Internal logistics routing system for a global distribution client; optimized shipment routes by cost and distance.

• Built and deployed AWS Lambda functions for route calculation; configured API Gateway with request throttling, authorisers, and SQS-based async processing;
• Developed a product tracking system and order processing algorithms handling complex multi-leg shipment scenarios with cost-optimisation logic;
• Designed MongoDB document schema for high-volume shipment event logs; introduced TTL indexes and aggregation pipelines for operational reporting;
• Implemented JWT-based authentication flows and API key management for multi-tenant partner integrations, following OAuth 2.0 standards;
• Set up Datadog APM and custom metrics for Lambda cold-start monitoring and end-to-end shipment latency tracking;
• Wrote comprehensive automated test suites covering route calculation edge cases; conducted regular code reviews to enforce engineering standards.

B2B platform connecting cargo shippers with freight carriers for on-demand transportation brokerage.

• Built the Django REST backend for the cargo transportation platform, including shipment lifecycle management, carrier matching, and order state machines;
• Integrated payment solutions (Stripe API) with webhook-based reconciliation to handle multi-party transaction flows between shippers and carriers;
• Implemented Celery task queues for asynchronous shipment status polling and carrier notification delivery;
• Designed PostgreSQL schema for a multi-tenant data model, enforcing row-level isolation between client organisations;
• Set up CI/CD pipelines using Docker and GitHub Actions, reducing deployment lead time and enabling reliable staging environment promotion.

Ground control software and computer vision systems for unmanned aerial reconnaissance drones.

• Developed a Linux-based ground control station shell in Python, handling real-time telemetry ingestion and command dispatch to drone hardware over serial and UDP protocols;
• Built computer vision components with OpenCV for automated target detection and image annotation pipelines, processing live video streams from aerial feeds;
• Implemented a Flask REST API to bridge drone telemetry data with a Django-backed management dashboard, including authentication and role-based access control;
• Designed MySQL schemas for mission logging, flight path recording, and sensor event storage with time-series query optimisation;
• Wrote Celery workers for background processing of recorded flight data and generating post-mission analytics reports.

B2C web platform for specialty exotic fruit sales, built end-to-end from design to deployment.

• Built the full e-commerce backend from scratch using Django: product catalogue, inventory management, cart, checkout, and order tracking;
• Integrated third-party payment gateways with webhook handlers for async payment confirmation and order fulfilment triggers;
• Designed a PostgreSQL schema supporting product variants, category hierarchies, and promotional discount rules;
• Worked closely with designers to translate UI/UX mockups into server-rendered Django templates.
