Project history
The client, a leading multinational telecom, faced user dissatisfaction due
to an outdated billing system with a clunky interface and operations.
Improved system scalability by 40% by migrating the billing
application to a cloud infrastructure, ensuring higher availability,
scalability, and a reduction in operational costs.
Decreased bug resolution time by 50% through the
implementation of automated tests, significantly enhancing the
speed and efficiency of bug detection and resolution.
Reduced Security Incidents by 80% by encrypting the data end to
end, to protect sensitive customer billing information.
Skills: TypeScript, React.js, Next.js, REST APIs, ECS, Storybook, Pulumi,
ECR, Cloudfront, ALB, CloudBees, Docker, Cypress, RTL.

The client, an AI firm in aerospace and defence, faced rising costs from
managing and searching vast internal document archives.
Improved efficiency from an average of 2 hours to 5 minutes
per employee by creating a new web application tailored to modern
requirements that is responsive and intuitive.
Boosted development speed by 50% by automating testing and
deployments.
Increased web performance by 60% by breaking up the code into
smaller parts, using compression techniques, storing frequently
used data for quick access, and making images smaller and faster to
load.

The client, an AI aerospace and defence firm, struggled with a flawed
frontend app, leading to poor user experience and rising customer
turnover in a competitive market.
Improved user experience by 5X and increased the turnover by
15% by implementing a user-centric design approach to overhaul
the frontend, focusing on intuitive navigation, modern aesthetics,
responsive design, and accessibility standards.
Enhanced development experience by 3X by upgrading the entire
codebase to a statically typed system, resulting in easier future
refactoring, improved type safety, and superior error handling.
Led a team of 3 developers and actively conducted knowledgesharing
sessions with both the team and upper engineering
management to accelerate the onboarding and adoption of the new
solution.
