About Tim

I am a Senior Atlassian Architect and Developer with 15+ years of experience designing, optimizing, and extending Jira and Confluence environments for enterprise clients. I specialize in Atlassian Cloud, Forge app development, workflow automation, and custom integrations that streamline processes and improve team efficiency.

I build scalable, secure, and maintainable solutions using Forge, React, TypeScript, Node.js, REST/GraphQL APIs, OAuth, and ScriptRunner (Groovy). My work ranges from custom UI components and workflow logic to full end‑to‑end business automation and cross‑system integrations.

I have led multiple Cloud and Data Center migrations, modernized legacy configurations, and implemented best‑practice architectures for organizations with 1,000+ users. I work independently, communicate clearly, and deliver clean, well‑documented solutions that are easy to maintain.

What I deliver:
Custom Atlassian Forge apps (UI, backend, storage, webhooks)
Jira/Confluence automation and workflow engineering
Integrations with Slack, GitLab, internal APIs, and more
Cloud and Data Center migrations
System architecture, performance optimization, and governance
ScriptRunner automation (Groovy)
CI/CD pipelines and version management for Atlassian apps

If your team needs a senior engineer who can design solutions, build them end‑to‑end, and improve your Atlassian ecosystem with modern Cloud technologies — I can help.

    Designed, built, and published ThreadFlow: Smart Slack Conversations, a Forge-based Jira Cloud app that synchronizes Jira issue comments with Slack thread replies in real time.

    Implemented two-way comment sync, Slack thread binding, and automatic Slack message updates to keep Jira the single source of truth while reducing context switching for engineering teams.

    Developed the app’s integration architecture (Forge triggers, webhooks, Slack API, comment mapping logic) and optimized it for reliability and low-latency updates.

    Worked with several short-term clients on targeted Jira/Confluence improvements (workflow cleanup, ScriptRunner automation, Cloud migration preparation).
