Selected Shipped Systems
A deep-dive review of custom modules and systems architected for reliable scale and clear real-world performance.
Warehouse Management System
Challenge:
Managing and coordinating warehouse inventory logs manually, resulting in structural data errors, supply delays, and untraceable workflow logs.
Solution:
Developed a robust real-time warehouse registry system with automated workflow triggers, dynamic stock checklists, and synchronized API queries.
Results:
- Reduced manual administrative effort by over 70%
- Drastically improved real-time inventory tracking accuracy
- Structured automatic reports generation with dynamic database sync
HRMS & CRM Modules
Challenge:
Siloed workflows and data mismatches between sales pipelines and internal human resources logs, causing manual transfer bottlenecks.
Solution:
Decoupled backend operations into standalone modular CRM (lead tracking) and HRMS (payroll, logs) components, synchronizing workflows in real time.
Results:
- Completely eliminated manual CSV formatting and imports
- Decreased general administrative processing times by 35%
- Established real-time role-based access for team leads
Wallet Management System
Challenge:
Synchronizing user digital balances securely with volatile, real-time external trading platforms while preventing negative ledger states.
Solution:
Built a secure ledger server communicating directly with the MetaTrader 5 API, backed by automated KYC flows using Sumsub.
Results:
- Eliminated double-spend and balances reconciliation mismatches
- Automated user validation checks, speeding up approvals
- Secure transaction registries handling high throughput
