INDEPENDENT / B2B

Senior PHP / Laravel Engineer

Independent engineering and architecture for business applications, alongside ongoing development of OHLC Bot, a private project for market data, automation and analytics. My current stack includes PHP 8.5 and Laravel 13.

  • Backend architecture, data modelling, permissions, reporting, invoicing and document processing across PHP / Laravel and Yii2 applications.
  • REST API, webhook, SFTP and digital-signature integrations, including solutions within legacy platform constraints.
  • OHLC Bot: market-data processing, exchange API integrations, scheduled automation and operational dashboards.
  • Reliable automated workflows through transactional data handling, idempotency, concurrency controls and careful failure handling.
  • Interactive web dashboards and Android app integration using JavaScript, Bootstrap, Vite and Capacitor.
  • Regression and mutation testing, static analysis and browser checks, supported by CI automation and operational monitoring.
  • AI-assisted development with OpenAI Codex: structured specifications and a main agent supporting planning, task decomposition, technical context and integration.
  • Multi-agent coordination: a dedicated coordinator tracks tasks and dependencies, a communication bridge carries context and handoffs, and multiple specialist agents work on scoped implementation, testing and independent review.
  • Parallel delivery with isolated workspaces, explicit ownership, review feedback loops and reproducible validation. I retain responsibility for technical decisions, release approval and the final result.
