Questions clients ask

Answers

Can you build production n8n workflows?

Yes. I build n8n workflows with explicit state, error-handling subworkflows, retries, and dead-letter queues, so failures are caught and can be replayed rather than lost. Examples include a PostgreSQL budget state machine, the Autonomous AI Email Agent, and cloud cost and compliance workflows.

Can you build n8n AI agents?

Yes. I've built n8n agents with Gmail API ingestion, persistent thread memory, and Groq inference, plus AI steps using OpenAI, Gemini, and Langflow for screening, drafting, scoring, and assessments.

Can you integrate n8n with APIs?

Yes. That includes Gmail, Google Calendar, Google Sheets, Slack, ClickUp, Airtable, HubSpot, AWS, and custom REST APIs or webhooks, with authentication and rate-limit handling.

Can you connect n8n to PostgreSQL?

Yes. I use PostgreSQL with n8n for workflow state, audit logs, and dead-letter queues. The profitability guardrail project tracks budget states in PostgreSQL and isolates malformed payloads in a DLQ table.

Can you add retry and error handling?

Yes. Error Trigger subworkflows, jittered exponential backoff for rate-limited APIs, circuit breakers after repeated failures, and a dead-letter queue with alerts for anything that still fails.

Can you self-host n8n?

Yes. I set up self-hosted n8n on Docker or a VPS, which gives you control over the infrastructure, how workflows execute, and how the instance scales. The Autonomous AI Email Agent runs on self-hosted n8n exposed through a Cloudflare Tunnel.

Can you test AI agents?

Yes. I test whether an agent keeps context across turns, answers from the intended source, returns output in the expected structure, handles failed tool calls, and escalates when it should.

Can you perform API testing?

Yes. Authentication, authorization, status codes, payload validation, state transitions, business rules, and API/UI mismatches, with every defect documented as a reproducible request and response.

Can you test multi-tenant SaaS?

Yes. I led QA on PharmaConnect, a multi-tenant B2B pharmaceutical distribution platform, covering 20 end-to-end journeys across 6 user roles, with 80+ defects documented with API-level evidence and 11 critical P1 findings identified during enterprise QA and security testing. Across all QA engagements I have identified and documented 678+ defects.

Can you test authentication and authorization?

Yes. Session and token lifecycle, deactivated and changed accounts, role permissions at the API level, and cross-tenant access, backed by an RBAC permission matrix.

Can you perform business-logic testing?

Yes. Pricing, promotions, checkout, invoicing, payment reconciliation, and progress or reward systems, tested through the API under repeated requests, timeouts, and out-of-order steps.

Can you provide pre-launch QA?

Yes. A typical pre-launch package includes 20 exploratory journeys, API-level investigation, authentication and authorization checks, multi-tenant isolation tests, business-logic testing, a defect matrix, and a final QA report.

Do you work remotely with US and international teams?

Yes. I'm based in Karachi, Pakistan, and work remotely with international clients, with working hours that overlap US Eastern and Pacific business hours.

Do I need to provide my own API keys?

Yes. For LLMs and third-party services you provide your own accounts and keys, so usage costs and ownership stay with you. Credentials stay in your accounts.

How are projects delivered?

Every automation delivery includes documentation and a Loom video walkthrough. QA engagements end with a defect matrix, reproduction evidence, and a findings report.

Can you name the clients you've worked with?

Only where I have permission. Confidential client details, internal URLs, data, and payloads are never published.
