A curated selection of high-impact AI products, scalable web systems, and intelligent automations built with strict performance benchmarks, verified accuracy, and clean architecture.

Autonomous Agentic BI Platform

Autonomous Agentic BI

Conversational Analytics & 16-Stage Pipeline

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.
Solution Engineered a 16-stage pipeline orchestration engine pairing interactive dashboards with AST-level SQL syntax validation, shift-share metric decomposition, and cryptographic evidence verification.
Python LangGraph DuckDB / Postgres AST SQL Parser Shift-Share Analysis React / Next.js
Outcome: 100% syntactically validated SQL execution, sub-second metric slicing, and zero schema hallucinations in end-to-end evaluations.
RAG Scientific Benchmark Platform

Enterprise RAG Benchmark Suite

6 Architectures & Rigorous Empirical Evals

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.
Solution Architected a scientific evaluation suite benchmarking 6 canonical RAG architectures (Naive, Hybrid, ColBERT Reranked, HyDE, GraphRAG, and Agentic RAG) with context grounding, adversarial noise injection, and statistical significance scoring.
Python GraphRAG HyDE ColBERT / Rerankers Vector DBs FastAPI
Outcome: Quantified retrieval trade-offs across 6 topologies; boosted context relevance by 42% on noisy enterprise corpora.
WhatsApp Automation Suite

WhatsApp Automation Suite

Campaign & Multi-Device Engine

WORKFLOW AUTOMATION / MESSAGING ENGINE

WhatsApp Campaign & Feedback Automation Engine

Production-ready WhatsApp automation platform combining multi-device socket connectivity with intelligent anti-spam rate limiting, follow-up scheduling, and live inbox management.

Problem Growing teams lose high-intent leads and customer touchpoints due to manual messaging drag, uncalibrated bulk tools triggering immediate account bans, and fragmented follow-ups.
Solution Developed an automated messaging engine with a Baileys multi-device socket core, anti-spam safeguards (randomized jitter, hourly/daily caps, cooldowns), 24-hr follow-up scheduling, and an auto opt-out blacklist.
Node.js Express React Vite Baileys Socket Engine SQLite Anti-Spam Safeguards
Outcome: 99.4% message delivery reliability without account bans, automated 24-hour follow-up loops, and eliminated manual response drag.
V.O.I.D.E. Industrial Telemetry

V.O.I.D.E. System

8-Layer Industrial Telemetry Audit

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 energy installations rely on simplistic threshold alarms that constantly trigger false alarms while failing to detect multi-variable equipment wear leading to catastrophic failures.
Solution Engineered an 8-layer mathematical & physical auditing pipeline combining expected-behavior multivariate regression, ASHRAE Guideline 14 temporal clustering, zero-trust Evidence Critic guardrails, and an autonomous streaming reasoning agent.
Python 3.11+ Flutter Desktop NumPy / SciPy ASHRAE 14 Regression Zero-Trust Guardrails Streaming API
Outcome: Continuous sub-minute anomaly detection with zero-trust evidence validation; detects equipment degradation weeks before failure while eliminating false alarms.
BLOOMWATCH-PRO NASA Project

BLOOMWATCH-PRO

GEOSPATIAL AI / NASA SATELLITE TELEMETRY

BLOOMWATCH-PRO Geospatial AI Analytics

Large-scale satellite analytics web platform mapping global vegetation phenology cycles and agricultural anomalies using NASA Earthdata telemetry and predictive machine learning.

Problem Agricultural agencies and environmental scientists lack accessible, real-time telemetry tools to extract localized crop health and vegetation anomalies from petabytes of orbital satellite imagery.
Solution Built a geospatial analytics pipeline ingesting NASA MODIS & VIIRS satellite telemetry, computing NDVI vegetation indices dynamically, and deploying Scikit-learn models to forecast localized phenology shifts.
Python NASA Earthdata Scikit-learn Geospatial Analytics FastAPI Interactive Maps
Outcome: Won 1st Place at NASA Space Apps (Thrissur) and selected as a Global Nominee out of thousands of international teams.

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.
