About

Full-stack web developer with 6+ years of production experience shipping client websites, now focused on Vue/Nuxt + Postgres applications. I design and run a multi-tenant SaaS platform covering authentication, payments, scheduling, document ingestion, and a Capacitor-based Android tracker — all on a single Nuxt 4 codebase backed by Supabase Postgres with row-level security.

✎ 6+ years, multi-year client relationships.

✎ Takes projects beyond WordPress when they outgrow it.

Skills

Frontend

Vue 3 (Composition API) Built 40+ reusable components and composables across the dashboards.Nuxt 4 The whole platform — pages, SSR, and server routes — runs on one Nuxt 4 app.TypeScript End-to-end types shared across the frontend, server routes, and data layer.Tailwind CSS v4 Token-based theming so each role’s dashboard has its own consistent look.Nuxt UI Accessible base components for forms, modals, and data tables.Vite Fast HMR in dev and optimized, code-split bundles in production.PWA (Workbox) Offline shell and install prompts via @vite-pwa/nuxt.Service Workers Cache the app shell and assets so dashboards load offline.IndexedDB Pending-queue for GPS fixes so no lesson route is lost on a crash.Geolocation API watchPosition powers live trip tracking in the browser runtime.Wake Lock API Keeps the screen awake while an instructor records a route.SSR / hybrid rendering Server-render marketing pages for SEO; hydrate dashboards behind auth.

Backend

Nitro server routes Every API — auth, payments, document ingest — is a Nitro server route.Node.js Server runtime for APIs, cron jobs, and the IMAP poller.REST APIs Designed the platform’s REST endpoints with role-based guards.Cron jobs Schedule the inbound-email poller and routine maintenance tasks.Webhooks Handle Resend Inbound and Moneris callbacks as server webhooks.Server middleware Adds security headers and CSRF before every request.PL/pgSQL functions & triggers Audit-ledger trigger mirrors every transaction into a tamper-evident table.Realtime / WebSockets Stream live trip playback and notifications to clients.PDF extraction (unpdf) Pull text from forwarded receipts and certificates for ingest.Email parsing (mailparser) Normalise inbound emails into one shape for the pipeline.Image processing (sharp) Resize and compress avatars and uploaded documents.Idempotency keys Stop double-clicks and retries from recording a payment twice.CSV export Admin data exports for reporting and bookkeeping.

Database

Postgres Primary datastore — schema, triggers, indexes, and JSONB columns.Supabase Managed Postgres + Auth + Storage + Realtime backing the platform.Row-Level Security Per-role RLS policies so the database itself enforces access.JWT custom claims A claims hook injects the user’s role into every token for RLS.SQL migrations 60+ versioned migrations run through the Supabase CLI workflow.Postgres triggers Immutable audit trail and derived-balance maintenance.Supabase Storage Holds avatars and student documents with scoped access.Supabase Realtime Publications and channels drive live trip and notification streams.GRANT / least-privilege Revoke anon/authenticated on admin-only tables beyond RLS.node-postgres (pg) Direct Postgres access for scripts and migration tooling.Schema design Modelled enrolments, ledgers, documents, and lesson data.MySQL Data management during my early work at 7th Pixel.

Auth & Security

Supabase Auth Sign-up, login, sessions, and password reset for all roles.CSP + nonce Per-request nonce CSP emitted by nuxt-security.strict-dynamic Only scripts the app loads can execute, even if markup is injected.CSRF Custom double-submit CSRF on every mutating request.Rate-limiting IP + session limits on public and auth endpoints.reCAPTCHA v3 Server-verified bot scoring on public forms.Role-based access Student / parent / instructor / admin enforced in three layers.HSTS / security headers HSTS preload, nosniff, framing, and Permissions-Policy locked down.Honeypot + dwell-time Catch bots that fill hidden fields or submit suspiciously fast.IDOR prevention Ownership checks so an ID can’t be guessed to reach another account.Account lifecycle / soft-delete Archived/deleted accounts are rejected even with a valid token.

Integrations

Moneris Checkout Hosted Checkout with server-to-server verify and an audit ledger.Resend Transactional email for verification, receipts, and notifications.Resend Inbound Webhook transport that feeds the document-ingest pipeline.IMAP (imapflow) Polls a mailbox to ingest forwarded registrations and receipts.Leaflet Live trip map with animated polyline playback over Realtime.OpenStreetMap / CARTO Basemap tiles for the trip map, with OSM as fallback.Interac e-Transfer Claim and reconciliation workflow for non-card payments.

Mobile / Native

Capacitor 6 Wraps the same Nuxt app as an Android GPS lesson tracker.Android Shipped the single codebase as an installable Android APK.Java Native glue for the Android foreground-service integration.Gradle Android build configuration and dependency management.Foreground service Keeps GPS tracking alive with the screen off in a moving car.Background geolocation @capacitor-community/background-geolocation for field recording.Offline-first sync Buffer fixes locally and replay them once the network returns.

DevOps / Quality

Git Version control for everything I ship.Supabase CLI Runs migrations and the local Postgres stack for safe changes.Docker Runs the local Supabase stack for sandboxed development.Playwright (E2E) Regression harness covering auth, role gating, and payments.ESLint Enforces consistent style and catches issues before commit.Sandbox / prod env switching One command flips between local sandbox and cloud, with guard rails.SEO (Schema.org · Sitemaps · OG) Structured data, sitemaps, and social cards for the public site.WebP optimization Compressed, responsive images for fast page loads.

Tooling & WordPress

Elementor Built the original Driving Headquarters WordPress site.Divi Designed Tamil Heritage Month end-to-end in the Divi builder.WP Rocket Caching + CDN for WordPress performance tuning.Wordfence Security hardening and login lockdown on WordPress sites.UpdraftPlus Scheduled backups and restores for WordPress clients.All-in-One SEO On-page SEO, sitemaps, and meta management in WordPress.

Featured Project

Driving Headquarters Platform

2022 — Present · Live in production

A single-codebase web + mobile platform: public marketing site, four authenticated dashboards (student, parent, instructor, admin), a payments + financial-ledger system, an email-driven document-ingest pipeline, and a live GPS lesson tracker.

01

Three-layer authorization

Role-based access enforced in client route middleware, server requireAuth/requireRole guards, and Postgres RLS policies driven by a JWT custom-claims hook — a leaked service key still cannot bypass it.

02

Cloud payments pipeline

Moneris Hosted Checkout with server-to-server verify, an immutable transaction audit trigger, payment-plan modelling, and an e-Transfer claim/reconciliation workflow.

03

Document-ingest pipeline

Forwarded emails (BDE receipts, MTO certificates, driver licences) auto-route to the right student via per-kind extractors, content-fingerprint dedup, and a fuzzy student matcher.

04

Live GPS trip tracker

Capacitor background-geolocation as an Android foreground service with offline buffering, played back on a Leaflet map over Supabase Realtime.

05

Hardened public surface

nuxt-security CSP (per-request nonce, strict-dynamic), custom CSRF middleware, IP+session rate limiting, reCAPTCHA v3, honeypot, and dwell-time bot defence.

06

Safe database operations

60+ versioned SQL migrations via the Supabase CLI workflow, a sandboxed local Postgres, and a Playwright QA harness that runs a full regression pass before any deploy.
