The AI Product Lab
Every product below was built solo using Agentic AI as my engineering team. No traditional dev team. No boilerplate agencies. Just architecture taste, domain expertise, and AI execution velocity.
VirtualSach.in
This very portfolio — built end-to-end with Agentic AI as co-pilot.
A fully interactive personal portfolio built with Astro v5, Cloudflare Workers AI, and D1 database. Every component — from the Terminal CLI modal to the Tech Radar and Post-Mortem Simulator — was designed and implemented using AI. Not generated. Architected.
Agentic AI Platform
Multi-agent orchestration with production-grade reliability engineering.
The platform that runs 100,000+ autonomous AI agent loops daily for enterprise financial clients. Built with stateful Circuit Breakers (borrowed from data center thermal runaway patterns), Capability Attenuation (borrowed from DFW microsegmentation), and BGP-inspired token cost routing.
Virtual Sachin Digital Twin
A RAG-grounded conversational AI clone deployed at the edge.
Not a chatbot. A production-grade AI system that embodies 18 years of infrastructure knowledge through a Vector RAG retrieval engine. Every response is grounded in real war stories, real case studies, and real architectural decisions — cited with direct blog post links.
/blog/ URL citations.Social Brand Manager
The AI-powered brand intelligence engine that runs the strategy behind this portfolio.
A private AI-driven system for managing personal brand strategy, content calendars, career timeline documentation, and opportunity evaluation. Built on a strict 3-Tier Architecture: Portfolio (public), Brand Engine (private), Identity Vault (air-gapped local). AI agents operate within defined capability boundaries — no personal data crosses tier boundaries.
RAG Automated Evaluation Harness
Evaluate the retrieval accuracy, latency, and node precision of the Digital Twin's Vector RAG engine in real time. Clicking the run button executes 7 distinct scenario queries directly against our edge indexing schema, testing for correct semantic keywords and URL resolving.
NetOps & Infrastructure Diagnostics Suite
Interactive network, security, and facility thermodynamics planners.
A comprehensive utility bundle built directly on the portfolio edge infrastructure. Contains four dynamic tools: a BGP path selection policy simulator, a Tier-3 Data Center PAC cooling planner, a stateful Zero-Trust distributed firewall engine, and a cloud Transit Gateway hub topology sizer.
Interact with routing attributes, cabinet thermodynamics, and firewall rules in real-time, matching standard enterprise best practices and your professional engineering timeline.
Incident Command Simulator
Interactive outage scenario diagnostic and decision tool.
Test your engineering intuition in resolving critical enterprise downtime scenarios. Models MTU mismatches across vDS overlay switches, route leakage on dual-homed transit VLAN boundaries, and DNS resolution validation failures in NSX-T Federation synchronization.
Test your ability to diagnose network anomalies under pressure. Evaluates packet headers, routing maps, and DNS records to find the structural root cause of outages.
AI Resume Fit Score
Paste any job description and let the AI Twin execute a real-time semantic analysis against Sachin's 20-year infrastructure and networking career. Employs keyword tokenization mapped to 10 distinct career domains, RAG evidence grounding, and Workers AI Llama models to generate a dynamic fit score and a tailored cover letter introduction.
Provides recruiters and hiring managers with a transparent, honest, and evidence-grounded comparison of requirements versus actual production career accomplishments.
Extended Tool Suite
Several additional production-grade tools built alongside the core platform — from gamified incident war rooms to an AI Digital Twin showreel.
Sub-40ms edge inference on Llama 3.1-8B-Instruct with D1 RAG vector memory indexing 112 war stories. 2-way voice mode via Whisper ASR.
Quantized SmolLM2-135M running 100% locally in your browser. Benchmarked WebGPU matrix operations with WASM fallback for zero-cost edge execution.
6 real-world outage scenarios (ExpressRoute BGP loop, KV stampede, GENEVE MTU drop, NSX Federation sync). Guided RCA with timeline scoring.
Visualize orchestrator → worker agent pipelines with stateful circuit breaker state machines. Real-time message routing and failure injection.
Build CFO-ready Agentic AI business cases. Input team size, incident frequency, and automation targets to model 3-year NPV and payback period.
Live benchmark comparing edge inference (Workers AI) vs origin API latency across 5 Cloudflare PoPs. P50/P95/P99 breakdown with real SSE streaming.
Browser-native terminal with custom commands: `blog list`, `rag search <q>`, `whoami`, and `deploy status`. 20+ supported commands.
