Java Developer

Led a team worked on the UAE government owned crypto exchange systemsoftware infrastructure. In my previous role at a digital currency exchange, I led a team of software engineers tasked with delivering and maintaining critical application software infrastructure services. As the team leader, I managed and motivated a group of skilled professionals to design, develop, and optimize the exchange’s infrastructure, ensuring it was robust, scalable, and secure. My leadership drove the successful execution of key initiatives, including foundational library upgrades and the development of trading indices to meet compliance requirements. Infrastructure Upgrades One of my primary responsibilities was overseeing the upgrade of foundational libraries and tools, such as Nacos, Kafka, MySQL, Redis, and ElasticSearch on AWS. These upgrades were essential to improving system performance, reliability, and security. Key efforts included: MySQL Upgrade: I led the transition from MySQL 5.7 to 8.0, optimizing database queries and indexing strategies. This resulted in faster transaction processing and enhanced data security. Kafka Enhancement: My team improved Kafka message queues, boosting message processing efficiency and ensuring high availability during peak trading volumes. Redis and ElasticSearch Improvements: We upgraded Redis and ElasticSearch to enhance caching and search capabilities, enabling quicker data retrieval and an improved user experience. These upgrades significantly increased the exchange’s operational efficiency, allowing it to handle growing transaction demands without compromising performance. Trading Indices for Compliance Another critical project under my leadership was the development and implementation of trading indices, such as market depth, trading volume, and price volatility metrics. These indices were vital for meeting regulatory compliance requirements and providing users with transparent market insights. I guided my team to ensure these indices were accurate, delivered in real-time, and aligned with industry standards. This work enabled the exchange to operate within legal frameworks while building trust with its users. Collaboration and Problem-Solving Throughout these projects, I fostered collaboration with cross-functional teams, including product managers, compliance officers, and operations staff, to integrate upgrades and features seamlessly. I also tackled complex challenges—such as software compatibility issues and large-scale data processing—through thorough research, rigorous testing, and continuous optimization, ensuring successful outcomes. Impact The results of our efforts were transformative: The infrastructure upgrades created a more reliable and efficient system, capable of supporting increased trading activity without downtime. The trading indices ensured full regulatory compliance, reducing legal risks and strengthening the exchange’s credibility. Ultimately, these improvements delivered an enhanced user experience, with faster transactions and transparent market data.
