How to hire an n8n automation expert?

Look for engineers who specialize in 'deterministic automation' and 'self-healing workflows' rather than just connecting APIs. My service includes a full architecture audit, custom n8n node development, and guaranteed error handling protocols to ensure 99.9% uptime.

What is an AI Workflow Architect?

An AI Workflow Architect doesn't just write prompts; they build the infrastructure (RAG, Vector DBs, n8n orchestrators) that makes AI agents reliable in production. I combine Next.js full-stack skills with advanced agent frameworks like LangGraph to build complete business systems.

Cost of building custom AI agents?

Professional AI agent development typically ranges from ₹75,000 to ₹5,00,000 depending on complexity (e.g., single-task bot vs. multi-agent orchestration). My pricing is value-based, focusing on the revenue generated or hours saved by the system.

Omni-Post AI to Sanity Portfolio Integration Architecture

Role: Technical Specification Scope: Omni-Post AI Automation Engine (Part 2) connection to amansuryavanshi.dev Portfolio Sanity CMS. Last Updated: April 2026

1. Overview & Architecture Flow

The Omni-Post AI Automation Engine operates in two phases. Part 1 acts as the Generative Engine, utilizing AI and Obsidian MCP context to write platform-specific drafts. Part 2 acts as the Distribution Engine, taking approved drafts from Notion and pushing them to multiple platforms, including the primary portfolio blog managed via Sanity CMS.

Data Lifecycle

Generation (Part 1): AI writes the blog draft containing SEO strategies ("Career Engineer" framework) and injects it into Notion. Properties and drafts are saved using the Notion API.
Staging: Notion acts as the source of truth and review gate. Once marked "Approved", Part 2 is triggered.
Extraction & Parsing (Part 2): The automation pulls the Notion payload. The Code - Parse Blog Content (Blog Parser V16) extracts Markdown, images, and custom SEO fields.
Transformation: The Code - Rebuild Blog Blocks with Image References script tokenizes Markdown and converts it into a Sanity Portable Text mutation structure.
Publishing: The formatted payload is sent to the Sanity API to create/update the post document.

2. Source Data: Notion Properties

Part 1 stores highly structured metadata directly in Notion alongside the raw markdown text.

Key SEO & Organization properties extracted:

property_shared_seo_title
property_shared_slug
property_shared_seo_description
property_shared_tags
property_shared_focus_keyword
property_shared_article_type
property_shared_quotable_snippet
property_shared_content_summary
property_shared_faq_json (AEO strategy)
property_shared_key_takeaways (AEO strategy)
property_internal_links
property_breadcrumb
property_cta_type & property_cta_text
property_series_part & property_pillar_post
property_primary_category & property_subcategory

3. Transformation: Omni-Post Part 2 Nodes

The connection logic resides in two essential Code Nodes in Part 2.

A. Blog Parser V16.0 (`Code - Parse Blog Content.js`)

Block Splitting: Splits the monolithic Markdown draft into distinct text and image blocks based on the <IMAGE_N> marker pattern.
Asset Attachment: Cross-references image markers with downloaded binaries (falling back to multiple sources) ensuring that images in the content body match the required assets.
Validation: Sanitizes fields and parses JSON structures for FAQs and Takeaways, outputting a consolidated JSON payload.

B. Portable Text Rebuilder V14.0 (`Code - Rebuild Blog Blocks with Image References.js`)

Sanity requires the strict "Portable Text" JSON specification instead of Markdown.

Tokenization: Parses headers (#, ##), lists (ordered, unordered), fenced code blocks, and inline formatting (**, __, *, _, ```).
UUID Generation: Generates unique _key identifiers for every block and inline text span as required by Sanity.
Image Mapping: Converts type: 'image' blocks into Sanity _type: 'image' blocks referencing the pre-uploaded asset IDs.
Sanity Payload Construction: Maps all SEO fields, constructs the body array, and shapes the final mutations payload for the Sanity API.

4. Destination: Sanity `post` Schema Mapping

The portfolio codebase (amansuryavanshi.dev/src/sanity/schemaTypes/postType.ts) defines the post document. Below is the precise mapping from the automation output to the Sanity schema.

Core Content (`content` group)

Notion / Omni-Post Field	Sanity Field (`post` schema)	Type
`title`	`title`	`string`
`slug`	`slug.current`	`slug`
`description` / `excerpt`	`excerpt`	`text`
`focusKeyword`	`focusKeyword`	`string`
`keywords` / `tags`	`tags[]`	`array` (label & slug)
Calculated	`publishedAt`	`datetime`
`blocks` (Markdown)	`body`	`blockContent`

Answer Engine Optimization (AEO) & SEO (`seo` group)

Optimized by the "Career Engineer" AI framework to maximize semantic visibility and feature snippets in platforms like Perplexity and ChatGPT.

Omni-Post Field	Sanity Field	Description
`seoTitle`	`seoTitle`	Optimized title for search engines.
`description`	`metaDescription`	Short meta description (max 160 chars).
`quotableSnippet`	`quotableSnippet`	Short, quotable answer designed for AI engine extraction.
`contentSummary`	`contentSummary`	2-3 sentence overview optimized for AI citation.
`focusKeyword`	`primaryKeyword`	Target primary search term.
`secondaryKeywords`	`secondaryKeywords`	LSI terms for semantic context.
`faqItems`	`faqItems`	Question/Answer pairs mapped to FAQ schema.
`keyTakeaways`	`keyTakeaways`	List of actionable bullet points.
`internalLinks`	`internal_links`	Semantic internal linking mapping.
`ctaType` / `ctaText`	`cta_type` / `cta_text`	Strategy-based CTA mapping.
Calculated	`canonicalUrl`	Crucial for Dev.to / Hashnode cross-posting (`https://amansuryavanshi.me/blogs/${slug}`).

Structural Metadata (`meta` group)

Omni-Post Field	Sanity Field	Note
`primaryCategory`	`primary_category`	Reference mapping.
`subcategory`	`subcategory`	String identifier.
`articleType`	`articleType`	Categorization for Schema.org (e.g., tutorial, guide).

5. Security & Operations

API Authorization: Uses a Sanity API Token configured as a credential inside n8n.
Image Pipeline Constraint: Sanity requires images to be uploaded first. The automation uploads images yielding an assetId, which is then referenced in the Portable Text mutation payload (Code - Rebuild Blog Blocks).
Idempotency: Drafts are merged into Sanity via create mutation, leveraging unique slugs. Cross-posted versions (Dev.to, Hashnode) utilize the generated Sanity canonicalUrl to avoid SEO cannibalization and maintain authority on amansuryavanshi.me.
