Technical Expertise
8+ years of hands-on experience across the full backend stack, data engineering, and cloud infrastructure.
What I Can Build For You
Whether you need a new backend, a data pipeline, or a full product — I bring the technical depth to make it production-ready.
Backend Development
Scalable server-side systems built with Node.js and Python. Microservices, monoliths, event-driven architectures — designed for performance, reliability, and long-term maintainability.
API Design & Integration
REST and GraphQL APIs built for speed and clarity. From public-facing APIs to complex third-party integrations — I design contracts that are intuitive for consumers and solid under load.
Cloud Infrastructure
End-to-end cloud architecture on AWS — compute, storage, serverless, and networking. CI/CD pipelines, auto-scaling, and infrastructure-as-code for reliable, cost-efficient production systems.
AI & Big Data Pipelines
High-throughput data pipelines for real-time and batch workloads using Kafka and Airflow. Computer vision models and ML inference endpoints integrated into production backend services.
Blockchain Development
Smart contract integration and blockchain explorer tooling. I've built middleware layers connecting web apps to Ethereum-based chains and processed on-chain data at scale.
Full-Stack Web Applications
Complete web applications with React and Next.js frontends backed by robust APIs. From MVP to production — auth systems, dashboards, admin panels, and real-time features.

I'm available for freelance, consulting, and full-time remote roles.
Selected Work
A selection of systems and products I've designed and built across my career. Most are proprietary — described at a high level.
Metaverse / VR Backend Platform
Designed and led the backend architecture for a Metaverse and VR product at Netsol Technologies. Built microservices to handle real-time 3D asset delivery, user sessions, and state synchronisation across virtual environments.
Blockchain Explorer Data Pipeline
Built a high-throughput big data pipeline for a blockchain explorer at Nugenesis (Australia). Ingested on-chain events with Kafka, orchestrated ETL workflows with Airflow, and processed data with Python and Scala.
IoT Real-Time Streaming Service
Architected a backend service to capture telemetry from IoT devices and stream data in real time to web dashboards. Used MQTT for device communication and WebSockets for client delivery.
Smart Contracts Integration Layer
Developed a middleware layer that bridged web applications to Ethereum-based smart contracts at Miranz Technologies. Enabled seamless read/write interactions with on-chain state from a Node.js backend.
Multi-Tenant MERN Web Platform
Built a scalable multi-tenant web platform using the MERN stack with role-based access control, real-time notifications, and a modular service architecture designed for high availability.
Computer Vision Pipeline
Developed a computer vision processing pipeline using Python for image classification and object detection. Integrated with a REST API to expose model inference endpoints for client applications.
