Proof of Engineering Thinking

System Architecture Decisions

How I design scalable, maintainable systems

// MaatiGyan Architecture
WhatsApp Bot → Express API → ML Spectral Model → RAG Engine → Bangla Response

// Booking Platform
Next.js SSR → Prisma ORM → PostgreSQL → Stripe Webhooks → Admin Dashboard

// e-FuelCard
React SPA → Node.js API → MongoDB → JWT Auth → Role-Based Access

I prioritize separation of concerns, API-first design, and horizontal scalability. Every system I build assumes it will need to handle 10x growth.

AI Experimentation Log

Iterative AI development and validation

// RAG Pipeline — MaatiGyan
1. Farmer query (Bangla) → Translation layer
2. Pinecone vector search → Context retrieval
3. GPT synthesis → Bangla crop recommendation

// Cold Pitch AI — GPT Pipeline
Recipient data → Prompt engineering → 3 email variants → Tone adjustment

Database Design Philosophy

Schema design and optimization strategies

// PostgreSQL — GearTrackr
TABLE assets (id, name, assigned_to, due_date)
TABLE audit_logs (id, asset_id, action, timestamp)

// Prisma — Booking Platform
Relational design with Service ↔ Booking ↔ Payment

Deployment & DevOps Workflows

CI/CD, containerization, and monitoring

// Deployment Matrix
MaatiGyan → Render (Docker)
e-FuelCard → Vercel (Edge)
Booking → Vercel + Supabase
GearTrackr → Netlify + Supabase
Cold Pitch AI → Netlify
