I Build
for the Web
Laravel & PHP developer with 8+ years. I build multi-tenant SaaS platforms, AI chatbots, REST APIs, and upgrade legacy PHP / CodeIgniter codebases — without downtime.
class SaasService { public function boot(): void { Laravel::version('12.x'); PHP::version('8.5'); AI::integrate('gpt-4o'); SaaS::multiTenant(true); } }
Technologies & Skills
Is Your App Running an Outdated PHP or Laravel Version?
PHP 5.x and 7.4 are end-of-life with known unpatched security vulnerabilities. Laravel 5–8 are no longer maintained. I upgrade legacy PHP, Laravel, and CodeIgniter projects to the latest secure versions — safely, without downtime.
What I Build For You
From idea to production — I handle the full development lifecycle. Here are the core services I offer to help grow your business.
AI Chatbot Development
Custom AI chatbots powered by GPT-4o, Claude, or Gemini — trained on your data using RAG pipelines, vector embeddings, and pgvector. I build multi-turn conversation flows and integrate them into any platform.
AI Integration into Existing Projects
Already have a Laravel, Vue.js, or PHP app? I add AI capabilities — smart search, content generation, data extraction, auto-classification, vector embeddings, and more — without rebuilding from scratch.
Vue.js & Nuxt.js Development
Fast, SEO-friendly frontends built with Vue.js and Nuxt.js — SSR, SSG, SPA, or hybrid. I build everything from marketing sites to complex SPA dashboards with real-time updates and smooth UX.
Livewire & Filament Development
Full-stack Laravel apps with reactive UIs using Livewire — no separate frontend build needed. I also build powerful admin panels and CRUD systems with Filament, including custom resources, widgets, and dashboards.
Upgrade Legacy PHP, Laravel & CodeIgniter Projects
Running PHP 5/7, Laravel 5–8, or CodeIgniter 2/3? Your app has known security vulnerabilities and is no longer receiving patches. I migrate legacy codebases to modern, secure versions — without downtime or data loss.
SaaS Platform Development
I build multi-tenant SaaS platforms from scratch — subscription billing, team management, RBAC, usage analytics, and self-service portals. Scalable Laravel architecture that grows with your business.
DevOps, CI/CD & Laravel Deployment
I set up professional DevOps pipelines for Laravel apps — Docker containers, GitHub Actions CI/CD, Laravel Forge deployments, server hardening, Redis, Horizon, and zero-downtime releases.
Laravel API Development
Clean, documented REST APIs built with Laravel — authentication, rate limiting, versioning, webhooks, and full OpenAPI documentation. Built to be consumed by mobile apps, SPAs, or third-party services.
Full Stack Web Development
End-to-end web application development — Laravel backend paired with Vue.js, Nuxt.js, Livewire, or React frontend. From business logic to pixel-perfect UI from Figma, I handle the full stack.
Payment Gateway Integration
Secure payment integrations for Laravel apps — Stripe, PayPal, Razorpay, and more. Subscriptions, one-time payments, invoicing, refunds, webhooks, and full PCI-compliant checkout flows.
About Me
I'm a Senior Full Stack Developer with 8+ years building production web applications. Currently working remotely as Senior Dev at Xcalibur Digital (Malaysia), I specialize in scalable SaaS platforms, robust APIs, and AI-powered applications.
My expertise spans the full development stack — from Laravel & PHP on the backend to Vue.js, Nuxt.js & React on the frontend. I've worked on everything from startup MVPs to enterprise multi-tenant platforms processing millions of records.
Real Problems. Real Results.
Not just code — business outcomes. Here's how I've helped clients solve real problems.
Multi-Tenant SaaS Platform Migration
A growing B2B startup had a single-tenant Laravel app collapsing under 3,000 users — one slow tenant degraded everyone. Manual onboarding took 45 minutes per client.
Rebuilt with multi-tenant row-level isolation using a custom Laravel tenancy layer. Extracted a self-service onboarding flow with automated provisioning.
Onboarding time dropped from 45 min → under 3 minutes. Infrastructure cost cut by 38%. Platform now handles 15,000+ tenants without degradation.
AI Support Chatbot with RAG Pipeline
A SaaS company's support team spent 6+ hours/day answering repetitive questions from the docs. Response time averaged 4 hours, causing churn.
Built a RAG-powered chatbot trained on their documentation, support tickets, and product FAQs. Integrated into their website and Slack workspace.
74% of support tickets deflected automatically. Average response time: instant. Support team now focuses on complex issues only.
Legacy PHP 5.6 → Laravel + PHP 8.x Modernization
A 7-year-old CodeIgniter 2 app on PHP 5.6 — no tests, no CI/CD, 2-hour deployments, and a team afraid to touch the codebase.
Phased migration to Laravel + PHP 8.x. Added Pest test suite covering 85% of critical paths. Set up GitHub Actions CI/CD pipeline.
Deployment time: 2 hours → 9 minutes. Zero critical bugs since go-live. Team velocity tripled in the first sprint.
