (Data Viz)
- Mathematics: Linear Algebra & Calculus for ML optimization.
- Local-First ML: Running NLP and classification models on-device for 100% data privacy.
- AI/ML: Predictive modeling, Feature Engineering, and Model Interpretability (XAI).
- Architecture: Scalable SaaS infrastructure and real-time data ingestion.
- Browser Forensics: Intercepting DOM events and system-level inputs to build safety guardrails.
- Iterative Engineering: Moving products from terminal-based prototypes to polished, user-facing interfaces.
- Privacy Architecture: Designing systems where no data ever leaves the user's machine.
