ZafTech

ZafTech is an engineering studio specializing in building intelligent, high-performance backend systems and integrating cutting-edge AI (LLMs, RAG) for startups and scale-ups.

We turn complex technical challenges into competitive advantages, focusing on extreme cost efficiency and reliable scalability.

OUR CORE EXPERTISE

We combine deep system-level knowledge with modern AI/ML engineering to deliver full-stack solutions.

1. AI & LLM ENGINEERING
   We architect and deploy proprietary AI solutions, not just API wrappers.

• Custom RAG Pipelines: Building Retrieval-Augmented Generation systems to eliminate hallucinations.
• Vector Database Integration: Selecting and implementing the right vector storage for optimal retrieval speed and relevance.
• Prompt/Cache Optimization: Engineering strategies to reduce LLM API latency and minimize token costs.

1. SCALABLE BACKEND ARCHITECTURE
   We design non-blocking, asynchronous backends ready for production loads.

• High-Concurrency APIs: Expert in Python (FastAPI, LiteStar) and C# (ASP.NET Core) for reliable, fast APIs.
• Microservices & Containerization: Transitioning monolithic apps to containerized services (Docker, GCP Cloud Run) for auto-scaling and resilience.
• System Design & Optimization: Focused on performance metrics and ensuring low latency at scale.

1. STRATEGIC CLOUD & DEVOPS
   Leveraging the cloud to maximize performance while minimizing infrastructure spend.

• Extreme Cost Efficiency: Proven track record of engineering solutions that drastically reduce infrastructure overhead.
• Cloud Deployment: Expertise in GCP (Cloud Run, GCS) and implementing CI/CD with GitHub Actions.
• Data Migration: Zero-downtime strategies for complex data and asset migrations.
