What I'm looking for
I am a dedicated Software Engineer who is passionate about crafting innovative solutions and optimizing complex systems. With a strong focus on microservices architecture and cutting-edge technologies, I have played a pivotal role in developing and maintaining mission-critical components within the financial sector.
My journey as a Software Engineer has centered on creating and nurturing essential microservices that drive a banking product facilitating account openings in the US and KY regions. This involved seamless integration with a strategic partner, harnessing a sophisticated tech stack that includes Kotlin, Ktor, MongoDB, Postgres, AWS Lambda, AWS SQS, AWS SNS, AWS API Gateway, Terraform, GitHub Co-Pilot, Postman, CircleCI, GitHub Actions, REST and more.
My expertise lies in building robust microservices foundations using Kotlin and Ktor, ensuring efficient data storage and management through MongoDB and Postgres. I have a proven track record of successful integration of AWS services, utilizing AWS Lambda, SQS, SNS, and API Gateway to create a solid communication framework between microservices. The adoption of Terraform has allowed me to manage infrastructure as code, ensuring scalability and effective resource management.
Adept at utilizing tools like GitHub Co-Pilot, GitHub Actions, and CircleCI, I have streamlined development processes and maintained a high standard of code quality. Through Postman, I validate microservices interactions, ensuring seamless communication and reliable workflows.
My commitment to excellence extends beyond technology. I excel in collaborating with cross-functional teams, ensuring alignment with organizational objectives and partner expectations. In addition to my role in banking solutions, I have also taken the lead in designing and developing a foreign exchange (forex) product, showcasing my versatility and adaptability.
As a forward-thinking technologist, I am deeply invested in driving innovation and optimizing operations within the dynamic landscape of financial technology. With a proven ability to navigate complex challenges and a passion for staying at the forefront of technological advancements, I am committed to delivering high-quality solutions that make a tangible impact.
