— Upwork client, 5-star review
I'm a backend developer with 9+ years of experience. I build in PHP/Laravel and Perfex CRM, and I've built production platforms in Node.js, Next.js, and Go. If you need backend work done properly — in an existing codebase or from scratch — that's what I do.
============ PLATFORMS I'VE BUILT ============
WHATSAPP MESSAGING PLATFORM (Node.js, Next.js, Redis, PostgreSQL) :
Built the backend for a WhatsApp Business messaging platform — Redis for message queuing and caching, PostgreSQL for message, contact, and campaign data, and Next.js for the dashboard. Handles real-time message flow, delivery tracking, and high-volume sending without dropping messages.
SOCIAL PLATFORM BACKEND (Go / Fiber, PostgreSQL) :
Built REST APIs and real-time features for a social platform using Go with the Fiber framework — high-throughput endpoints, PostgreSQL data layer, and the concurrency handling that social
feeds and messaging demand.
PERFEX CRM CUSTOMIZATIONS (PHP, MySQL) :
Years of custom module development, integrations, and version upgrades on Perfex CRM installations that businesses run their daily operations on.
============ WHAT I DO ============
BACKEND DEVELOPMENT:
- REST APIs in Go (Fiber, Gin), Node.js (Express), and Laravel
- Real-time systems — queuing, caching, message delivery
- Database design and optimization — PostgreSQL and MySQL
- Performance work — slow queries, missing indexes, caching strategy
- Third-party API integration and webhook handling
PERFEX CRM (my longest specialty):
- Custom modules — built as standalone modules, never core-file hacks, so your customizations survive version updates
- Bug fixes — errors after updates, module conflicts, broken features
- Custom reports and dashboards for your specific workflow
- Theme changes, PDF templates (invoices, estimates), and email templates
- Version updates with your existing customizations preserved
- Workflow automation — reduce the manual steps your team repeats daily
PHP & LARAVEL:
- Web application development, maintenance, and bug fixing
- Legacy PHP and CodeIgniter upgrades and migrations
- Admin panels, business logic, role-based access
FRONTEND (where a project needs full-stack):
- Next.js — auth, dashboards, API integration
- Vue.js and React for admin interfaces
INTEGRATIONS:
- Payment gateways — Stripe, PayPal, Authorize.net
- Accounting tools — Xero, MYOB
- Marketing platforms — Hubspot, Mailchimp
- WhatsApp Cloud API and custom third-party APIs
============ HOW I WORK ============
- Plan first — I confirm exactly what I'll change and what I need from you before touching your system
- Staging-first — if it's running your business, I work on a copy where possible and never leave your live system broken
- Update-safe by design — custom work goes in separate modules, documented clearly where core changes are unavoidable
- Small, reviewable changes — I'd rather ship in reviewable pieces than drop one large untested change at the end
- Scope honesty — if a request is bigger than what you paid for, I'll tell you before starting, never after
- Clear communication — my clients specifically mention it in their reviews
============ WHY ME ============
- 9+ years of backend development across PHP, Node.js, and Go
- Production platform experience, not just tutorials — real systems handling real traffic with Redis, PostgreSQL, and real-time requirements
- Multiple 5-star reviews on Perfex CRM projects ("Great job!" — another happy Perfex client)
- I work across stacks, so I can maintain your existing PHP system and build your new Go or Node service
============ LET'S TALK ============
Message me with what you need built or fixed — a Perfex customization, a PHP application, a Node or Go backend, or something you're not sure how to scope yet. Even a couple of sentences and a screenshot is enough. I'll reply within a few hours with a clear plan and an honest timeline.

Review & Plan
I review your request, your Perfex version, and installed modules, then confirm exactly what I'll change, the timeline, and anything I need from you — before touching your system.
Development on Safe Copy
I build the fix, module, or customization — working on a staging copy or backup where possible, so your live CRM keeps running normally throughout.
