Tech Disciplines

Laravel / SaaS

Multi-Tenant SaaS Platform

Problem

Client needed a subscription SaaS that could isolate data per tenant, support white-labelling, and scale to hundreds of concurrent accounts without per-customer infrastructure.

Solution

Multi-tenant Laravel platform with per-tenant DB isolation, Filament super-admin and tenant-admin dashboards, Stripe subscription billing, subdomain routing, and Docker + GitHub Actions CI/CD.

Results

✓ 99.95% uptime since launch
✓ 500+ active tenants
✓ Stripe billing fully automated
✓ Zero-downtime deployments

→ SaaS Development Service

ERP / Enterprise

Enterprise ERP System

Problem

A 200+ employee manufacturing company operated three separate legacy systems (HR, inventory, finance) that required daily manual reconciliation and produced inconsistent reports.

Solution

Single unified Laravel ERP replacing all three systems — HR with payroll and attendance, inventory with supplier management and purchase orders, and real-time financial reporting with BI dashboards.

Results

✓ 3 legacy systems replaced
✓ Real-time financial reporting
✓ Automated payroll processing
✓ Role-scoped access for 5 departments

→ CRM/ERP Service

WordPress / Plugins

Commercial WordPress Plugin Suite

Problem

Client required a suite of commercial WordPress plugins — booking, membership, WooCommerce extensions — sold via CodeCanyon and direct, with recurring license management.

Solution

OOP plugin architecture across 15+ plugins: advanced booking with calendar and payment integration, membership manager, WooCommerce subscription extensions, and Gutenberg custom blocks. License enforcement via update API.

Results

✓ 15+ plugins shipped
✓ Consistent update delivery
✓ WooCommerce-compatible
✓ WordPress coding standards compliant

→ WordPress Plugin Service

Android / Kotlin

Native Android E-commerce App

Problem

Client had a Laravel-based online store but no mobile presence. Needed a native Android app with real-time order tracking, offline capability, and Firebase push notifications.

Solution

Native Kotlin app with MVVM architecture, Retrofit API layer consuming the existing Laravel REST API, Room database for offline order history, Firebase Cloud Messaging for push notifications, and Google Play deployment.

Results

✓ 10,000+ installs on Google Play
✓ 4.7★ user rating
✓ Full offline order history
✓ Push notification open rate: 34%

→ Android Dev Service

DevOps / CI/CD

Zero-Downtime Deployment Pipeline

Problem

Deployments took 2+ hours, required manual SSH steps, and caused downtime. The team was blocked from shipping multiple times per week due to deployment risk.

Solution

GitHub Actions CI/CD pipeline with automated PHPUnit testing, code quality gates, blue-green deployment to AWS EC2, health-check triggered rollback, and Slack deployment notifications.

Results

✓ Deploy time: 2 hours → 4 minutes
✓ Zero production downtime since launch
✓ Automated rollback on failure
✓ Daily deploys enabled

→ DevOps Service

Python / Data

Large-Scale Data Pipeline

Problem

Client needed to collect, clean, and load product and pricing data from 50+ e-commerce sources daily — manually operated scraping scripts were unreliable and unscalable.

Solution

Distributed Scrapy spider architecture with proxy rotation, Celery task queue for parallel crawling, PostgreSQL storage with deduplication, daily automated cleaning pipeline with Pandas, and a simple reporting dashboard.

Results

✓ 1M+ records processed daily
✓ 50+ sources crawled
✓ Deduplication automated
✓ Daily report delivered automatically

→ Python Automation Service

CRM / Sales

Custom Sales CRM Platform

Problem

A 50-person sales team was paying for Salesforce but using only 20% of its features, while lacking several capabilities specific to their sales motion. Onboarding new reps took weeks.

Solution

Purpose-built Laravel CRM with lead scoring, deal pipeline, task automation, email thread integration, role-based dashboards for reps, team leads, and management, and a public API for third-party integrations.

Results

✓ Salesforce licence cost eliminated
✓ Rep onboarding: 3 weeks → 3 days
✓ Deal pipeline accuracy improved
✓ Custom reports on demand

→ CRM/ERP Service

WordPress / API

Headless WordPress CMS

Problem

Client's traditional WordPress site was slow, difficult to theme consistently, and couldn't serve content across multiple frontend apps. Editors needed to keep WordPress as the CMS.

Solution

Decoupled WordPress setup with custom REST API endpoints, ACF Pro for structured content, JWT authentication, and a Nginx reverse proxy serving the headless backend. Frontend team consumed the API independently.

Results

✓ 3× faster page load
✓ API consumed by 2 frontends
✓ Editors kept familiar WP interface
✓ REST API documented with Swagger

→ WordPress Service

Growth / Analytics

E-commerce Conversion & Analytics

Problem

WooCommerce store had significant traffic but a 1.2% conversion rate. No funnel visibility, no A/B testing infrastructure, and no understanding of why users dropped off at checkout.

Solution

GTM implementation with custom e-commerce event tracking, checkout funnel analysis, server-side event logging, automated weekly cohort reports via Python + Google Sheets API, and checkout UX fixes informed by data.

Results

✓ CVR: 1.2% → 3.8%
✓ Checkout abandonment reduced 40%
✓ Weekly automated revenue reports
✓ Attribution model established
