Our Methodology
Every engagement follows the same rigorous process — Agile delivery with TDD, contract testing, and observability built in from day one.
AI Feasibility & ROI Scoping
Before writing a prompt, we define the measurable success criteria, latency budget, cost ceiling, and fallback strategy.
- Use-case prioritisation matrix
- Model cost modelling
- Latency budget definition
- Baseline accuracy benchmarking
RAG Architecture Design
We design the document chunking strategy, embedding model selection, hybrid search configuration, and retrieval re-ranking pipeline.
- Chunking strategy evaluation
- Embedding model benchmarking
- Hybrid search (BM25 + dense)
- Metadata filtering design
Prompt Engineering & Evaluation Harness
Every prompt is versioned and evaluated against a golden dataset using RAGAS or custom metrics before shipping.
- Prompt versioning (LangSmith)
- RAGAS evaluation pipeline
- Hallucination detection
- Output schema validation (Instructor)
Observability & Cost Control
Token cost dashboards, latency P95 alerting, and automated red-teaming run continuously in production.
- LangSmith / Langfuse tracing
- Token cost Prometheus metrics
- PII redaction middleware
- Automated adversarial probing
Tech Stack
Battle-tested tools chosen for production reliability — not for the conference talks.
Why Work With YakshLabs
9 years of lead engineering across 20+ enterprise systems. We bring architecture expertise, production scars, and a delivery process that makes outcomes predictable — not hopeful.
Book a Free Strategy CallWe Use RAGAS — Not Vibes
Our AI systems ship with a formal evaluation harness. Faithfulness, answer relevancy, and context precision are measured on every deployment.
Model-Agnostic Architecture
We build abstraction layers that let you switch from GPT-4o to Claude to an open-source model without rewriting business logic.
AI Safety is an Engineering Discipline
Output validation, PII scrubbing, jailbreak detection, and rate limiting are built into the service layer — not the prompt.
What You Get
Every engagement delivers concrete, ownable artefacts — not just a working system.
