AI & Data Systems Engineering (Production RAG)
Deterministic, zero-hallucination AI pipelines, vector retrieval architectures, and LLM rate-limit management.
Practice Overview
We turn raw LLMs and embeddings into production systems with deterministic guardrails, verified source grounding, and predictable operating costs. We specialize in high-stakes domains (education, legal, fintech) where hallucinations and out-of-context answers are unacceptable.
Core Engineering Capabilities
- •Deterministic RAG Engines: Retrieval-Augmented Generation pipelines linking every generated response to verified source citations.
- •Vector Database Architecture: Chunking strategies, semantic indexing, and high-dimensional search using Pinecone and Qdrant.
- •Cognitive Taxonomy Balancing: Programmatic enforcement of Bloom's Taxonomy and curriculum standards across assessment models.
- •Cost Governance & Budget Caps: Token-bucket rate limiting, semantic caching of LLM responses, and prompt optimization.
- •Multi-Modal Assessment Pipelines: KaTeX mathematical formula rendering and bilingual font rendering (Devanagari script).
Primary Technologies
Industry Best Practices Guaranteed on Every Project
We uphold rigorous engineering standards across architecture, security, automation, and code cleanliness on every engagement:
Every statement or question generated by the engine must link to verified chapter and page numbers from official curriculum textbooks.
Strict input sanitization, prompt separation, and Pydantic/Zod schema enforcement on all LLM JSON output streams.
Combining BM25 keyword matching with dense vector embeddings and cross-encoder re-ranking for superior retrieval precision.
Strict rate limits per user/IP, caching frequent query embeddings in Redis, and avoiding redundant LLM API invocations.
Continuous testing of prompt revisions against curated golden evaluation datasets before deployment to production.
Deterministic fallback to rule-based templates or secondary model tiers when primary model APIs experience latency spikes or outages.
Verified Project Proof Point
A 90-second exam generation engine balancing cognitive levels and referencing NCERT textbooks with zero hallucinations.
