Earlier

### Earlier Roles

Previous positions: full-stack engineer at OMNI Solution (06/2020 – 11/2021) on PHP Laravel, web APIs and Flutter apps, including large-database optimisation; freelance full-stack developer from 2015 to 2020 on projects from small to large, mostly PHP (Zend, CakePHP, CodeIgniter, custom WordPress) with some Python, Node.js and Vue.js; and from 2011 to 2014, PHP developer, then senior developer and project manager, at three software companies.

## What I Can Help With

### [Backend Engineering](https://tmtuan.dev/en/services/backend-development)

Building backends and APIs for business systems and high-traffic platforms, keeping data correct and responses fast through query tuning, caching and background jobs for heavy work. Examples: Dr.Well-B, TaxPal, and a Beacon platform that has handled 761,921 device connections in a single hour.

### [Cloud Infrastructure](https://tmtuan.dev/en/services/gcp-cloud-infrastructure)

Provisioning and managing GCP and AWS infrastructure in Terraform, so every environment can be reviewed and recreated. IAM, secrets, CI/CD and monitoring are in place from day one, which makes each release routine work rather than a risk.

### [Production Troubleshooting](https://tmtuan.dev/en/services/production-troubleshooting)

Finding the real root cause when production breaks and it is unclear whether the application, the cloud or the CDN is at fault, then fixing it and adding the monitoring that keeps it from coming back. Case study: an HTTP 500 that only Googlebot saw.

### Security & Reliability

Investigating security incidents, reviewing infrastructure and access, and hardening production: secrets kept out of source code, and vulnerability and leaked-secret scanning (Trivy, Semgrep, Gitleaks) in CI, so risks are caught before they become incidents.

### Technical Leadership

Keeping a project technically on course: architecture direction and trade-off decisions, reviews that catch risk before release, mentoring, and leading the team through incidents — as Tech Lead on healthcare, tax and accounting, and enterprise web projects.

### Full-stack Web Development

Setting up and maintaining Next.js, React, Nuxt and Vue applications together with the API behind them, and resolving the framework, routing and i18n issues that slow a whole team down — from corporate websites to healthcare systems.
