Optiven Internal Portal

Overview

At Optiven Limited, I designed and maintained a suite of responsive internal systems that serve as the operational backbone for the company's departments. The platform enables seamless real-time data synchronisation, replacing manual processes and reducing inter-department communication overhead.

Working in a fast-paced agile environment, I partnered with stakeholders to align technical solutions with business goals, and conducted performance optimisations and code refactoring that significantly improved system scalability and reliability.

Key Features

Real-time Data Synchronisation

Cross-department data sync via real-time API integrations, ensuring all teams work from a single source of truth with minimal latency.

API Integration Layer

Implemented real-time REST API integrations that reduced downtime and enhanced operational efficiency across the organisation.

Performance Optimisation

Conducted systematic code refactoring and performance tuning, cutting system bottlenecks and ensuring the platform scales with growing data volumes.

Responsive UI

Built responsive React interfaces that work across desktop and mobile, giving all staff access to the tools they need wherever they are.

Technical Implementation

Full-Stack Architecture

Built with React on the frontend and Node.js on the backend, communicating via REST APIs. PostgreSQL serves as the primary database, with optimised queries ensuring fast reads across large datasets.

Stack: React → Node.js REST API → PostgreSQL → Real-time Sync

Database Design

PostgreSQL with carefully structured schemas and indexing strategies to support complex cross-department queries at scale, minimising query times for high-traffic operations.

Agile Delivery

Delivered features iteratively in a high-paced agile environment, working directly with stakeholders to prioritise business impact and ensure technical solutions mapped to operational goals.
