Opus 4.7 Claude Code Hackathon: Meet the Winners — Medical Training, Electronics Repair, and CS Education

The Second Built with Opus 4.7 Hackathon

Anthropic's second Built with Opus 4.7 Claude Code hackathon drew over 20,000 applicants globally, from which 500 builders were selected to participate in a five-day build sprint. Approximately 250 projects were submitted, with a $100,000 prize pool distributed across winning entries. Each participant received $500 in Claude API credits to work with during the competition.

The winners, announced in June 2026, represent an unusually diverse group: a physician in Istanbul, an electronics repair technician in the French Alps, and a computer science teacher in Chile took the top three spots. None of the top winners have a traditional software engineering background, underscoring Anthropic's positioning of Claude Code as a tool accessible to domain experts who want to build software without deep coding expertise.

First Place: MedKit (Istanbul)

Bedirhan Keskin, a physician from Istanbul, built MedKit, a gamified clinical training simulator. Medical students interact with an AI patient, take clinical histories, order lab tests, make diagnoses, and receive scored feedback against published clinical guidelines. The system essentially allows junior doctors and medical students to practice the full diagnostic reasoning process on AI patients before encountering real ones, with structured scoring that reflects actual clinical standards.

Second Place: Wrench Board (French Alps)

Alexis Chapellier, an electronics repair technician from Reignier-Esery in the French Alps, built Wrench Board, an AI-powered diagnostic tool for board-level electronics repair. The tool guides independent repair technicians through step-by-step diagnoses from circuit schematics, making expert-level troubleshooting accessible to technicians who may lack the specialized knowledge to interpret complex component-level failures without guidance.

Third Place: Maieutic (Chile)

Paula Vasquez-Henriquez, a computer science teacher from Concepcion, Chile, built Maieutic, an educational coding IDE named after the Socratic teaching method. The platform requires students to explain their reasoning and intent before the code editor is unlocked, with Claude evaluating the quality of each explanation. Students cannot use autocomplete or proceed to writing code until they have articulated what they are building and why. The approach targets a widely recognized problem in CS education: students who can write syntactically correct code but lack conceptual understanding of what it does.

Special Prize Winners

Beyond the top three, several additional prizes were awarded:

• Most Creative Use of Opus 4.7: Virtual Puppet Theater, a browser-based interactive puppet performance environment built by Rene Hangstrup Moller from Denmark.
• Keep Thinking Prize: MaestrIA, built by Benjamin Torralbo on Chiloe Island, Chile, providing expert-level home repair diagnostics.
• Best Use of Claude Managed Agents: ARIA, an industrial factory maintenance AI system built by Idriss Benguezzou and Adam Hnaien from France, which won for its use of multi-agent orchestration in a production industrial context.
