01 · The Context & Challenge

Fleet operators were running tracking, driver management and violation monitoring across disconnected tools. Growing the product meant per-client deployments: every new fleet customer cost another install, another migration, another support surface. The system needed to become a shared platform without giving any client access to another's data.

02 · Technical Contributions

  • Lead full-stack development of the platform, directing architecture decisions end to end — database design through CI/CD deployment on AWS.
  • Designed the multi-tenancy architecture that reduced per-client deployment overhead and simplified onboarding of new fleet customers onto a shared platform.
  • Own end-to-end delivery of real-time coaching and chat features built on WebSockets, improving driver responsiveness and reducing incident review time for fleet managers.
  • Drive technical direction for the team — code reviews, Laravel/Vue.js coding standards, and mentoring mid-level developers.

03 · Architectural Highlights

Multi-tenant by design

A single shared platform serves multiple client fleets. Onboarding a new fleet customer became a configuration task instead of a deployment project.

Real-time operations layer

Driver coaching and chat run on WebSockets — dispatchers and fleet managers act on live state instead of reviewing incidents after the fact.

Self-hosted AI coaching

Prototyping AI-driven driver-coaching features with open-source LLMs served through Ollama and ONNX Runtime — a self-hosted alternative to third-party AI APIs.

Delivery pipeline

Owns the path from database schema to CI/CD deployment on AWS for the whole team.

05 · Measurable Outcomes

  • A shared multi-tenant platform serving multiple client fleets, with per-client deployment overhead designed out.
  • Real-time coaching and chat that improved driver responsiveness and reduced incident review time for fleet managers.
  • A team with set coding standards, regular reviews, and mentoring for mid-level developers.
