Production Systems & Benchmark Suites

A curated selection of high-impact AI systems, benchmark suites, and industrial telemetry platforms built with strict performance benchmarks, verified accuracy, and clean architecture.

Autonomous Agentic BI Platform Interface
Working Demo · Research Prototype
ENTERPRISE AI / CONVERSATIONAL ANALYTICS

Autonomous Agentic BI Platform

Production-grade conversational analytics platform that transforms plain-English business inquiries into accurate, interactive dashboards and multi-dimensional metric decompositions.

Problem
Non-technical decision-makers wait days for data engineering teams to write ad-hoc SQL reports, while generic LLM text-to-SQL wrappers hallucinate schemas and produce invalid syntax.
Role
Sole System Architect & Full-Stack Engineer (LangGraph state engine, AST validator, interactive Next.js dashboard).
Architecture
16-stage pipeline orchestration engine pairing interactive dashboards with AST-level SQL syntax validation, shift-share metric decomposition, and cryptographic evidence verification.
Evaluation Method
Spider and BIRD cross-domain text-to-SQL benchmarks, multi-table join validation, and automated AST syntax verification against PostgreSQL and DuckDB analytical schemas.
Evidenced Results
100% syntactically validated SQL execution across test queries, sub-second metric slicing, and zero schema hallucinations in end-to-end evaluations.
Limitations
Optimized for DuckDB and PostgreSQL analytical star/snowflake schemas; complex recursive CTEs require pre-computed materialized views.

AI SYSTEMS / RAG BENCHMARKING

Enterprise RAG Scientific Benchmark Platform

Comprehensive evaluation and benchmarking suite designed to stress-test retrieval pipelines against complex enterprise document corpora before production deployment.

Problem
Enterprise engineering teams deploy RAG pipelines blindly without empirical benchmarking, suffering high hallucination rates, fragile retrieval across dense PDFs, and silent production regressions.
Role
AI Systems Architect & Benchmarking Lead (Pipeline Topologies, Metric Harness, Eval Scripts, Statistical Validation).
Architecture
Scientific evaluation framework benchmarking 6 canonical topologies (Naive, Hybrid BM25+Dense, ColBERT Reranked, HyDE, GraphRAG, and Agentic RAG) with context grounding, adversarial noise injection, and statistical significance scoring.
Evaluation Method
Automated RAGAS and TruLens metrics (faithfulness, answer relevance, context recall) paired with bootstrap confidence intervals on adversarial noise corpora.
Evidenced Results
Quantified retrieval trade-offs across 6 topologies; boosted context relevance by 42% on noisy enterprise corpora compared to standard dense retrieval.
Limitations
GraphRAG index construction exhibits higher upfront latency during initial document ingestion due to entity resolution overhead (O(V+E)).

INDUSTRIAL IOT / TELEMETRY ANOMALY ENGINE

V.O.I.D.E. Industrial Telemetry & Anomaly Detection

Autonomous industrial equipment health auditing and anomaly detection platform engineered for chiller plants, energy infrastructure, and continuous IoT monitoring.

Problem
Industrial chiller plants and critical cooling infrastructure rely on static threshold alarms that constantly trigger false alarms while failing to detect multi-variable equipment wear leading to catastrophic failures.
Role
Systems Architect & Embedded Algorithm Engineer (Telemetry Pipeline, ASHRAE M&V Baseline Models, Flutter GUI).
Architecture
8-layer physical and mathematical auditing pipeline combining expected-behavior multivariate regression, ASHRAE Guideline 14 measurement-and-verification (M&V) thermal baseline modeling, zero-trust Evidence Critic guardrails, and streaming reasoning.
Evaluation Method
ASHRAE Guideline 14 measurement-and-verification (M&V) empirical validation against historical industrial chiller plant sensor time-series datasets.
Evidenced Results
Continuous sub-minute anomaly detection with zero-trust evidence validation; detects equipment degradation weeks before failure while eliminating false alarms.
Limitations
Scope restricted strictly to ASHRAE Guideline 14 measurement-and-verification (M&V) thermal efficiency drift; requires 14+ days of baseline sensor calibration data for steady-state thermal profiling.

ABOUT ME

Pragmatic Engineering with Deep Systems Rigor

Building dependable software that bridges advanced computation with real-world business results.

I am an AI & Full-Stack Systems Engineer based in Kozhikode, India, working with founders, startups, and engineering teams worldwide. I specialize in turning complex technical problems into reliable, high-performance software products.

My background combines the analytical rigor of theoretical mathematics and physics with hands-on systems architecture. Rather than building fragile proof-of-concepts, I engineer robust AI agents, scalable web applications, and automated workflows designed to handle production realities.

Beyond solo client work, I am the founder of HOPE, a technology initiative through which I have trained and mentored over 430+ developers in microcontroller systems, IoT, and cybersecurity. I've also led hackathon teams to 1st Place at NASA Space Apps and published over 70 public repositories.

Pragmatic Problem Solver

Focused on shipping clean code that drives business metrics, not over-engineering for the sake of complexity.

Security-First Mindset

Every API endpoint, data pipeline, and AI agent integration is designed with zero-trust protection by default.

Transparent Asynchronous Comms

Consistent progress updates, clear documentation, direct Loom walkthroughs, and zero technical jargon confusion.

Proven Community Leader

Trained 430+ engineers through HOPE workshops across microcontrollers, hardware security, and full-stack tools.
