Teddy Mbayaki

Software Engineer targeting Frontend AI Engineering roles, with 2 years of backend experience at Xiracom designing, developing, and maintaining scalable backend systems and APIs. Currently building and shipping production frontend applications with real LLM integrations through the FlyRank AI Fluency internship — using React, Next.js (App Router), and TypeScript to ship features, debug live deployment issues, run accessibility and performance audits, and write tests. Proficient in building cloud-native applications, managing SQL and NoSQL databases, and deploying applications on AWS.

Strong problem-solving and troubleshooting abilities, with a proven track record of collaborating with cross-functional teams to deliver reliable, high-quality software solutions.

Frontend AI Engineering & AI Fluency Intern at FlyRank AI Internship (2026-06 – Present)

• Migrated a weather dashboard capstone project from React/Vite to React, Next.js (App Router), and TypeScript, scaffolding routed pages and deploying to Vercel with automatic preview builds on every push.
• Built a streaming, multi-turn AI chat feature (Vercel AI SDK + Google Gemini) grounded in live weather data, including a thinking-state indicator, a working stop/resume flow, and mobile-responsive layout built with React and Tailwind CSS.
• Diagnosed and resolved a production deployment failure where the build succeeded and every route was listed, but the live site 404'd — traced to a misconfigured Vercel Framework Preset setting, not application code.
• Improved Lighthouse mobile performance score from 49 to 85 (a 73% increase) by lazy-loading a non-critical AI SDK bundle, and resolved all WCAG 2.1 AA accessibility violations from 2 down to zero, verified with axe DevTools.
• Wrote 4 passing unit tests (Vitest, React Testing Library) covering 2 core UI components as part of a test-driven verification pass before deployment.
• Practiced and documented structured prompt-engineering techniques — role assignment, context framing, few-shot examples, output structuring, step decomposition — across real debugging and content-generation tasks, with cross-model comparison (Claude vs. ChatGPT).
