B2B platform for turning customer interviews into searchable evidence and approved content.

TypeScript, React, Python, PostgreSQL, Supabase, GCP, Langfuse

• Delivered a client-testable, multi-tenant beta in three weeks as the sole engineer; now own platform development and operations. Use AI-assisted development with architecture review, adversarial reviews, testing, and CI quality gates.
• Turned the founder's requirements and UI prototypes into production React/TypeScript workflows for searchable quote libraries, customer approvals, and versioned content publishing, integrating application state, APIs, and database access.
• Replaced manual transcription, ChatGPT, and spreadsheet handoffs with a Python pipeline on GCP Cloud Run and Cloud Tasks. Integrated automated quote extraction and scoring with in-app review and import, plus Langfuse tracing and prompt management; moved processing off Edge Functions to address execution-time limits.
• Implemented PostgreSQL row-level security for tenant isolation and built a role-matrix regression harness that checks database access permissions in CI when migrations change.
• Built five production Model Context Protocol (MCP) servers for internal operations and customer-facing integrations, connecting AI assistants to data and workflows with OAuth 2.1 authentication and access controls.

Construction software for contractors, with project management, invoicing, and payments across web and mobile.

TypeScript, Next.js, React Native / Expo, Fastify, PostgreSQL, Stripe, RevenueCat

• Designed and shipped subscriptions across web, iOS, and Android, unifying Stripe and RevenueCat purchases in a shared PostgreSQL entitlement store. Owned requirements clarification, the implementation proposal, and development, with design review from a technical consultant.
• Fixed a purchase-flow race that returned paying users to the paywall by adding synchronous purchase verification alongside asynchronous webhooks; implemented scheduled enforcement of trials and grace periods.
• Added five-role authorization, financial-field filtering, and invoice-sharing controls across API, web, and mobile. Preserved existing tenant behavior through per-organization rollout flags and regression tests.
• Built invoicing in React Native / Expo from creation through sending and voiding, including API routes, PDF generation, dashboard metrics, and Stripe Connect onboarding for payment collection.
• Authored approximately 294 unit and route test cases, including adversarial data-leak tests. Built subscription-aware Playwright fixtures and migrated 22 end-to-end specs to accommodate the new paywall.

JavaScript, Python, SvelteKit, Supabase, PostgreSQL

• Co-built a nightlife review platform, owning backend and data work while a technical cofounder led frontend development.
• Built custom JavaScript geolocation and venue-import logic and a Python geocoding pipeline for the initial platform; contributed to its SvelteKit and Supabase rebuild.
