n8n Automation | AI Agent Developer | Python | FastAPI | System Design

Your systems grew faster than their architecture. Automations break and nobody can say why. Decisions about what to build versus what to buy get made blind, and the cost of a wrong call keeps climbing. That is the work I do. I design the architecture behind operational processes, audit what already runs, and build the systems that hold up as the business grows. Not quick fixes or template automations. Production systems with real logic, error handling, and long-term stability. ━━━━━━━━━━━━━━━━━━━━━━━ WHAT I DO ━━━━━━━━━━━━━━━━━━━━━━━ — Architecture & System Audit — → Map how your processes actually work, find the bottlenecks and failure points → Design data flows, system logic, and the build-vs-buy calls behind them → Deliver a clear architecture you can act on, not a slide deck — AI Systems & Agentic Workflows — → Structured AI that processes data and automates decisions, not chatbots → RAG and embeddings, document intelligence, multi-step agent orchestration → The hard part: drawing the line between what AI decides and what code enforces, with validation, fallback logic, and cost control — System Integration & Orchestration — → Connecting APIs, tools, and databases into one reliable flow → Data consistency, error recovery, and reliability at scale — Business & E-commerce Process Automation — → Order processing, fulfillment, inventory sync, CRM and reporting workflows → Replacing fragile manual work with systems that keep running ━━━━━━━━━━━━━━━━━━━━━━━ HOW I WORK ━━━━━━━━━━━━━━━━━━━━━━━ 1. Analyze — find the bottlenecks, manual work, and failure points 2. Design — architecture with clear data flows and system logic 3. Build — production workflows with error handling and monitoring 4. Deliver — a documented system your team can run and extend I don't just connect tools. I design systems that keep working as the business grows. ━━━━━━━━━━━━━━━━━━━━━━━ RESULTS ━━━━━━━━━━━━━━━━━━━━━━━ → Cut manual work by 60–80% across operations workflows → Dropped fulfillment time from minutes to seconds → Ended recurring errors in order processing and data handling → Built systems handling 100+ weekly operations with near-zero errors → Reverse-engineered sources with no APIs and held strict accuracy under load ━━━━━━━━━━━━━━━━━━━━━━━ TECH STACK (WHEN NEEDED) ━━━━━━━━━━━━━━━━━━━━━━━ AI: Claude, OpenAI, RAG, vector databases, agent orchestration Automation: n8n, APIs, webhooks Backend: Python, Node.js, PHP Data: PostgreSQL, Airtable, Qdrant Integration: Shopify, WooCommerce, HubSpot, Salesforce, Zendesk Infrastructure: Docker, VPS, self-hosted (Used only when the problem calls for it. The focus is the business problem, not the tool.) ━━━━━━━━━━━━━━━━━━━━━━━ GOOD FIT IF ━━━━━━━━━━━━━━━━━━━━━━━ ✓ Your systems don't work well together and nobody owns the full picture ✓ Your automations break or stop scaling ✓ You want AI inside real workflows, not a chatbot demo ✓ You need someone to audit the architecture before you build more Not a fit if you're looking for the cheapest or simplest solution. ━━━━━━━━━━━━━━━━━━━━━━━ LET'S TALK ━━━━━━━━━━━━━━━━━━━━━━━ Tell me where it hurts: → What breaks most often? → Which systems need to work together? → What decision are you stuck on — build or buy? I'll tell you what's worth fixing, what impact to expect, and the best way to approach it.
