Agentic Automation and a RAG system
- This project involved extraction of intelligence data to support report writing for a company that provides geopolitical, global, commercial intelligence. The data have been gathered from a number of resources (interview transcripts, online data, internal documents), and then a knowledge base has been build from it. This was the basis of a complex RAG system, that was evaluated against a golden dataset. Agents have been used to find out the contradicting intelligence, the statements supporting each other, and to store back the generated knowledge.
Used: Python, RAG, LangGraph, LangChain, deepeval, MCP

Himanshu N.
Last position:
Principal (Data Scientist/Data Engineer/Gen AI Engineer) at Marktguru Deutschland GmbH
Architected an agentic, real-time offer orchestration engine where specialized agents (retrieval, pricing/optimization, and policy/guardrails) coordinate to personalise promotions across customer touchpoints using RAG with FAISS over Delta Lake and low-latency Databricks Model Serving. Collaborated with product managers and commercial stakeholders to shape the roadmap and evaluate emerging agent patterns for production.
Designed an agent-based data quality service that orchestrates schema detection, entity normalization, and validator/exception-handling agents to clean multi-retailer SKU feeds at scale. Wrapped model calls in PySpark UDFs for distributed inference, automated via Databricks Workflows and CI/CD.
Developed a multimodal, agentic extraction pipeline where vision, parsing, and compliance agents collaborate to derive brand, packaging, and volume from scanned images using Claude 3 Sonnet with Swin Transformer encoders. Orchestrated via Azure Event Hub with outputs persisted to Delta Lake.
Implemented a GS1 taxonomy classification service built around cooperating agents for inference, drift monitoring, and auto-retraining governance using Falcon 180B (LoRA-tuned) with a batch pipeline on Databricks.
Created a hybrid agent workflow where a retrieval agent surfaces candidate matches via embeddings and a reasoning/verification agent (Mixtral 8x7B) adjudicates receipt-to-SKU alignment, integrated into a streaming Databricks pipeline.
Built a multimodal attribute inference pipeline structured as cooperating vision-language, rules/consistency, and compliance agents to fill NutriScore, nutrition fields, and packaging types from names and images using LLaMA 3-8B with CLIP embeddings.
Developed a GenAI-powered orchestration system that ingests recipes from multiple websites, parses ingredients through structured extraction agents, and dynamically links them to real-time retailer offers via tagging, semantic reasoning, and business-rule agents.

About the technology
What it is
A recommender system selects and ranks items that may interest a user, such as products, films, articles, jobs or music. It combines behavioral signals, item information and context to create personalized feeds, search results or next-best-action suggestions. The term recommendation engine is often used for the same type of solution.
What it builds
Recommender systems support discovery and decision-making across digital products. Typical deliverables include:
- Personalized homepages, feeds and product carousels
- Related-item, cross-sell and upsell recommendations
- Content, media and learning suggestions
- Ranking for search, marketplaces and advertising
- Real-time next-best-action and notification logic
Methods and tooling
Specialists work with collaborative filtering, content-based models and hybrid approaches. They may use matrix factorization, embeddings, gradient-boosted ranking or deep learning, depending on the data and latency needs. Python, SQL, scikit-learn, PyTorch, TensorFlow, Spark and feature stores commonly support experimentation and production delivery.
When expertise matters
Companies bring in freelance expertise when personalization is central to growth, retention or product quality but internal teams lack focused capacity. Signs include weak discovery, sparse feedback data, changing catalogs or a model that works in testing but fails in production. In Munich, specialists may support local product, retail, media and mobility teams on-site, remotely or in a hybrid setup.
Delivery concerns
A reliable system needs more than a predictive model. Professionals define events and labels, establish offline and online evaluation, manage cold-start cases and monitor drift, latency and recommendation diversity. They also connect model outputs to APIs, data pipelines and business rules while protecting personal data and keeping explanations understandable.
Choosing a specialist
Strong professionals can explain why a ranking approach fits the product, data and commercial goal. Look for experience with experimentation, feedback loops, recommender-system metrics and production monitoring, not only model training. A good specialist also challenges tracking assumptions, documents trade-offs and works clearly with product, data and software teams.
Frequently asked questions
Everything clients usually want to know about Recommender System, in one place.
A recommender system helps users discover relevant products, media, articles, services or other items. Companies use recommendation engines in feeds, search, marketplaces, streaming interfaces, advertising and next-best-action workflows.
A recommender system ranks items from behavioral, content and contextual signals, while search usually responds to an explicit query. Manual rules are easier to control but often adapt less well to changing interests; many products combine all three approaches.
A strong recommender system specialist should understand data modeling, event tracking, experimentation, APIs and production monitoring. Knowledge of machine learning, SQL, cloud data platforms and privacy-aware product design is also valuable.
The right level depends on scope, data quality and delivery risk. A recommendation engine for a focused catalog may need a simpler approach, while real-time ranking across several surfaces calls for experience with feedback loops, cold starts, evaluation and operations.
Yes. Recommender systems can be delivered remotely when data access, environments and decision owners are clearly organized. Munich-based companies should agree early on collaboration hours, documentation standards and whether German-language communication is needed.
A recommender system should be assessed with offline metrics and controlled product experiments, not model accuracy alone. Review relevance, coverage, diversity, freshness, business outcomes, latency and performance for new users and new items.
A recommendation engine can use views, clicks, purchases, ratings, searches, item attributes and session context. The specialist should check event quality, consent, label definitions and bias before choosing a model, because more data does not fix unreliable tracking.
Collaborative filtering is useful when many users interact with a broad set of items and those interactions reveal meaningful patterns. It can struggle with new users, new items and sparse catalogs, so content-based or hybrid methods are often added to improve coverage.
