BULLETPROOF INFRASTRUCTURE.
Order & Inventory Sync (OMS)
Automate synchronization across Shopify, multiple marketplaces, and offline POS systems. We build event-driven engines that manage stock allocations, dynamic reservations, and split-routing logistics in real-time.
- Multi-channel inventory mapping
- Automated split-shipment rules
- Real-time stock ledger tracking
- Custom warehouse API integration
Product Information Management (PIM)
Establish a single source of truth for global product data. Our custom PIM architectures centralize SKU information, assets, localized translation workflows, and multi-tier pricing structures.
- Bulk catalog schema editors
- Localization & translation pipelines
- Automated syndication feeds
- High-fidelity digital asset handling
Custom Dashboards & Internal Tools
Stop running your business on generic spreadsheets. We design high-fidelity administrative panels, customer support consoles, and shipping queues perfectly tailored to your warehouse operation teams.
- Role-based access control (RBAC)
- Real-time transactional reporting
- Custom bulk import/export utilities
- Instant log audit trails
Middleware & Serverless Pipelines
Secure, highly-resilient API integration layers. We build modern middleware to bridge modern storefronts with legacy enterprise ERPs, featuring automatic queue retries and robust error handling.
- SAP, NetSuite, & Dynamics bridges
- Event queueing (RabbitMQ / SQS)
- Serverless auto-scaling compute
- Zero-data-loss transaction logging
ENGINEERING STACK.
We build on cloud-native databases, event-driven message queues, and bulletproof relational structures to guarantee zero-data-loss and absolute consistency.
// single UPDATE eliminates TOCTOU — atomic, one round trip
func (s *InventoryService) Reserve(
ctx context.Context,
sku string, qty int,
) error {
const q = `
UPDATE inventory
SET available = available - $1,
reserved = reserved + $1
WHERE sku = $2
AND available >= $1
`
res, err := s.db.ExecContext(ctx, q, qty, sku)
if err != nil {
return err
}
if n, _ := res.RowsAffected(); n == 0 {
return ErrInsufficientStock
}
return nil
}
FREQUENTLY ASKED QUESTIONS.
Why do we need a custom Commerce System instead of just using standard Shopify apps?
While Shopify apps are great for basic needs, they run on shared infrastructure, are limited by Shopify's API rate limits, and fragment your business data across dozens of third-party servers. A custom Commerce System built by Hakooi centralizes your business logic and data. It allows you to run complex inventory allocation algorithms, handle massive transaction volumes without rate limiting, and interface securely with legacy enterprise software under your own infrastructure.
What database and server architectures do you use for these engines?
Our technology choices are driven by each system's performance profile. For high-throughput order sync engines and inventory daemons, we use Golang — its concurrency model is purpose-built for processing thousands of simultaneous events with minimal CPU overhead. For convention-driven admin APIs and back-office tools, we use Ruby on Rails for its battle-tested reliability. Data is persisted in PostgreSQL with Redis handling sub-millisecond state caching, hosted across auto-scaling cloud infrastructure on AWS.
Can you integrate older, legacy ERP systems like Microsoft Dynamics or SAP?
Absolutely. We specialize in building secure, resilient middleware bridges. Since legacy ERPs often lack webhook support or modern REST architectures, we build custom sync daemons or serverless polling pipelines that translate modern webhook events from your storefront into secure, batch-processed files or XML/SOAP payloads accepted by your legacy corporate ERP, complete with robust failure alerts.
How do your systems handle high-concurrency flash sales events?
We prevent database crashes by separating the ingestion layer from the writing layer using asynchronous messaging queues (like AWS SQS or RabbitMQ). If 10,000 customers place an order in the same second, the storefront quickly acknowledges the request, places it into a highly scalable queue, and background workers process the orders at a safe, continuous rate, protecting your backend ERP from collapsing under sudden load.
