My Story

Building AI systems that run businesses on autopilot.

Sameer Ansari Profile Photo

Hey, I'm Sameer — a Senior Backend Engineer who got pulled into the world of AI automation. What started as core backend engineering has turned into building full-scale AI agent systems that run real businesses.

I help businesses replace manual, repetitive work with automated AI pipelines. From capturing and qualifying incoming leads to drafting personalized follow-up sequences, everything is designed to run hands-off.

I don't just prompt-engineer chatbots that sit on a website. I build production-grade, custom-coded automation systems end-to-end, with absolute care, stability, and attention to database performance.

What I Actually Do

Workflow Automation

End-to-end orchestration using n8n, custom webhooks, and REST API integrations to sync data flawlessly.

AI Agents

LLM-powered autonomous agents that draft replies, score prospects, and perform operations based on logic.

Backend & CRM Systems

Scalable Node.js architectures, Supabase/PostgreSQL database design, and high-performance data pipelines.

Featured Case Study

AI Real Estate CRM Automation

Live in production for Maikos Real Estate. A fully hands-off pipeline that qualifies and nurtures inbound leads.

The Problem

Leads arrived with incomplete budget, timeline, or location info. Manual screening took hours, wasting time on low-intent inquiries while hot prospects sat cold.

What I Built

A custom n8n agent system that listens to Supabase logs. When a lead is captured, it scores client intent (HOT/WARM/COLD) using GPT-4. It immediately triggers a tailored response requesting missing criteria via Gmail API and schedules follow-ups.

The Result

Zero manual qualification. Instant response times, improved lead score visibility, and automatic CRM tracking with no manual data entry.

How I Work

A transparent step-by-step approach built to transition business operations from manual entry to automated efficiency.

01

Discovery Call

We discuss your current bottlenecks, manual tasks, and operations to understand what workflows can be automated.

02

Map Your Workflow

I map out the current process and map it to a digital blueprint, showing where AI agents and APIs fit.

03

Build & Automate

I build the integrations in n8n, write custom Node.js backend connectors, query LLMs, and test extensively.

04

Deploy & Support

Go live in production. I monitor performance, handle edge cases, and keep everything running smoothly.
