Working Experience
AI Engineer Intern — ShogunOS
- Platform Engineering: Co-built ShogunOS, a multi-tenant AI operations platform running 10 isolated departmental AI agents per company, working across the FastAPI backend, React portal, and vector-search knowledge layer from architecture to live customer deployment.
- Agent & Integration Architecture: Designed provider abstractions spanning 10 business domains so each vendor backend (accounting, HR, CRM, and more) plugs in behind one standard tool contract, and built the departmental dashboards that surface live business data in place of mock content.
- Security & Multi-Tenancy: Implemented role-based access control with department-scoped permissions and tenant isolation, then closed the platform's bot, onboarding, chat, and file-attachment attack surface across six rounds of adversarial review.
- Delivery Infrastructure: Automated provisioning, install verification, and job backup/restore to make full multi-agent deployment a reproducible ~30-minute run, and set up test-gated CI running ~500 tests on every pull request.
Software Engineer Intern
- Architecture & Scalability: Engineered and optimized core backend components for enterprise-grade lending software, ensuring high availability and secure processing of financial data.
- Code Quality & Agile: Collaborated cross-functionally in fast-paced sprints to refactor legacy codebases, reducing technical debt and improving overall system maintainability.
- Defect Recovery: Actively participated in system debugging and performance tuning, resolving software defects and ensuring reliable data pipelines.
Technical Skills
Crafting High-Performance User Interfaces
I specialize in translating complex requirements into responsive web and mobile applications using TypeScript and Next.js. Through competitive hackathons, I have mastered the art of building data-rich dashboards and cross-platform mobile apps with Flutter, focusing on Core Web Vitals, strict type safety and seamless UI/UX design in Figma. My approach emphasizes reusable component architecture and "Local-First" data strategies to ensure performance even in low-connectivity environments.
