Results that shipped

  • Production downtime during migration

    Eliminated

    Stated outcome across the four extracted services over the migration. No incident count is published.

  • Services extracted from the monolith

    4

    Go services carved out of the PHP/MySQL monolith.

  • Peak-concurrency response delays

    Eliminated

    During peak concurrency, backend requests averaged 5-10 seconds before the migration. The migration eliminated those prolonged delays and improved throughput.

  • Streaming uptime

    ≥99.9%

    Sustained for 12+ months following launch.

  • Concurrent students served

    ~1,500(approx.)

    ~30 simultaneous classes at ~50 students each.

  • Status-update cycle

    6 hours → <1 minute

    Time for production status to reach stakeholders across ~3 plants and ~30 lines.

  • Data freshness

    ≤30 seconds

    Maximum age of data shown on the dashboard.

  • Manual data consolidation

    ~6-10 hrs/week → 0(approx.)

    Manual consolidation work removed by the unified dashboard.

  • Machines reporting telemetry

    >100 machines at ~150 msg/s(approx.)

    Machines integrated into the unified dashboard.

  • Uses agentic development workflows as a standard part of delivery, holding production-grade quality while shortening the path from proposal to shipped change.
  • Contributes to a mobile enablement initiative for a POS platform using .NET MAUI, porting core desktop workflows to mobile.
  • Implemented an LLM-powered data-processing flow using LangChain, integrated cleanly into existing service workflows.
