Case Studies
Real projects, real results — see how we've helped companies build scalable payment systems, high-performance platforms, and mission-critical infrastructure
Payment Infrastructure Migration
ChargeOver → Stripe Billing
Client
Financial Platform (USA)
Tech: Stripe Billing, ACH, PHP 8, Laravel, Redis, AWS
Challenge
The company relied on an outdated billing system (ChargeOver), with recurring errors, rigid API capabilities, and low payment recovery rates. They needed a modern payment stack with ACH, subscriptions, proration, retries, and full automation — without downtime.
Solution
We architected a complete Stripe migration:
- Modeled products, prices, and subscription lifecycles
- Built an adapter-based payment orchestration layer
- Implemented ACH onboarding & micro-deposit verification
- Created resilient webhook handlers with retries + idempotency
- Designed payout routes for multi-party financial flows
Results
Real-Time Inventory Platform for Retail
2,000+ SKU Custom ERP/Cloud Sync
Client
Retail / eCommerce
Tech: Laravel, Redis, MySQL, Cloud + Local Sync
Challenge
Retailers needed a system to manage >2000 SKUs across both cloud and local stores, with real-time sync and fail-safe operations.
Solution
We delivered a high-performance inventory engine:
- Modular architecture
- Delta-based sync between cloud & POS
- Conflict resolution for concurrent updates
- Near-instant stock adjustments with Redis caching
Results
Policy Management System for Insurance
Microservices + Event Architecture
Client
Insurance Platform
Tech: PHP 8, Laravel, Redis, AWS, Microservices
Challenge
Client needed a scalable, modular system to manage thousands of insurance policies: updates, renewals, events, customer-facing portal.
Solution
We built:
- Microservices architecture for policy management
- Automated workflows for renewals & compliance
- Customer portal for policy updates
- Secure document processing + auditing
Results
System Architecture
Modular, scalable architecture
Real-time policy updates
Full compliance tracking
Backend Platform Rewrite & High-Volume Content Processing
High-Performance Parsing, Asynchronous Workflows
Client
Content Syndication / eCommerce Integrations
Tech: PHP, REST APIs, Job Queues, Asynchronous Workers
Challenge
The platform processed large product data feeds for global retail integrations, but suffered from slow ingestion, blocking operations, and bugs that intermittently disrupted SLAs.
Solution
I rebuilt and optimized critical backend systems:
- Refactored the feed ingestion engine
- Reduced memory usage and improved throughput
- Implemented asynchronous job queue architecture
- Added robust retry + recovery logic
- Improved error handling and operational visibility
- Delivered additional modules such as feedback and payment integrations
Results
Key Improvements
Optimized feed processing
Async job queue architecture
Enhanced customer satisfaction
Lending Platform Modernization & Architecture Upgrade
Platform Migration, System Architecture, Engineering Processes
Client
Financial Services
Tech: .NET, PHP, Redis, CI/CD (Jenkins, Docker, Puppet)
Challenge
A national-scale lending platform operated a monolithic legacy system with weak development processes, difficult deployments, and a roadmap blocked by technical debt. The platform needed a migration plan to a modern architecture and a fully redefined engineering workflow.
Solution
I led the system redesign and platform modernization initiative:
- Defined the full architecture for service decomposition
- Created domain boundaries and data flow diagrams
- Built transitional services enabling gradual migration
- Introduced CI/CD pipelines and standardized release processes
- Established documentation, coding practices, and cross-team workflows
- Integrated Redis for caching and performance improvements
Results
Transformation Outcomes
Scalable modern architecture
Company-wide adoption
Improved reliability
Better performance & maintainability
