About Ahmed Yar
AI Agent & Chatbot Developer | Full-Stack Web/App | LangChain n8n
Karachi, Pakistan - 8:09 am local time
WHAT I DO:
- AI Chatbots & Agents — support bots, sales assistants, workflow agents, and web-scraping/data-extraction agents using LangChain, OpenAI Agents SDK, FastAPI, and RAG (retrieval-augmented generation) pipelines over your own data.
- Business Process Automation — connecting your CRM, email, Slack, spreadsheets, and internal tools into automated workflows so repetitive tasks run themselves, freeing up your team's time.
- Full-Stack Web & App Development — Next.js, React, Node.js, and NestJS front/back ends with clean REST and GraphQL APIs, built for production use, not throwaway demos.
- Cloud & DevOps — AWS-certified; serverless functions, scalable backend architecture, database integration (SQL/NoSQL), and reliable deployments on AWS and Firebase.
RECENT WORK:
- Video Studio Pro — AI video editing SaaS built on Next.js + Gemini and multiple generative AI tools. Real-time previews, credit management, and PDF/text processing, deployed on AWS.
- AI Web Scraping Agent — intelligent agent using FastAPI, SQLAlchemy, and the OpenAI Agents SDK, enabling context handoff between tasks, automated data extraction, and workflow management.
- Devedge Consulting — custom web apps and dashboards (Next.js, React, Node.js, AWS, Firebase), plus automation workflows that measurably improved client efficiency.
- Smart Parking System — Raspberry Pi + ESP32 + ANPR IoT system automating vehicle tracking, entry/exit logging, and billing for unregistered vehicles.
- AWS Cloud Solutions — serverless functions, backend services, and database integration for scalable web and IoT applications.
HOW I WORK:
1. Scope — I ask the questions that matter before writing a single line of code, so we agree on what "done" looks like.
2. Build — I share progress early instead of disappearing until "finished," so there are no surprises.
3. Deploy & document — every project ships with clear documentation and a working deployment, not just source files.
4. Support — I stay reachable after delivery for fixes and small iterations; I don't disappear after payment.
WHO I WORK BEST WITH:
Startups and small businesses who need a chatbot, an internal automation, or a full product built by one person who can own the whole stack — instead of coordinating three separate freelancers for frontend, backend, and AI.
QUICK ANSWERS:
- Can you build a chatbot for my website, WhatsApp, or Telegram? Yes — using LangChain/OpenAI Agents SDK with RAG over your own docs or data.
- Can you automate my business workflows? Yes — connecting CRMs, email, Slack, spreadsheets, and internal tools into automated pipelines.
- Do you build the full app, not just the AI part? Yes — frontend, backend, database, and deployment as one deliverable.
- Do you work with startups and small teams? Yes — that's most of my client base, and I scope work to fit tighter budgets and timelines.
- Are you AWS certified? Yes — AWS Developer Certification, so cloud deployment and architecture are core strengths, not an afterthought.
STACK: LangChain, OpenAI Agents SDK, FastAPI, Next.js, React, Node.js, NestJS, Python, AWS, Firebase, SQL/NoSQL, REST/GraphQL, SQLAlchemy, Git.
CERTIFICATIONS & EDUCATION:
- AWS Developer Certification (SMIT) — cloud development, deployment, and integration on Amazon Web Services.
- Automation Play x Mindstorm Engineering — Industry 4.0 IIoT bootcamp covering PLC, HMI, SCADA, Node-RED, and industrial AI/ML/cloud integration.
- B.Sc. (Hons.) Applied Physics, University of Karachi — 1st division, 3rd position.
- B.S. Computer Science, University of Karachi (in progress).
INDUSTRIES I'VE WORKED WITH:
SaaS & video/content tools, consulting & agency web platforms, IoT/hardware-integrated systems, and internal business tooling — so I'm comfortable whether your project is consumer-facing or an internal ops tool nobody outside your team will ever see.
WHAT MAKES ME DIFFERENT:
Most "AI automation" freelancers are frontend developers who added a chatbot API call. I came from embedded systems and applied physics before software — I've debugged hardware with an oscilloscope and a logic analyzer, not just a browser console. That systems-level thinking carries over: I design for edge cases, failure states, and what happens when your automation runs 10,000 times unattended, not just when it runs once in a demo.
TYPES OF PROJECTS I TAKE ON:
- Building a custom AI chatbot trained on your product docs, FAQs, or internal knowledge base.
- Automating a manual process your team repeats every day (lead intake, invoice processing, report generation, data entry between tools).
- Building a new web or mobile app from scratch, or adding features to an existing code
