OpenSearch Development & Integration
Custom extensions, API integrations, and seamless embedding into your system landscape.
Standard software often covers 90% – we close the last gap. We develop Plugins, connect OpenSearch with your tools, and automate workflows.
Our Development Services
From API integration to complete custom solutions – we cover the entire spectrum.
API & Interface Integration
We make your systems talk to each other. Whether REST, GraphQL, or webhooks – we connect software with your CRM, ERP, or identity provider.
- Bidirectional data synchronization
- Third-party system connections
- Custom webhooks & event handlers
- Legacy system integrations
Custom Middleware & Logic
Often data formats from System A don't match System B. We develop middleware that sits in between, transforms data, and controls processes.
- Transformation layer (ETL)
- Data stream validation
- Caching layer for performance
- Microservices architecture
Embeddings & Custom Apps
Want to use software features in your own intranet or customer portal? We embed software headlessly and build custom UIs around it.
- White-label integration
- Custom dashboards (React/Vue)
- UI extension via plugins
- Mobile app customizations
Automation & Bots
Save manual work through intelligent automation. We develop bots and scripts that handle tasks automatically.
- ChatOps & slash commands
- Automated reporting
- Workflow orchestration
- Trigger-based actions
Advanced Search Engineering
Search is more than `SELECT *`. We optimize OpenSearch for relevance, performance, and AI-powered vector search.
Search Pipelines
Manipulation of queries before execution. We develop request processors that enrich synonyms, correct typos, or analyze user intent.
Ingest Pipelines
ETL directly in the cluster. We write ingest processors that enrich documents upon indexing (GeoIP, NLP sentiment, PII masking).
Vector Search (k-NN)
Implementation of semantic search via k-NN plugin. We connect OpenSearch with embedding models for RAG applications.
Concrete Use Cases
How we implement OpenSearch development in practice.
RAG Knowledge Base
LLMs hallucinate without context. Vector databases are complex to manage.
OpenSearch as hybrid search store (keyword + vector). Optimized retrieval queries for precise LLM answers.
E-Commerce Search Tuning
Customers don't find products when they misspell technical terms or part numbers.
Custom N-Gram tokenizers and phonetic analysis that finds 'screwdriver' even with dialect/typos.
Development with Foresight
Update-safe, scalable, and secure – why you should trust us with your development.
Update-safe (No Core Hacking)
We don't modify the open-source software's source code. Instead, we use official APIs and plugin architectures. Your installation remains updatable and maintainable.
Full-Stack Expertise
We understand not just the code, but the infrastructure beneath it. Our developers know how queries affect database performance and how to build scalable APIs.
Modern Tech Stack
We use modern, type-safe technologies: React, TypeScript, Node.js, Python, Go. Plus PostgreSQL, Redis, and Docker/Kubernetes for infrastructure.
Security by Design
Every line of code is written with security in mind. Input sanitization, secure authentication (OAuth2/OIDC), and compliance with data protection regulations are standard.
Our Tech Stack
How We Work
From requirements to go-live – transparent and structured.
Analysis
We review API documentation, analyze your requirements, and identify optimal integration points.
Architecture
We design the solution: middleware, plugin, or script. Data flows, interfaces, and security concept are defined.
Development
Agile implementation with code reviews, automated tests, and continuous coordination. You see progress in real-time.
Deployment
Integration into your CI/CD pipeline or hosting on our infrastructure. Documentation and training included.
