Nearly five years building and owning production Laravel systems, with a focus on backend architecture, financial and operational modules, and API infrastructure.

The path: early engineering hire on a greenfield platform, then sole full-stack developer across multiple independent client products, then owner of the Finance, HR, and Payroll domains on a production insurance platform, working directly with executive and business stakeholders.

Most of my work is taking a module from ambiguous requirements through data modeling, backend logic, and UI, and fixing the security and performance problems I find along the way.

Backend     PHP 8, Laravel, RESTful API design, Eloquent ORM, MySQL, schema design,
            middleware architecture (caching, rate limiting, security, monitoring)
Frontend    Livewire, Alpine.js, Vue.js, Tailwind CSS, Bootstrap
Admin/Tool  FilamentPHP (including a v4 migration on a large production codebase)
Infra       Redis-compatible caching, AWS S3 via Flysystem, Git/GitHub
Security    Role-based access control, XSS mitigation, SQL injection remediation,
            secrets management
Stack       TALL (Tailwind, Alpine.js, Laravel, Livewire)
Learning    React 19 + TypeScript with Inertia, on my own portfolio build

Sole engineer for Finance, HR, and Payroll on the company's Takaful Management Solution, within a team of three engineers and two interns. Gathered requirements directly from the CEO, CTO, and Finance/HR leadership.

• Owned the Finance module end to end: chart of accounts, bank reconciliation, cheque books, budgets, fixed assets, vendor bills, purchase orders, and payments, including a legacy account-code format migration with data conversion and a balance sheet / trial balance reconciliation fix
• Owned HR and Payroll: payroll records and payments, deductions, advance salaries, employee management, biometric attendance integration, and a self-service employee portal with finance and HR reporting
• Designed and built the API caching, rate-limiting, security, and performance-monitoring middleware suite from scratch, applied across the customer and agent facing API layer to cut redundant database load on high-traffic endpoints
• Led a security hardening initiative: removed a hardcoded API secret that was leaking into server logs, closed a stored XSS gap with allow-list HTML sanitization, replaced raw SQL string interpolation with parameterized queries, and stripped sensitive data from application logs
• Built a deployment-independent role resolution service so HR and payroll notification logic no longer depended on hardcoded role names, letting the same code run correctly across environments
• Designed and built the original underwriting module from the Directors' approved requirements, then handed it off to other developers as its scope grew

Sole full-stack developer across two independent client engagements running in parallel.

• Consumer platform client: engaged for frontend fixes, then led a full migration of the frontend from Bootstrap to Tailwind CSS and Alpine.js. Promoted to sole full-stack developer with ownership of three concurrent Laravel platforms, each built end to end: schema and data model design, backend business logic, admin tooling, and user-facing views, with S3-backed media handling and third-party image-processing integrations
• Logistics client: sole developer (the client contributed under 5% of the code) building a trucking and logistics management SaaS from the ground up on the TALL stack: multi-step company onboarding, truck and driver registration, driver assignment, dispatch management, load and shipment tracking, and route management. Brought it through MVP; the engagement paused after 8-10 months when the client's priorities shifted, ending on good terms

Dec 2021 - May 2023

Joined a greenfield Laravel field-operations and auditing platform within its first week as an early engineering hire, alongside the founding developer and a scheduling-package specialist. Became the platform's sole engineer after the founder stepped back from code roughly four months in, and carried the codebase independently for the rest of the engagement.

• Owned the Livewire component layer, core models, migrations, and controllers, and designed the schema and domain model for the platform's core entities: activity orders, dashboard tiles, audit codes, filtered reporting, and task management
• Identified and independently fixed an unauthorized file-access vulnerability by building a dedicated media-access controller, without being assigned a ticket for it
• Built the reporting and export system across activity, audit, user, and permission data, and automated recurring report generation and activity reminders
• Integrated a third-party scheduling package into mail-based reminders and report triggers
