Hiring n8n specialist — PostgreSQL + email automation project

Jobs
43

Hi John — this is a clean small-scope n8n build. I’d approach it as two weekly workflows plus shared reusable pieces: one Postgres query/normalization layer, one formatter for the statement rows, and one Azure Communication Services send step with dry-run/test recipients before enabling the schedule.

For a fixed first milestone I’d build one weekly statement path end-to-end first: SQL query → grouping/pairing → formatted email preview → send/log row → error alert. Once that is validated, the second workflow and month-end variants are mostly controlled reuse rather than a separate rebuild.

I work with n8n Code nodes, SQL/Postgres, email workflows, and handoff docs. Happy to help with this as a fixed-price small project.

Hi ignatius,

This project is squarely in my wheelhouse — n8n self-hosted, PostgreSQL queries inside Code nodes, and formatted outbound email via third-party mail services.

Quick match on your requirements:

  • Write complex JS in n8n Code nodes daily — grouping, pairing, and conditional formatting logic is straightforward
  • PostgreSQL inside n8n workflows: parameterised queries, joins, aggregations — done this for production B2B client systems
  • Sent formatted email via Azure, SendGrid, and SMTP from n8n with dynamic recipient lists and copy/BCC logic

The weekly workflow you described (query → group into pairs → send formatted statements to two parties + CC) is a clear scope. Month-end summary variants are a natural extension once the base query logic is solid.

5–9 hours is a reasonable estimate for the two workflows plus the month-end variants. Happy to share examples of similar n8n + PostgreSQL work.

Hi Ignatius — this is a clean fixed-scope n8n/PostgreSQL build.

I would scope the first pass around the statement-generation contract, not a broad rebuild:

  1. confirm the session schema, recipient tables, and exact pairing/grouping rules
  2. write the Postgres queries for the weekly pair statements and recipient summaries
  3. shape the rows in Code nodes into stable statement payloads
  4. send through the existing Azure Communication Services path with cc rules per statement type
  5. add idempotency so a weekly or month-end run cannot resend the same statement twice
  6. log each attempted send with status, recipient, period, statement type, and provider response

For a 5-9 hour build, I would quote this as a fixed first milestone around $900-$1,500 depending on how clean the schema and email templates are. I can work async from the schema, one or two sample records, the desired email layout, and a safe test recipient list. Credentials can stay in your own n8n/Azure environment.

A good deliverable would be: two weekly workflows, month-end variants or parameterized date windows, test payloads, and a short handoff note showing the query assumptions and rerun/retry behavior.

Hi,

This is a strong fit for a fixed-scope n8n build because the stack and deliverables are already defined: self-hosted n8n, PostgreSQL, Azure Communication Services, and two weekly email workflows.

I would keep the first pass disciplined:

  1. confirm the PostgreSQL grouping rules and sample rows,
  2. build each workflow in dry-run mode first,
  3. generate test email payloads before any live recipients,
  4. add basic logging so missed/failed weekly sends are visible,
  5. deliver a short handoff doc covering queries, formatting rules, test cases, and where to adjust recipients.

I can work async from the current workflow export, schema/sample rows, and expected email examples. I would use test recipients first, not live production sends.

Sample diagnostic/handoff artifact: Automation Failure Rescue sample diagnostic pack · GitHub

If that matches what you need, send the schema/sample rows and expected statement format and I can confirm fixed scope.

Hey Ignatius,

This is squarely in my lane — self-hosted n8n + PostgreSQL + formatted email delivery is the exact stack I work in daily.

For the two weekly workflows + month-end variants, here’s how I’d approach it:

  1. PostgreSQL queries via n8n’s Postgres node — grouping/pairing logic handled in SQL (not in Code nodes) so it stays readable and maintainable by your team after handoff.
  2. Formatted email via Azure Communication Services — HTML templates with dynamic fields, proper error handling so a failed send doesn’t silently skip a recipient.
  3. Month-end variants as parameterized sub-workflows that share the core logic with the weekly versions — so future changes only need to happen in one place.

What you’d also get that most 5-9 hour quotes skip:

  • Idempotency check so a workflow re-run doesn’t send duplicate statements
  • Error notification workflow — if a send fails, you know immediately instead of discovering it next week
  • Written handover doc explaining the SQL queries and workflow logic

I’d quote this at $350 fixed, inclusive of the handover doc. Happy to scope tighter after a 15-minute look at your database schema.

Hi — this is squarely in my lane. Self-hosted n8n + PostgreSQL + formatted email delivery is the exact stack I work in daily.

For weekly workflows + month-end variants: PostgreSQL queries via n8n’s Postgres node — grouping/pairing logic in SQL or Code nodes, formatted HTML email output via n8n’s Email node.

I’d start with one of the weekly reports as a paid first slice: define the query, expected output format, and one test dataset. Once that runs cleanly, add the remaining variants.

Available immediately.

Hi Ignatius,

This scope is clear and I’d approach it as two small, testable workflows rather than one large automation.

For the first pass I would build:

  • PostgreSQL query for the required weekly records
  • grouping logic in an n8n Code node
  • formatted email body templates for each recipient type
  • Azure Communication Services send step
  • dry-run/test mode with sample recipients before live sends
  • simple run log so failures are easy to trace

The month-end summary can reuse the same query/template structure after the weekly version is verified.

I can work async and start with a small fixed-scope first milestone if you can share the current table shape and one example of the expected email output.

Best,
Tim

Hi ignatius,

This is a good small fixed-price project. I can help build the two weekly n8n workflows plus the month-end summary against your existing PostgreSQL data and Azure Communication Services email setup.

How I would approach it:

  • inspect the existing session-record schema and current ingestion workflow,
  • write the Postgres queries for pair grouping and recipient grouping,
  • format the email payloads cleanly inside n8n,
  • add logging/error handling so failed sends or missing records are visible,
  • create a dry-run/test mode before enabling the weekly schedule,
  • document the queries, schedule, assumptions and how to adjust recipients/copy rules.

For the scope described, I would quote 550 EUR fixed if the database schema and email credentials are already working, with a 1-2 day delivery window after access to a staging/sandbox setup or sample schema. First milestone/deposit before implementation, then final handoff after test evidence.

Best,
Carlos Silveira

Hi @Ignatius,

Your requirement is quite straightforward and aligns well with the type of workflow automation projects we regularly deliver.

From my understanding, the work involves building four automated reporting workflows on top of your existing infrastructure:

• Weekly paired-record statement workflow with automated email distribution to two parties and a copied stakeholder.
• Weekly grouped-recipient statement workflow with automated distribution to external recipients and copied stakeholders.
• Month-end summary versions of both workflows.

Our team has extensive experience working with n8n, PostgreSQL, JavaScript Code nodes, scheduled automations, data transformation logic, and email-based reporting systems.

Relevant experience includes:

• Building scheduled n8n workflows that query PostgreSQL databases, aggregate records, apply custom business rules, and generate automated reports.
• Developing JavaScript-based processing logic within n8n Code nodes for grouping, filtering, summarization, and custom formatting.
• Implementing automated email delivery workflows with dynamic recipients, CC logic, templated content, and conditional routing.
• Creating recurring operational and financial reporting systems with weekly and month-end summary generation.

Since your data ingestion workflow, PostgreSQL database, self-hosted n8n instance, and Azure Communication Services integration are already in place, the implementation should be efficient and focused primarily on query design, grouping logic, email formatting, and workflow orchestration.

You can learn more about our capabilities at www.leotechnosoft.net

If you’d like to discuss the requirements further or share sample database structures and email formats, feel free to reach me directly at smith.j@leotechnosoft.net.

I’d be happy to review the details and provide a fixed-price estimate.

Hi @ignatius — this project is close to the kind of small, testable workflow work I’m focused on.

I can help with the PostgreSQL queries, n8n Code node transforms, grouping logic, formatted weekly/month-end email statements, and a clean handoff/export.

Relevant proof/examples:

Suggested first step: I can do a small paid first slice: inspect the existing schema/sample records, draft the two SQL grouping queries, and sketch the n8n workflow shape before building the final JSON. For the full 5–9 hour scope, I can work fixed-price once the sample schema and statement format are clear.

This is small enough to scope cleanly.

I would build it as two weekly workflows plus month-end variants using:

  • parameterized Postgres queries for each statement type
  • Code nodes for grouping/pairing records and formatting statement payloads
  • deterministic email templates with test recipients first
  • run log table or audit rows for sent/failed/skipped statements
  • retry/error path for Azure Communication Services failures
  • dry-run mode so you can inspect generated recipient groups before sending

Estimated shape: 1 short diagnostic pass to confirm table structure and statement rules, then 5-9 hours for implementation/testing if the current ingestion data is clean.

I can take this as a fixed paid slice once I see the relevant table schema, sample rows, and the desired email format.
