CGPA · AI & Data Science (2027)
I am an AI developer and systems engineer focused on turning probabilistic model outputs into predictable, production-grade software. Rather than treating foundation models as black boxes or building superficial wrappers, I engineer the backend pipelines, guardrails, and evaluation harnesses that make AI dependable under real workloads.
My engineering philosophy centers on deterministic reliability over raw prompt optimism, defense-in-depth security to neutralize prompt injections and sensitive data leakage before execution, and traceable evaluation using automated regression suites and strict schema contracts.
Stateful agent loops with structured tool-calling boundaries, async streaming generators, token-budgeted context windows, and deterministic fallback paths.
Multi-tenant vector search with pgvector (HNSW) paired with sparse BM25 lexical ranking, Reciprocal Rank Fusion (RRF), and cross-encoder re-ranking.
Pre-execution prompt sanitization, heuristic injection defense, token leakage filters, and PII redaction operating locally without external latency.
Deterministic assertion suites for agent step sequences, schema contract testing with Pydantic/Zod, synthetic regression harnesses, and CI/CD quality gates.
Production AI platforms, autonomous reliability frameworks, and in-process LLM security engines backed by documented benchmarks and automated test suites.
Hybrid retrieval, context orchestration, and citation-grounded LLM synthesis for complex enterprise documents.

FastAPI CI/CD Lab Workflow
Production-grade Python libraries authored and published on the Python Package Index (PyPI). Designed for real production pipelines with strict typing, deterministic contracts, sub-millisecond execution, and automated CI/CD.
llmfirewall-core•Import:import llmfirewallLLMFirewall Core (llmfirewall-core) is published strictly as an installable in-process Python library. It is not a hosted SaaS, remote proxy, or web dashboard — all adversarial threat mitigation, entropy analysis, and Policy-as-Code checks execute natively in host process memory with sub-millisecond (+0.022ms) overhead.
A lightweight, provider-agnostic security and policy enforcement layer for LLM, RAG, and AI-agent applications. Executes in-process threat scanning to intercept adversarial prompt injections, redact sensitive credentials and PII, and enforce Policy-as-Code with sub-millisecond overhead (+0.022ms).

Distribution: aireliability
An open-source reliability and regression-testing framework for LLM applications and AI agents. Replaces subjective vibe-checks with programmatic assertions across tool-invocation sequences, argument validation schemas, execution traces, and cost ceilings.
airel command-line runner for automated GitHub Actions release gates.Traces LLM outputs, function call payloads, and execution latency.
Verifies strict Pydantic argument types; rejects malformed tool calls.
Asserts valid invocation order; flags regression spikes in token consumption.
Deterministic pass. Ready for automated production release.
Non-bypassable fail-closed intercept prevents shipping broken agents.
