You will get Production bug diagnosis and fixes for React, Vue, or Node.js applications
Project details
I will investigate and fix a specific bug in your existing React, Vue, TypeScript, or Node.js web application.
I start by reproducing the issue and tracing the affected flow to identify the actual root cause. Then I implement a focused fix while preserving the existing architecture and avoiding unnecessary rewrites.
This service can cover frontend bugs, backend issues, broken API integrations, state or async problems, browser compatibility issues, and other web application defects.
Each order covers one clearly defined bug or closely related broken flow. If the investigation shows that the issue requires a larger refactor, multiple unrelated fixes, or work outside the selected package, I will explain the findings and agree on the additional scope before proceeding.
You will receive:
• Root-cause investigation
• Production-ready fix
• Focused code changes
• Verification of the affected flow
• Short summary of what caused the issue and what was changed

Frequently asked questions
About Bohdan
Full-Stack Developer | React, Vue, Node.js, TypeScript
Warsaw, Poland - 10:11 pm local time
I help clients build new product features, fix difficult production issues, improve existing web applications, and integrate frontend and backend systems without unnecessary rewrites.
I can help with:
• Full-stack feature development
• React / Vue / TypeScript frontend work
• Node.js / NestJS backend development
• REST APIs and third-party integrations
• Production bug investigation and fixing
• WebSockets, realtime systems and WebRTC
• SaaS product development
I’m also the founder and technical owner of StreamAssist, an interactive realtime platform for creators. I work across its frontend, backend, realtime architecture, WebRTC/mediasoup, Twitch integrations, interactive features and production releases.
I’m comfortable joining an existing codebase, understanding how it works, finding the real cause of a problem and delivering a focused solution without breaking unrelated functionality.
If you have a broken production flow, a feature that needs to be shipped, or a realtime/web application that needs engineering help, feel free to send me the details.
