You will get one business workflow automated with APIs, webhooks, and custom code
Project details
I build reliable custom workflow automations that connect business systems through APIs, webhooks, databases, and backend code.
This service is ideal when your team manually moves data between applications, repeats the same operational steps, follows up through spreadsheets or inboxes, or depends on fragile handoffs between systems.
I can automate workflows such as lead capture, CRM updates, scheduling, notifications, approvals, data synchronization, payment-status updates, recurring reports, and background processing.
I do more than make the happy path work. I design for invalid data, duplicate events, API failures, rate limits, retries, permissions, logging, and human review where required.
Each order covers one primary workflow with clearly defined triggers, actions, systems, and business rules. This offer uses APIs, webhooks, databases, and custom code. Third-party subscriptions, unsupported systems without usable APIs, and unrelated workflows are not included unless separately scoped.

About Ayaz
Senior Full-Stack AI Engineer | RAG, Agents, Automations & SaaS
Karachi Goth, Pakistan - 9:20 am local time
I help companies turn unfinished products, fragile prototypes, and disconnected workflows into reliable software that can actually be used in production.
I’m a senior full-stack engineer with 8+ years of experience, so I can work across the whole system instead of stopping when the project moves from frontend to backend, APIs, databases, integrations, or AI.
I can help you:
• Finish or rescue an existing SaaS product
• Turn an MVP or AI prototype into production-ready software
• Build RAG systems, AI agents, document assistants, and AI-powered products
• Add AI to an existing application without rebuilding everything
• Build internal tools, dashboards, portals, and workflow systems
• Fix or extend React, Next.js, Vue, Node.js, or Python applications
• Replace fragile automations when the workflow needs real custom engineering
Selected work
HR SaaS Platform
Built and helped lead the technical direction of a self-service HR platform for a German company, replacing a staff-heavy process with a customer-facing product that let HR teams create and launch recruitment campaigns themselves. The platform became a core part of the company’s offering, supported customer retention and renewals, and the business quickly grew to around $1M in monthly recurring revenue.
Darvesh AI — Custom RAG Platform
Built a full-stack RAG application over roughly 6,000 source documents using a custom Python retrieval engine. The platform delivers grounded answers with inline citations, exact source passages, full articles, conversational memory, chat history, and controlled sharing. In my testing for this use case, it delivered faster and more relevant answers than the Google Vertex AI and Morphik implementations I tested.
What you get
You don’t need one freelancer for the frontend, another for the backend, another for AI, and someone else for automations.
I can work across the complete system:
Frontend: React, Next.js, Vue, JavaScript, TypeScript
Backend: Node.js, Python, REST APIs, webhooks
AI: RAG, LLM applications, AI agents, custom retrieval systems, LangGraph, vector databases
Data: Firebase, relational databases, authentication, structured data systems
Automation: n8n, Make, Zapier, APIs and custom integrations
The goal is simple: build software that works reliably for your users and your business, not just something that looks impressive in a demo.
If you already have something built, send me what you have and where you’re stuck.
If you’re starting from scratch, tell me what the product needs to accomplish.
Steps for completing your project
After purchasing the project, send requirements so Ayaz can start the project.
Delivery time starts when Ayaz receives requirements from you.
Ayaz works on your project following the steps below.
Revisions may occur after the delivery date.
Review the workflow and confirm scope
I review the current process, desired outcome, systems involved, business rules, exceptions, access requirements, and acceptance criteria before development begins.
Design the automation architecture
I define the triggers, actions, API calls, webhooks, data flow, validation, database state, permissions, and error-handling approach.
