About

Currently working as a lead member of technical staff and leading the development of a web automation testing platform. I have experience working with Golang, Java, Kafka, MySQL, Redis, AWS, event-driven architecture and distributed systems. I graduated in 2020 with a major in Mathematics and Computing, which was a rigorous course and required critical thinking. My passion in tech is to work on products or problems that directly or indirectly help people. I am very excited and open to learning new tech stacks. I am looking for more variety and challenging work.

Architected a high–performance WebSocket proxy server in Go for bidirectional communication. Used goroutines,
custom buffer management, and auto–reconnect logic, reducing connection failures by 90% and boosting resilience.
Developed a Node.js SDK that enables clients to execute tests on remote cloud infrastructure through a seamless
integration layer, requiring zero codemodifications. Reduced integration time by 80 per cent for 50+ enterprise clients.
Accomplished a 50 per cent reduction in data storage costs by revamping the artefact management system through
integration of a cloud storage solution using Golang and AWS S3.
Mentored new hires and juniors, accelerating onboarding and reducing team ramp–up time by 30%
Engineered a JavaScript plugin to detect web accessibility issues using Node.js, Kafka, and OpenSearch. Integrated
real–time listeners and command interception, identifying WCAG violations and boosting enterprise sales by 15%.
Spearheaded geo–proxy enhancements, reducing latency by 15ms and slashing infrastructure costs by 40%.
Optimised downloading of artefacts from S3 through CloudFront, reducing 80,000 network calls per day to S3, thus
lowering cost. This optimisation also improved data retrieval efficiency and overall system performance.
