Deliver full-stack, mobile, real-time, AI, and SaaS engineering across startup engagements, owning work from ambiguous requirements and architecture through implementation, testing, release, and production stabilization.

• Build systems with TypeScript, React, Next.js, Node.js, React Native, Go, Rust, PostgreSQL, Supabase, Redis, MongoDB, AWS, Stripe, and Terraform.
• Design multi-tenant SaaS foundations with RBAC, billing, entitlements, webhooks, RLS, feature gates, and CI/CD.
• Build AI infrastructure for retrieval, persistent memory, tool-state orchestration, resumable execution, and LLM workflows.
• Diagnose race conditions, sync failures, access-control issues, regressions, and reliability problems in mature and AI-assisted codebases.

Selected engagements:

Handlet — Built multi-tenant AI SaaS with Next.js, Supabase, PostgreSQL and Stripe; implemented billing, webhooks, RLS, migrations, Unipile integrations, secure attachments, access-control audits, and tests.

Jukebox — Shipped a React Native/Expo app through EAS Build, TestFlight, device QA, and App Store release.

Xintra / Scholarly — Built reusable SaaS foundations, real-time desktop sharing, a no-code app builder, and Gmail/Outlook workflow automation.

• 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.

Worked on a production edtech platform serving approximately 50K users.

• Improved subscription-aware class registration, recurring-class, and eligibility workflows.
• Strengthened Stripe-backed plan logic and downgrade cleanup to prevent invalid future registrations.
• Designed SaaS capabilities including RBAC, invitations, billing, entitlements, and feature gating.
• Architected persistent AI workflow infrastructure for memory, retrieval, and tool-state orchestration.
• Worked within a mature TypeScript codebase with strong emphasis on regression prevention, backward compatibility, and production safety.
