Full-stack product engineer for products that need to ship.

Shipped product slices across Node/Express/Prisma services, Next.js/React web workflows, and Expo/React Native mobile features, contributing to three production codebases.

• Delivered full-stack product slices across Node/Express/Prisma services, Next.js/React web workflows, and Expo/React Native mobile features for security, receipts, reporting, analytics, admin tooling, and mobile parity.
• Built an API-key security lifecycle spanning Prisma schema/migrations, Express controllers/routes, OpenAPI, redaction/error utilities, tests, and web settings UX.
• Delivered unified incoming-receipt routing across backend, web, and native app layers with shared preferences, explicit-folder routing, transactional folder-resolution locking, rollback behavior, localization, and tests.
• Improved receipt and admin workflows including inline receipt editing, bulk category updates, duplicate-scan semantics, last-upload sorting, debounced folder search, user-list pagination, MRR reporting, and direct seat editing.
• Hardened WhatsApp receipt actions with atomic state commits, stale/duplicate-action rejection, localized feedback, and regression coverage across Meta and Evolution webhook paths.
• Improved upload reliability by moving 25–28 second OCR classification off the synchronous request path, replacing a global 30-second cutoff with a 120-second default, and validating a 36.01-second multipart upload.
• Expanded report history, OCR usage by channel, currency-aware MRR, user pagination, seat editing, and mobile exports with downloads, reruns, and CSV/XLSX/PDF support.
• Supported reproducible iOS IPA builds, Sign in with Apple, privacy configuration, Android/iOS App Links across two domains, and App Store asset and image-orientation fixes.
• Contributed 106 merged PRs across web (45), backend (29), and mobile (32), covering product workflows, reliability, testing, and release tooling.

Built and contributed full-stack features across the Next.js App Router, PostgreSQL/Drizzle data model, Auth.js/NextAuth authentication, RBAC, secure attachments, and realtime board updates.

• Built a department-first collaborative work-tracking platform spanning workspaces, workflow columns, tickets, cross-department sharing, comments, labels, activity history, invitations, attachments, and administrative oversight.
• Connected frontend, API, and database layers through reusable React workflows, shared TypeScript/Zod contracts, 32 route handlers, PostgreSQL, Drizzle ORM, and 21 database migrations.
• Implemented Auth.js credential sessions, session versioning, route protection, role- and workspace-scoped permissions, password and invite flows, database-backed rate limiting, and administrative safeguards.
• Integrated S3-compatible attachment and avatar storage with validation, staged persistence, size controls, protected preview/download behavior, missing-object handling, and recovery states.
• Authored 83 automated test files covering API routes, database behavior, authentication, responsive UI, accessibility, keyboard interaction, and end-to-end workflows.

Designed and built a production website end-to-end on Next.js 16, React 19, strict-mode TypeScript, WordPress CMS, and a tested dual-source content pipeline.

• Designed and built a production website end-to-end: ~34K LOC across 23 routes, 74 React components, and 6 API route handlers in strict-mode TypeScript on Next.js 16 / React 19.
• Architected an env-switched dual data source: 12 service-layer modules route at runtime between WordPress CMS and static fallback data behind a single feature flag.
• Built an end-to-end type-safe content pipeline: 50 WordPress schema types to generated types to 12 unit-tested anti-corruption mappers to domain types.
• Established a 55-test suite and achieved Lighthouse Accessibility 100 across all 12 routes on mobile + desktop, with Best Practices 96 and SEO 92.
