Web scraping
Unfortunately, my experience working with this freelancer was disappointing.
We initially agreed on a fixed price for the project, and I later opened an hourly contract under the assumption that the number of logged hours would match the agreed fixed amount. However, the freelancer logged significantly more hours than what was discussed, effectively exceeding the original agreement.

About Shahidul Ahad
Python Developer | FastAPI, Django, Web Scraping & AI Automation
100%
Job Success
Rangpur, Bangladesh - 10:17 pm local time
⭐ 889+ hours billed on Upwork across 19 successful projects
⭐ Backend systems handling millions of records with PostgreSQL, Redis & Docker
⭐ Data scraping for JavaScript-heavy sites and dynamic content
⭐ AI-powered automation with OpenAI, Claude, LangChain & LangGraph
⭐ Clean, tested, production-ready code
🔹 What I build for clients:
- High-performance REST & async APIs with FastAPI, Django, and Flask
- Web scraping & data extraction with Selenium, Scrapy, Playwright, BeautifulSoup
- Automation bots for data collection, workflow, messaging, and desktop tasks
- AI agents & LLM workflows with LangChain, LangGraph, OpenAI, and Claude
- ETL pipelines with PostgreSQL, MySQL, Redis, and Celery
- Dockerized deployments with CI/CD on AWS, Render, and DigitalOcean
- Secure authentication with JWT, OAuth2, and role-based access control
🔹 Python Backend Development
I design backend architectures that handle real workloads — microservices with FastAPI and Django, async PostgreSQL queries, Celery + Redis for background jobs, and RabbitMQ for distributed tasks. I build APIs that integrate cleanly with third-party services (Stripe, Twilio, OpenAI, Google APIs) and deploy them with Docker and Nginx for fault-tolerant production environments.
🔹 Web Scraping & Data Extraction
I build Python scrapers that handle complex sites — dynamic React/Vue/Angular content, authenticated sessions, and public REST/GraphQL APIs. I work with both browser automation (Selenium, Playwright) and pure HTTP scrapers (Scrapy, Requests) depending on what the target source needs. Data is cleaned, validated, and delivered in CSV, JSON, Excel, or directly to your database. I only work with public data or sources you have authorization to access.
🔹 AI Automation & LLM Integration
I build production-grade AI systems using LangChain, LangGraph, and Langfuse — from simple LLM workflows to multi-agent systems with tool use, memory, and state management. I integrate OpenAI, Claude, and other LLM APIs for text parsing, data enrichment, classification, summarization, and intelligent agents. I build RAG systems with vector databases (Pinecone, Chroma, pgvector), prompt pipelines, and AI-powered ETL flows that turn unstructured data into structured business insights. With Langfuse, I add full observability — tracing, evaluation, and cost monitoring for every LLM call in production.
🔹 Selected Projects
- AI-Powered Job Data Pipeline — Async FastAPI ETL ingesting XML feeds, AI enrichment, syncing to external APIs via Docker
- Script Marketplace Platform — FastAPI + Docker SDK platform running isolated bot containers with task scheduling and live monitoring
- Browser Automation Desktop App — Tkinter-based tool with advanced Selenium logic, session handling, and modular UI
- Multi-Tenant E-Commerce ERP — Django + gRPC + Stripe + PostgreSQL with real-time order tracking
- Financial Intelligence Dashboard — Python Dash analytics platform for structured financial data
- PyQt5 WhatsApp Automation — Desktop messaging automation with a polished GUI
- HLS to RTSP Conversion API — FastAPI service for live video stream conversion
🔹 Frontend (when needed)
I focus on Python backend, but I can build clean, functional UIs in React, HTML, CSS, and JavaScript when a project needs an integrated frontend — so you don't have to hire two people for one workflow.
🔹 How I work
✓ Agile development with Git, GitHub, and Jira
✓ Clear daily communication and status updates
✓ Clean, modular code with proper testing and documentation
✓ Honest timelines — I tell you what's realistic, not what you want to hear
✓ Post-delivery support and revisions included

Steps for completing your project
After purchasing the project, send requirements so Shahidul Ahad can start the project.
Delivery time starts when Shahidul Ahad receives requirements from you.
Shahidul Ahad works on your project following the steps below.
Revisions may occur after the delivery date.
Requirement analysis & architecture planning
I review your requirements, recommend the best framework and database for your use case, and share a clear architecture plan covering endpoints, data models, and authentication before any code is written.
Database & API development
I design the database schema with proper migrations, then build the API with clean, modular code — proper separation of routers, services, and models for maintainability.
