The Techelgo Production Stack: Modern AI & Full-Stack Tooling

Speed of iteration combined with rock-solid stability separates elite software teams from the rest. At Techelgo, our internal developer platform is standardized around high-throughput, battle-tested modern tools. Here is an overview of what powers our production environments.

1. Frontend: Next.js 15 & React 19 Server Components

Next.js gives us the optimal balance between server-side generation, edge caching, and rich interactive interfaces. Leveraging React Server Components drastically minimizes client-side bundle sizes.

2. Backend Services: Python FastAPI & Node.js Microservices

For asynchronous processing and high-concurrency API gateways, FastAPI and modern Node.js runtimes deliver sub-50ms execution times with clean OpenAPI documentation generated out of the box.

3. Vector Databases: Qdrant & Pinecone

When building agentic workflows and retrieval-augmented systems, low-latency approximate nearest neighbor (ANN) search is paramount. We deploy Qdrant for semantic retrieval with high filter precision.

4. Orchestration & LLMs: LangGraph with Claude & OpenAI

Rather than relying on brittle linear prompts, we build cyclical state machines using LangGraph, ensuring multi-agent pipelines can recover from tool errors and self-correct prior to user output.

5. Containerization & Edge: Docker, Kubernetes & Cloudflare

All microservices are containerized with Docker and deployed across auto-scaling clusters, fronted by Cloudflare's global edge network for DDoS mitigation and sub-10ms edge caching.
