Real production issues encountered and resolved during customer deployments.
Integration Crisis Recovery
Customer's ERP crashed during go-live. Implemented emergency backup sync mechanism using CSV exports + API uploads.
Real-time API sync with customer's ERP system failed during go-live weekend. Built alternative data ingestion path to keep operations running.
Performance Optimization
Customer experiencing 30-second page load times with 500K SKU catalog. Implemented database indexing, query optimization, and caching layer, reducing load time to <2 seconds.
- ▹ Database indexing on frequently queried columns
- ▹ Query optimization to eliminate N+1 patterns
- ▹ Caching layer implementation
- ▹ Result: 30 seconds → <2 seconds page load time
Data Migration Challenge
Legacy system had 15 years of inconsistent data formats. Built Python scripts to clean, normalize, and validate 2M+ records, achieving 98.8% data accuracy post-migration.
- ▹ 2M+ records with inconsistent formats across 15 years
- ▹ Built ETL pipeline for cleaning and normalization
- ▹ Achieved 98.8% data accuracy post-migration
Warehouse Migration
Customer moved between two warehouses over the weekend. Helped them move, clean-up, upload the new warehouse data, keeping operational aspects running without any interruptions.
On-site support during weekend warehouse relocation to ensure system data stayed synchronized with physical inventory movement.
Measurable operational improvements delivered to strategic customers.
Reduced order processing time from 10 minutes to 2 minutes per order for 3PL customer processing 10K+ orders/day
Enabled through AI-powered optimization algorithms (box and carrier selection, order batching, routing optimization)
Supported and guided Alcohol & CCPA compliance implementation that unlocked market expansion for fulfillment brand
Improved from 85% through cycle counting automation and real-time tracking
