Work Experience
Senior Solutions Engineer
North Labs
- Architected and engineered the application modernization initiatives for our US clients.
- Oversaw and remediated common vulnerabilities and exposures (CVEs) within the AWS accounts of our clients.
- Built secure baselines of the existing cloud infrastructures and reduced operational overheads and maintenance.
- Created secure serverless CI/CD pipelines and incorporated security scanners and linters.
- Suggested and recommended ways to optimize the existing resources based on the AWS well-architected framework.
Data DevOps Engineer
Woven by Toyota, Inc - Data Analytics
- Deployed the standalone, production-grade Airflow Helm release into the company-wide, shared Kubernetes cluster in the Tokyo region. This serves as the ingestion service for our OpenMetadata server.
- Deployed the OpenMetadata Helm release into the same Kubernetes namespace as the Airflow Helm release. This serves as the data catalog platform for all our existing and future data sources in the analytics team.
- Incorporated CI/CD security posture into the GitHub Actions workflows of our infrastructure repository and Airflow DAGs repository, i.e., CodeQL, SBOM, SCA via Snyk, etc.
Full-stack Engineer
Mactan Trikes
- Modernized the entire infrastructure into a service-oriented one, making it more highly available and eliminating the need for database scaling as more data is ingested.
- Applied a new mobile-friendly Bootstrap template for the dashboard and added more capital expenditure budgeting features, which made the client focus more on improving their offline processes to get more investors.
- Created the Metabase insights dashboard for the assets, drivers, payments, and other objects coming directly from the API's database, making drawing out insights from the offline processes of buying more assets more intuitive.
Senior Back-end Python Engineer | Data Lake Company
Atlan Technologies Pvt Ltd
- Managed to resolve support ticket issues in the existing data source connectors of our main Atlan product using Linear.
- Encouraged the orchestration team to create a shared responsibility model between the customer and Atlan to outline a clear boundary of what and what not Atlan can do for the customer when resolving customer issues.
- Upgraded the Argo CLI tool that intends to install Atlan-specific Argo Workflow templates into the different Kubernetes clusters.
- Optimized the Argo Workflow templates' implementations for our Salesforce, Metabase, and Mixpanel data source connector packages.
Advanced Application Engineering Specialist
Accenture
- Led the acquisition of our US-based ERP system built with Python in South Carolina, US.
- Worked as a DevSecOps engineer with one of Accenture's diamond clients.
- Created automation pipelines to streamline our CI/CD operations and Hybris user creations.
- Collaborated with our third-party clients and regional subsidiaries for the ERP integrations.
- Remediated AWS vulnerabilities across teams in Accenture Digital on a bimonthly basis.
- Contributed to periodical code reviews and multiple priority-1 incidents resolutions.
Junior Python Engineer
CollabSpot
- Built cron tasks on Django to automate client push notifications and synchronize CRM data from Google Suite and Office365 to SugarCRM and Dynamics365 CRM.
- Created detection automation of HTML-based email signatures to extract the data about the prospects and leads to be fed onto Salesforce, SugarCRM, or Pipedrive.
- Generated unit tests on existing Django applications and fixed logical processes, scalability, and authorization issues.
Software Development Engineer
FPT Software
- Worked with some of the pioneering projects from the Vietnam HQ, namely KPMG and KNH.
- Built web applications that use NoSQL and relational-database systems like Cassandra, Redis, MS SQL Server, and PostgreSQL.
- Ventured in creating the web application of the proof-of-concept Internet of Things system application that would lure client companies to work with us.
Experience
Lineup.ai Revamp
https://www.lineup.ai/I created the dataflow-centric deployment pipeline using Prefect CLI, GitHub Actions, and ECR. Moreover, I standardized the EKS cluster in Terraform code for the Prefect flows, leveraging the Dask distributed and Karpenter features to harness the full capability of autoscaled workflows automation, lowering the total cost of ownership (TCO) by 60%.
Intelyse InSight Revamp
https://intelyse.com/I created the CI/CD pipeline using GitHub Actions and built the entire autoscaled, highly-available infrastructure within AWS using Terraform. With the added cloud-native security, visibility, and external monitoring tools, I also incorporated Cloud Map and HAProxy internal load balancer within the ECS clusters to enable automatic service discovery, allowing low latency and high availability.
Therago | Formerly Clinigo
Think Calendly but with search features for remote practitioners in Australia. I implemented the integration of HTML mockups with the actual implementation in Django REST Framework and React, hosted on AWS Lambda and S3.
Project Bifrost
I led its infrastructural acquisition from a US-based outsourcing company in Greenville, South Carolina. By upgrading its Python dependencies and remediating its application-level common vulnerabilities and exposures (CVEs), I abolished LambCI and streamlined its serverless deployment via GitHub Actions.
Rentahaus | Currently part of InventoryVolt
Using the provided HTML mockups, I implemented Angular and Eve integration like Flask-based API meta-framework and hosted it with AWS Lambda and S3.
