ABOUT

lines

I’m a Software Engineer at Google, working on Ads/AdMob EngProd, where I build automation and test infrastructure across Android and iOS. I hold a BA from Brown University and an MSc in Computer Science from the University of St Andrews, graduating with First Class Honours with Distinction. Throughout my studies and career, I’ve sharpened my skills in software development, release engineering, data science, and AI, with hands-on experience across Python, Java, JavaScript, TypeScript, SQL, Go, and a range of full-stack and machine learning technologies.

I’m always eager to learn and innovate, constantly seeking opportunities to expand my skill set and make a meaningful impact in the tech industry and beyond. My Master’s dissertation applied machine learning and computer vision to pathology research in mast cell diseases, and I continue to explore how AI and automation can solve real-world problems. I’m excited to keep applying my expertise and contribute to groundbreaking technologies as my career grows.

What I Do

lines
Full Stack Developer

Full Stack Development

  • Proficient in responsive, interactive front ends using HTML5, CSS3, JavaScript, TypeScript, and frameworks like React, Angular, and Vue.js.
  • Strong back-end experience in Java, Python, and Node.js/Express, with RESTful API design and databases including MySQL, MongoDB, and Firebase.
  • Built and launched a full-stack site end-to-end as a paid contractor, from wireframes to deployment, improving discoverability 21% through SEO best practices.
  • Skilled in building responsive, accessible UIs with Bootstrap and Figma.
  • Utilized Git/GitHub for version control and JIRA for project management.
Machine Learning & AI

ML, AI, & Data Science

  • Expertise in Python with ML libraries including TensorFlow, PyTorch, Keras, scikit-learn, and XGBoost for classification and deep learning.
  • Built an end-to-end computational biology pipeline for my Master's dissertation, applying clustering, hypothesis testing, and classifier tuning to microbiome and biopsy data, achieving 91%+ accuracy on a clinical dataset.
  • Designed generative AI (GAN-based) and traditional data augmentation strategies to work around a severely data-limited clinical dataset.
  • Applied computer vision (YOLOv8) and biomedical image analysis to detect and quantify cells in histology/biopsy images, improving detection accuracy by 25%.
  • Built an agentic, Gemini-powered pipeline at Google that autonomously analyzed system logs to surface failure points across 5 product lines.
Mobile, Test Automation, & Release Engineering

Mobile Dev, Test Automation, & Release Engineering

  • Design and build large-scale test automation frameworks and CI/CD pipelines for mobile platforms, reducing manual QA effort and release risk.
  • Drive release-engineering initiatives end-to-end, from technical design docs through implementation and rollout.
  • Build performance-monitoring and observability tooling (latency, memory, and stability metrics) to catch regressions before they reach users.
  • Automate bug triage and test-result analysis at scale, using scripting to cut manual backlog work and speed up debugging.
  • Comfortable owning cross-platform mobile infrastructure end-to-end, from architecture and physical-device testing to on-call support.
