Building Data Systems That Think and Scale
I combine experience in software development, analytics, and cloud to deliver modern, end-to-end data platforms.
Hi, I'm
My Unique Edge
I’m a cloud and data engineer with a rare combination of business understanding, data infrastructure skills, and software development experience.
My career started in analytics, working as a Tableau reporting analyst. That gave me direct exposure to how data supports business decisions. From there, I moved into backend engineering — first as a data engineer at a bank, then as a consultant at PwC, where I worked on large-scale cloud data projects.
Now, as a cloud developer building AWS Marketplace product, I focus more on software architecture, abstract coding, and integration — allowing me to contribute across the stack, not just in data.
This end-to-end perspective — from reporting to infrastructure to dev — lets me design platforms that are not only scalable and cloud-native, but also practical and user-focused.
In my free time, I’m exploring machine learning and IoT — continuing to connect data with the real world.

Experience
I am currently working as a cloud developer at AWS CEE Partner of the year - Tameshi. I am part of small developers team responsible for CloudIAM, a cloud-native infrastracture and access management platform listed on AWS Marketplace.
- Built and enhanced backend features using Python and FastAPI, following a hexagonal architecture with a clear separation of domain logic and adapters.
- Frequently optimized API endpoints and database repository methods to improve performance, scalability, and maintainability.
- Worked extensively with AWS services including EC2, Lambda, ECS, Aurora, Step Functions, and SSM.
- Used Docker, Git, and GitLab for development and version control within a collaborative core team.
- Contributed to infrastructure as code using Terraform, helping define and manage cloud resources in a consistent, versioned way.
- Regularly involved in debugging, issue resolution, and refining core domain logic in a production SaaS environment.
📌 Real-Time Data Movement Platform – KONE
Served as a core engineer on a global project replacing Mulesoft with a serverless AWS-based DML system, processing over 3 million events daily across 200+ integrations.

Actively contributed to architecture and design decisions in a fast-paced, international environment
📌 Enterprise Data Lake & Migration Project – US Manufacturing Client
Worked in a small, agile team focused on migrating legacy data systems to AWS and implementing a robust Medallion architecture (bronze, silver, gold layers) to support structured analytics and reporting.
Key contributions:
-
Migrated legacy databases using AWS DMS and automated pipelines with Glue and Step Functions
-
Designed end-to-end data workflows integrating S3, Glue, Athena, and Lake Formation
-
Translated complex Alteryx logic into scalable AWS-native transformations
-
Enabled cost-efficient and secure data processing with optimized resource use and IAM policies
-
Created and automated ETL processes using AWS S3, EventBridge, Glue, and Athena to extract, transform, and load data into Tableau dashboards.
-
Developed Python based desktop GUI applications for efficient data integration and business process automation, connecting multiple data sources and automating diverse tasks.
-
Utilized Glue’s ETL capabilities to transform raw data into optimized parquet files, improving data querying performance in Athena.
