You will get an AI-powered data collection, extraction and normalization
Top Rated
Project details
You will get a production-ready AI data pipeline that collects, extracts, and normalizes data from any web sources into your target
schema – automatically, reliably, and at scale.
Most rule-based solutions break the moment a source changes its layout. Ours use LLM-based extraction that understands content semantically, not by rigid selectors. This makes the pipeline significantly more resilient to source changes and suitable for
production use.
What you get depending on your tier:
– Starter: a working proof of concept on up to 5 sources, structured output in JSON, CSV, or DB, ready in 1 week
– Standard: a full production pipeline on up to 20 sources with scheduled runs, health monitoring, and runbook
– Premium: up to 50 sources with a quality gate agent, admin dashboard, and full integration with your existing product
Every delivery includes source code, setup documentation, and a handoff session. We do not disappear after delivery.
We have built this in production: an AI event aggregation pipeline we delivered helped a B2B SaaS scale client onboarding from 1 to 5 per month at 95%+ data quality.

AI Developer Needed - Construction Document Parser & Data Extraction Tool
Refat did a great job hitting deadlines and keeping the development schedule on track. The product I'm showing off to potential customers is way above expectations and I would highly recommend his team for future work.

Lead Backend Developer - AI Information Platform (RAG/Vector Database)
Refat is very good developer with deep expertise on AI and how to apply it. Together we did a great project that really moved the business forward. He took the liberty to explore and suggest alternative solutions to what I was asking, providing value to our business. This goal-oriented approach is much better than just delivering us what we are asking for. This way, his expertise guides us in creating useful projects for the business in the best way possible. The whole process of working with Refat is just great and I would recommend his services to everyone!

Job Success
Kyiv, Ukraine - 1:48 am local time
Our AI engineering team builds production systems, not research demos. We design agent architectures, RAG pipelines, and AI workflows using TypeScript (Mastra, Vercel AI SDK) and Python (LangGraph, Agno, Pydantic AI, LangChain). We work with Claude, OpenAI ChatGPT models, Gemini, and open-weight models (including GLM, Kimi, DeepSeek and many more), choosing based on task fit and cost constraints. We practice eval-driven development. Automated eval pipelines, LLM-as-judge scoring, quality gates, all of that runs before anything ships to production. We build MCP integrations and custom Agent Skills, implement structured outputs with guardrails, set up agent observability with tracing, and design context architectures so models get the right information at every step. We have delivered domain-specific AI assistants with RAG and ongoing eval monitoring, agentic tools with multi-step reasoning and tool use, legal document processing at 95% accuracy, AI data aggregation with automated validation, voice agent systems, and generative UI products.
Our full-stack team supports AI products with solid web infrastructure: React, Next.js, Vue.js, TypeScript, Node.js, GraphQL, and REST APIs. We deploy on AWS, GCP, and Vercel, and work with PostgreSQL, Redis, and vector stores (Pinecone, Qdrant, pgvector). For mobile we use React Native and Flutter.
Delivered results: RAG-powered support bot reduced resolution time by 70% and lifted NPS by 20%. AI event aggregation pipeline scaled B2B SaaS onboarding from 1 to 5 clients per month at 95% data quality. LLM document system cut legal research from days to hours. AI landing page builder matched agency-level output with zero designer involvement. First-year ROI across AI projects averages 3.2x.
We have built AI systems for LegalTech (tax advisory, contract analysis), Healthcare (medication search with voice agents), Transportation (fleet management, real-time optimization), E-Commerce (content generation), SaaS platforms with AI-native features, and B2B products with intelligent data pipelines.
Our clients are startups embedding AI into their product, and companies replacing manual workflows with intelligent automation. We cover the full cycle: discovery, architecture, development, eval pipeline setup, deployment, and ongoing optimization.
Steps for completing your project
After purchasing the project, send requirements so Refat can start the project.
Delivery time starts when Refat receives requirements from you.
Refat works on your project following the steps below.
Revisions may occur after the delivery date.
Discovery & Scoping
We review your sources, target schema, and integration requirements. We flag any blockers (login-protected sources, access restrictions) and confirm the final scope before work begins.
Pipeline Development
We configure data collectors, build the LLM-based extraction and normalization logic, implement deduplication, and set up structured output delivery to your target format or database.
