Deliver full-stack, mobile, real-time, and AI SaaS engineering across multiple startup and product engagements.

• Take ownership of ambiguous requirements, existing production systems, architecture decisions, implementation, testing, and release readiness.
• Build and stabilize TypeScript applications using React, Next.js, Node.js, Supabase, PostgreSQL, Redis, Stripe, and cloud services.
• Review mature and AI-generated codebases, identifying architectural risks, missing test coverage, entitlement defects, synchronization failures, and production regressions.
• Implement multi-tenant SaaS foundations involving RBAC, invitations, billing, entitlements, feature gates, webhooks, secure file access, and realtime workflows.
• Develop AI-product infrastructure for memory, retrieval, tool state, resumable execution, and user-facing assistant experiences.
• Apply Playwright-style end-to-end validation and TypeScript testing to protect critical customer and billing flows.

Xintra & Scholarly:
- Created a SaaS starter template reused across multiple products: a live test-taking platform, an AI-based 3D modeling asset marketplace, and a 1:1 mentoring app.
- Built a real-time desktop sharing tool (15+ FPS, low latency) enabling remote simulations and training.
- Developed a no-code app builder for rapid prototyping of internal apps.
- Built a Gmail/Outlook add-on to automate transport bid margin calculations from emails

• Build and maintain a multi-tenant AI-native SaaS platform using Next.js, Supabase, Stripe, and realtime communication workflows.
• Implement entitlement enforcement, billing logic, webhooks, Row-Level Security, database migrations, and CI/CD processes.
• Develop realtime inbox integrations through Unipile and secure attachment-access workflows.
• Review access-control behavior across application, database, and billing layers to prevent unauthorized feature use.
• Strengthen critical flows through TypeScript testing and end-to-end validation.
• Support production debugging and incremental improvement without introducing unnecessary architectural complexity.

• Improved production class-registration, recurring-class, and subscription-access workflows serving approximately 50,000 users.
• Strengthened downgrade cleanup and plan-based eligibility logic so invalid future registrations did not persist after subscription changes.
• Designed workspace-oriented SaaS capabilities involving RBAC, invitations, Stripe billing, entitlements, and feature-gated workflows.
• Implemented regression-safe service logic for scheduling, student registration, and subscription-dependent behavior.
• Architected persistent AI workflow infrastructure for memory, retrieval, and tool-state orchestration across multi-step sessions.
• Collaborated within a mature TypeScript codebase where correctness, backward compatibility, and production safety were critical.
