I’m a Backend, DevOps, and AI/ML Engineer focused on building scalable, production-grade systems powered by cloud infrastructure and intelligent models.

I design and deploy end-to-end architectures—from frontend interfaces to backend APIs, machine learning services, and cloud-native infrastructure.

I’ve built and deployed systems like:

Waiterix — an AI-powered restaurant automation and voice ordering platform with real-time processing and dynamic GPT-based interactions

Nomagro — a data-driven platform with predictive models, analytics dashboards, and intelligent APIs

⚙️ Engineering & Infrastructure Focus

I work extensively with modern backend systems and AWS cloud infrastructure, including:

☁️ Cloud & DevOps (AWS):

EC2 (compute & scalable deployments)

VPC, Subnets (public/private architecture)

NAT Gateways (secure outbound traffic)

Route 53 (DNS & domain routing)

API Gateway (serverless APIs)

Lambda (serverless compute)

S3 (object storage)

CloudWatch (logging, monitoring, alerting)

DynamoDB (NoSQL serverless database)

ElastiCache / Redis (caching & real-time performance)

IAM (access control & security)

🧠 Backend & Systems:

FastAPI, Node.js (Express)

REST APIs & WebSockets (real-time systems)

Authentication (JWT, OAuth flows)

Microservices & modular architecture

Event-driven systems & webhooks (e.g., VAPI integrations)

📊 AI / Machine Learning:

Predictive modeling & time-series forecasting

Model deployment via APIs

Data pipelines & preprocessing systems

🗄️ Data & Storage:

MongoDB (Mongoose)

DynamoDB

Redis caching layers
