Throughout the project, I onboarded and mentored a junior backend developer, ensuring smooth maintenance going forward.

Results

The middleware significantly improved application performance, reduced load on the model servers, and enhanced security. The junior developer successfully took over maintenance, ensuring long-term sustainability.

Overview

Assisted in setting up the technical foundation for a new truck delivery project, including interviewing and onboarding NestJS engineers.

Challenges

The project needed to quickly establish a solid technical foundation and onboard skilled developers to create a scalable delivery tracking system from scratch.

Our Solution

I assisted in interviewing and onboarding NestJS engineers, created the initial workflow, and established the technical vision for the first few development sprints. I also developed several reusable features that formed the basis of the application architecture, using NestJS, Kubernetes, Docker, and Vue.js.

Results

The project successfully launched with a solid technical foundation. The team was able to work efficiently with clear direction, and the reusable components I created accelerated development across multiple features.

Overview

Led a team of engineers in creating a pipeline for collecting information from Twitch and YouTube and binding them into structured course results.

Challenges

A pre-existing project needed to efficiently collect, process, and organize streaming content from multiple platforms into a cohesive educational format.

Our Solution

I assisted by leading a team of one backend developer and one data engineer in creating a comprehensive pipeline. The system collected information from Twitch and YouTube through their respective APIs, processed the content, and organized it into structured course materials.

Results

The pipeline successfully transformed streaming content into valuable educational resources, significantly expanding the platform's content library with minimal manual intervention.

Overview

Maintaining a legacy OpenedX application and its associated microservices ecosystem.

Challenges

The educational platform required careful maintenance of its legacy OpenedX codebase while supporting the microservices architecture that had been built around it.

Our Solution

I took responsibility for maintaining the legacy OpenedX application, ensuring its stability and performance. Additionally, I managed the microservices ecosystem, implementing improvements and resolving issues as they arose.

Results

The platform maintained high availability and performance, with reduced technical debt and improved integration between the legacy system and newer microservices.

Overview

Developed a comprehensive fuel tracking system for an embassy to monitor and manage their fleet fuel consumption, maintenance schedules, and related expenses.

Challenges

The embassy needed a centralized system to track fuel usage across their diverse fleet of vehicles. The existing manual process was error-prone and inefficient, making it difficult to prevent waste and ensure accountability.

Our Solution

I built a robust Django-based application containerized with Docker. The solution featured a user-friendly interface using jQuery and CSS3 for a responsive design that worked across all devices. The system included role-based access controls, real-time reporting, and comprehensive audit trails.

Results

The new system provided complete visibility into fuel usage patterns, helping identify inefficiencies and reducing overall fuel costs by 25%. Administrative time spent on fuel management was reduced by 70%, while accuracy of tracking improved dramatically.

Overview

Developed a market analysis platform for AMS Pharmaceuticals to track industry trends, competitor activities, and market opportunities.

Challenges

AMS needed to consolidate diverse market data sources into actionable intelligence. Their analysts were spending excessive time gathering and formatting data rather than performing analysis and generating insights.

Our Solution

We created a Django-based platform that automated data acquisition, processing, and visualization. The application integrated multiple data sources and presented insights through interactive dashboards built with jQuery and modern CSS3 techniques. The entire solution was containerized using Docker for easy deployment and scaling.

Results

The platform reduced analysis preparation time by 65% while improving data accuracy. Decision-makers gained access to real-time market insights, helping identify new opportunities that increased market share by 12% within the first year.

Overview

Led development of Ahlibank digital account creation system, enabling customers to open new bank accounts seamlessly across web and mobile platforms.

Challenges

Ahlibank needed to modernize their account opening process, which was previously paper-based and required branch visits. They wanted a solution that maintained strict banking security standards while providing a frictionless user experience.

Our Solution

We built a comprehensive system using Django and Django Rest Framework for the backend, with React for web and React Native for mobile interfaces. I personally led a team of freelance mobile engineers, stepped up as both Business Analyst and Engineer, handled client communication, and managed the backend development.

Results

The new system reduced account opening time from days to minutes, increased new account applications by 35%, and significantly improved customer satisfaction scores. The solution also reduced operational costs associated with manual account processing.

Overview

Developed and led the team behind Ezad.ae, the premier online auction marketplace for premium date fruits in the Middle East region.

Challenges

Creating a reliable real-time auction system that could handle significant traffic spikes during harvest seasons, while managing complex logistics for a perishable product. The project required numerous integrations with payment processors, shipping services, and inventory systems.

Our Solution

Initially attempted to transition to a full technical PM role but switched back to lead engineer. Created a monolithic Django application with DRF backends, jQuery frontend, and deployed on AWS using Kubernetes with Helm. Led a diverse team of 3 backend developers, 2 mobile developers, 1 frontend developer, and 2 QA engineers.

Results

The platform successfully processes millions of dollars in date fruit auctions annually, with 99.9% uptime even during peak seasons. The system reduced transaction costs compared to traditional auctions while expanding market reach to international buyers.
