Gabriel Petertonjes

I’m a Software Engineer Intern and computer science student pursuing a 4+1 pathway into an MS in Financial Engineering, where I blend engineering rigor with finance problem-solving. I bring a practical, build-first mindset—turning requirements into secure, maintainable solutions.

At Certifydoc in Barcelona, I architected and deployed an Ubuntu-based LAMP stack development environment with secure remote access (SSH/RDP), reducing team setup time by 30%. I also built a custom WordPress child theme with optimized file structure and API integration infrastructure to support scalable web development.

I’ve managed real operational and financial responsibility through leadership roles—overseeing accounting and budgeting for a $50,000 fraternity maintenance fund and coordinating day-to-day house operations for 32 residents. As Assistant Waterfront Director, I managed a $75,000 labor budget, processed biweekly payroll, and developed training programs while implementing scheduling to minimize overtime.

On the investment side, I contribute to student-managed portfolios by building financial models and performing valuation analysis (DCF, comps, precedent transactions) and presenting recommendations through pitch decks. I’m also strengthening quantitative skills through algorithmic trading and mathematical modeling via Lehigh Mountain Quants, including trading simulations focused on risk and execution.
