You will get a broken Zapier, Make, n8n, API, or webhook workflow diagnosed or repaired
Project details
Is a Zapier, Make, n8n, CRM, or custom webhook silently dropping fields, creating duplicates, or failing after an API change? I will reproduce the failure with a safe fixture, trace the exact payload, schema, authentication, timing, or retry boundary, and verify the result against agreed test cases.
Starter delivers a root-cause diagnosis and fix plan for one failing boundary. Standard repairs one workflow up to 12 steps and verifies 3 test cases. Advanced repairs up to 3 connected workflows and adds retry, idempotency, and error-path checks.
You can start with a redacted export and one sanitized failing run; production secrets are not required. Live writes or sends happen only in a sandbox, with test recipients, or after your explicit approval. You receive evidence, documented changes, and a portable export or rollback where applicable.

Frequently asked questions
About Dmitry
Full-Stack & Automation Engineer | APIs, Webhooks, n8n, Make, Zapier
Odessa, Ukraine - 8:35 pm local time
I also build and improve scalable web applications with React, Next.js, and TypeScript. My work includes SaaS products, dashboards, admin panels, authentication and role-based systems, API integrations, performance optimization, bug fixing, and unfinished feature delivery.
Relevant experience:
• tracing payload, schema, authentication, timing, and retry failures across integrations
• building multi-tenant products with typed API contracts and role-based access
• integrating REST and GraphQL APIs
• writing Playwright and Jest tests and setting up Sentry monitoring
• refactoring legacy code while preserving reliable delivery
What I can help with:
• Zapier, Make, n8n, API, and webhook diagnosis or repair
• React / Next.js development
• admin panels and internal tools
• authentication and role-based access
• API integration and full-stack MVP delivery
• performance optimization, bug fixing, and test coverage
Tech stack: React, Next.js, TypeScript, JavaScript, Node.js, NestJS, Supabase, PostgreSQL, GraphQL, Playwright, Jest, Sentry, n8n, Make, Zapier, APIs, and webhooks.
I focus on bounded scope, reproducible evidence, safe changes, and a maintainable handover.
Steps for completing your project
After purchasing the project, send requirements so Dmitry can start the project.
Delivery time starts when Dmitry receives requirements from you.
Dmitry works on your project following the steps below.
Revisions may occur after the delivery date.
Reproduce and scope
Inspect the redacted export and failing run, create a safe test fixture, and confirm the expected output and repair boundary.
Trace and repair
Isolate the failing payload, schema, timing, auth, or retry boundary. For repair packages, change only the approved workflow scope and preserve rollback.
