Problems I Solve

When an off-the-shelf solution is not enough for the technical problem

  • ERR 01

    Cart and checkout failures

    Sessions, gateways, validation and custom checkout logic

  • ERR 02

    Order, price and inventory mismatches

    Data flow with ERP, CRM and warehouses, with logging and retries

  • ERR 03

    Legacy and incompatible plugins

    PHP and WooCommerce compatibility, less technical debt

  • ERR 04

    Slow and difficult production errors

    Queries, cron, Action Scheduler and cache, to the root cause

Collaboration Process

First we define the problem precisely, then we touch the code

  1. Hearing the problem

    What is broken, since when, and what access is needed.

  2. Finding the root cause

    Code, data and runtime behaviour, until the real cause shows up.

  3. Agreeing on the path

    Scope, risks, and what "done" will mean.

  4. Delivery and handoff

    Tested changes, with a report you can still use later.

Professional Collaboration

If you have a specific technical problem, let us start from that problem.

For a technical assessment, a complex fix, plugin maintenance, or specialist team support, send the project context. After the initial review, I will clearly suggest the most suitable next step.
