Featured Projects

Hands-on evidence of software architecture, data modeling, and operational telematics systems built to solve real-world problems.

Fleet Operations & Fuel Control

Navix Fleet

Status:Active Development / MVP

Fleet management and fuel-control software focused on operational visibility, reconciliation, and efficiency.

Navix Fleet desktop dashboard showing fuel efficiency graphs, route status, and vehicle metrics

1. Operational Problem

Fleet operators and dispatchers often rely on fragmented paper receipts and loose spreadsheets to monitor fuel consumption and vehicle maintenance. This leads to undetected fuel shrinkage, inaccurate mileage-per-liter estimates, missed oil/tire service intervals, and unaccountable driver assignments.

2. My Responsibility

Full-Stack Software Engineer & Technical Architect

3. Verified Outcomes

Eliminates disconnected spreadsheets by centralizing fuel and maintenance in one database
Automates cost-per-kilometer calculations without manual data crunching
Provides structured audit logs for vehicle handover between drivers

4. Key Solution Features

Automated fuel consumption anomaly detection comparing tank capacity vs odometer delta
Driver-vehicle assignment management with shift-based logging
Preventative maintenance schedules triggered by real engine mileage thresholds
Exportable operational reports for monthly fleet expense reconciliation

5. Technical Scope & Architecture

•Django REST Framework backend with role-based permissions
•PostgreSQL database with schema-level audit trails and temporal tracking
•Vue.js single-page administrative dashboard with reactive KPI charts
•Automated fuel purchase reconciliation algorithms against odometer readings
•Containerized deployment workflow using Docker and Nginx

GPS Tracking & Telematics

Navix Tracker

Status:Live Production

GPS tracking and telematics platform for vehicle monitoring and related fleet features.

Navix Tracker live telematics map interface showing active vehicle markers, geofence polygons, and telemetry metrics

1. Operational Problem

Commercial vehicle tracking requires reliable multi-protocol hardware communication across thousands of concurrent devices, sub-second latency for moving assets, and immediate event notifications (speeding, ignition, geofencing) without server crashes or high CPU overhead.

2. My Responsibility

Telematics Infrastructure Engineer & Platform Integrator

3. Verified Outcomes

Proven production stability under sustained multi-device telemetry reporting
Instant event notification delivery through configured SMS and email gateways
Complete white-label separation allowing resellers to serve end-clients under their own brand

4. Key Solution Features

Real-time vehicle map tracking with live speed, ignition status, and direction vectors
Interactive geofence polygon and circular boundary creator with instant breach alarms
Historical trip playback with stop duration and speed profile inspection
Custom branded client portals with company logos, custom domains, and white-labeled alerts

5. Technical Scope & Architecture

•High-concurrency Traccar core engine tuning and JVM garbage-collection optimization
•Multi-port TCP/UDP listener configuration for protocols (Teltonika, Coban, Queclink, Concox)
•Reverse proxying with Nginx and SSL termination for WebSocket telemetry streams
•Custom responsive frontend branding with real-time vector map rendering
•Automated event notification pipelines for SMS, Telegram, and Webhook dispatch
