CHALLENGE

A promising idea, but outsourcing to a development firm was too expensive. With no in-house engineers hired yet, they needed a working demo for investors—on a tight deadline.

SOLUTION

Handled everything from requirements to implementation. Built a web app with embedded AI features on Next.js + Cloudflare Workers, delivering the prototype in 3 weeks. Continued with monthly improvement support after launch.

OUTCOMES

  • Cost reduction

    1/5 to 1/10 vs. traditional firms

  • Prototype delivery

    3 weeks from confirmed requirements

  • Investor demo

    Completed on time, accepted

CHALLENGE

Client communications, document requests, and confirmations were all managed manually via email and spreadsheets—consuming 20+ hours of checking work each month-end, with frequent human errors.

SOLUTION

Built a client-facing web portal handling document uploads, status tracking, and automated reminders. Integrated AI-based input validation and Slack notifications to minimize manual checking.

OUTCOMES

  • Monthly checking work

    20 hrs → 4 hrs (≈80% reduction)

  • Human errors

    Near zero

  • Client satisfaction

    Significantly faster response times

CHALLENGE

Inventory was managed in spreadsheets with no sync between EC and physical store—leading to repeated ordering errors, excess stock, and a full-day monthly inventory check.

SOLUTION

Built a custom inventory management system. Real-time API integration with Shopify and in-store POS auto-generates purchase orders when stock drops below threshold, with a unified dashboard for visibility.

OUTCOMES

  • Ordering errors

    Reduced to zero

  • Monthly inventory check

    1 day → 1 hour (≈85% reduction)

  • Inventory turnover

    Improved through reduced excess stock
