The Learni story
Founded by engineers and learning experts, Learni's mission is to make high-impact tech training accessible to teams everywhere. We work remotely with organizations across the US and Canada, in your time zone, to help teams upskill fast.
Don't let this gap widen
Why this program matters
Without this upskilling, your team accumulates a technological gap that translates directly into productivity loss.
Organizations that don't train their talents on key topics see their competitiveness drop.
Every quarter without training is a gap widening with competitors who invest.
The cost of inaction quickly exceeds that of well-targeted training.
Program
Module 1Hybrid Search Fundamentals: BM25 and Vector Embeddings (Elasticsearch, FAISS)
Dive into the advanced mechanisms of BM25 for precise lexical search, explore vector embeddings with models like Sentence Transformers, set up a hybrid search environment on Elasticsearch and Pinecone, perform practical exercises on hybrid scoring with real enterprise datasets, create your first combined index with relevance tests, and analyze metrics to identify immediate precision gains.
Module 2Hybrid Search Implementation: Score Fusion and Reranking (Python, LangChain)
Build hybrid search pipelines in Python with LangChain and Haystack, implement weighted fusion of BM25 and cosine similarity scores, integrate reranking techniques with Cohere Rerank, apply to real-world cases like e-commerce or customer support, develop a functional prototype with multilingual queries, measure recall and precision improvements through interactive exercises, and document your algorithm choices for production reuse.
Module 3Hybrid Search Optimization: Tuning and Advanced RAG (Qdrant, Hyperparameter Tuning)
Optimize your hybrid search indexes with BM25 hyperparameter tuning and vector dimension reduction, integrate RAG for retrieval-augmented generation, use Qdrant and Weaviate for scalability, test on massive workloads with 2026 simulations, develop adaptive hybridization strategies based on query type, analyze bottlenecks using profiling tools, and produce a quantified performance report demonstrating 30% latency gains.
Module 4Hybrid Search Deployment: Production and Monitoring for 2026 (Kubernetes, Prometheus)
Deploy your hybrid search engine on Kubernetes with CI/CD using GitHub Actions, set up monitoring with Prometheus and Grafana for real-time metrics, integrate A/B testing for live validation, simulate 2026 AI edge cases like multimodal search, finalize an ongoing project with real enterprise data, present deliverables including source code and dashboard, and plan maintenance for rapid ROI.
Evaluation method

Registration is possible up to 48 business hours before the start of training. All our programs are built for corporate L&D budgets and delivered onsite or remotely.
Our method
Training quality, guaranteed at every step
Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.
You meet the trainer beforehand
30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.
- Live briefing on goals and team context.
- Veto right — we swap the trainer for free if needed.
Content tailored to your context
No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.
- Hands-on cases drawn from your stack and projects.
- Program co-written then validated by your team.
Continuous quality follow-up
Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.
- NPS, knowledge quizzes and skills self-assessment.
- Satisfaction guarantee: fully satisfied or free rework.
A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
