Independent software developer | Xiang Peng (Penn)
Need software built, an existing project taken over, or a system fixed? I can handle it.
I work directly with businesses, teams, and individuals on software development, system upgrades, production troubleshooting, and ongoing maintenance. You deal with me from the first conversation through delivery and long-term support.
How I can help
You can bring me the project as it is
A new idea, an unfinished product, an inherited codebase, or a live system that keeps failing: I can start from the current state and move it forward.
Software development and maintenance
I can start with requirements and architecture, or work directly with your existing code, servers, and databases. I diagnose the current state, make the changes, and verify that the system works.
Custom Software Development
Web apps, mobile apps, desktop software, backend services, business systems, and internal tools.
Take Over Existing Projects
I can take over projects with missing documentation, unstable code, or no current maintainer.
Upgrade and Migrate Systems
Upgrade frameworks and platforms, move deployments, and migrate servers or databases.
API and Platform Integrations
Connect payments, devices, external platforms, APIs, and webhooks.
AI and Workflow Automation
Build AI agents, data and content workflows, and practical internal automation.
Long-Term Maintenance and Support
Troubleshoot production issues, maintain servers and databases, improve performance, and keep the system supported.
Technical analysis and project notes
I write about open-source project evaluation, production troubleshooting, upgrades, migrations, and system maintenance. These notes show how I assess a problem and decide what to do next.
