Selected Work

Supplier Catalog Automation

Problem

  • Supplier analysis relied on repetitive processing of large CSV and Excel files across multiple data providers.
  • Processing was slow, error-prone, and could not run continuously.

Solution

  • Built a full-stack application for data extraction, file ingestion, mapping, and processing.
  • Background workers handled file parsing, external API requests, automated calculations, and document generation.

Impact

  • 10× — Higher processing throughput
  • 24/7 — Continuous production workflow
  • Deterministic — Consistent processing with less manual intervention

  • PostgreSQL
  • Redis
  • Docker

Knowledge Support System

Problem

  • The existing third-party chatbot lacked sufficient company context and required an ongoing subscription.
  • The support team struggled to keep up with incoming requests during high-volume periods.
  • Visitors often had to wait for an available agent, even for common questions.

Solution

  • Collected, normalized, and indexed company content to build a retrieval-augmented support system.
  • Integrated existing authentication mechanisms to identify returning users and preserve conversation context.
  • Automated first-line support while keeping human escalation available when needed.

Impact

  • ~90% — Lower recurring support costs
  • 24/7 — Automated first-line support
  • Lower Load — Reduced routine support workload
