DeAndre Harris

Senior support engineer with 10+ years of experience solving challenging customer problems in SaaS, developer tools, and infrastructure.

I work well with trust and broad context: debugging issues across APIs, databases, DNS, networking, CI pipelines, and customer environments; digging into code when needed; communicating clearly with customers; and turning repeated difficulties into better product behavior, documentation, and support systems.

I identify the work that needs to be done, shape it, and carry it through. Recent examples include completing an Intercom-to-Plain migration and building a Go administration system that runs as both a CLI and MCP server, redacts PII by default, and requires confirmation before destructive actions.

Areas of Depth

Customer debugging and escalation

I’ve spent most of my career handling technical issues across hosted and self-managed environments through email, chat, phone, and video. I start by reproducing the problem and isolating the failure point, whether the issue lives in product behavior, customer configuration, infrastructure, or process. The work ranges from implementation problems and API behavior to networking, configuration, and incident response.

Product feedback and cross-functional work

I work closely with engineering and product to turn recurring tickets into fixes and better support workflows. That’s been part of my job in all roles. One public example is this GitLab merge request, which came out of a customer issue pattern.

Documentation and self-serve support

I’ve written and improved technical documentation, troubleshooting guides, and internal support systems to cut repeat questions and help customers solve more on their own.

Support tooling and operational leverage

I build internal tools when they save the team time, make investigations easier to repeat, or put guardrails around sensitive work. That includes automation and workflow improvements, MCP-based documentation retrieval, QA and escalation workflows, reporting, and day-to-day administration. The AI-assisted parts focus on PII protection, confirmation before destructive actions, and human review.
