EXPERIENCE

TRUSTECH CORPS, SAINT PAUL, MN 07/2023 to present

AWS Solutions Architect

Technical Skills

Designed built AWS Secure, High Availability, Fault tolerance, High Performance, Resilience & Efficient -Cost Optimized Infrastructure/Architectures.

Used Splunk for compliance management, application management, monitoring IT Infrastructure management and industrial data analytics, helping organizations improve performance and reduce risks.

The Appian Platform (SaaS) for AI-powered process automation. The fastest way to design, automate and optimize end to end business processes

Event Driven Architecture & Serverless Computing, Saas sources for data collection using Amazon App-Flow., Lambda function

Secured Multi-Tier Architecture that is integrated with In-Depth-Defense Security.

AWS Native-Architecture, Data Analytics, Redshift, Quick-Sight, S3, Glue, Athena, Glue Catalog. Aws Control Tower, Landing Zone, Organization, VPC

AWS Services: Lambda Functions, Step Functions, Event Bridge, Cloud Watch, SNS, SQS, ETL, Relational & Non-Relational Databases

Micro Services Integration, Amazon Event-Bridge for scheduling events that invoke lambda function.

Used Aws Cost Explorer, CUR for cost management.

Used Price list Service API & Price list API for checking prices of Services & products

SNS. For Sending “Alerts” to clients when Aws prices change.

Used AWS App-Flow to securely transfer data between (Saas) app (Salesforce, Slack) to AWS destinations: - Amazon RedShift, S3 Snowflake & Neptune for building fraud detection app.

BRIGHT MLS: Senior Data Engineer 05/2022-06/2023

Used Aws Glue Data-Brew for cleaning and normalizing data for analytics & ML

Introduced AWS Quick-Sight, (BI) Service replaced Sisense platform. Saved company’s monthly expenses by40%.

Moved data sets from Amazon S3 to Redshift, then to AWS Quick-Sight for visualization, increased product value by 25% from the previous platform.

Used App-flow to sync data from different sources for analytics and ML

Used Aws query editor version 2, a serverless web-based SQL client application to run queries on Amazon RedShift. It enhanced visualization of my results on charts as well as collaboration, share queries with team members.

Change the data format from csv to parquet when writing to S3. The company saved up to 12% on monthly expenses.

Used AWS Glue ETL (Structured, semi structured and unstructured) data from different sources into AWS Redshift. Moved data automatically to Amazon S3, used Athena to run SQL query the data, Used AWS Glue/crawler to create Glue tables in Glue Data Catalog. - Implemented Amazon Redshift Spectrum to run queries on the data. Used Crawler to create and manage AWS Glue Tables Schema, & partitioned AWS Glue tables.

Used AWS ETL to simplify data integration, automate schema discovering and scale data processing using Apache Spark to prepare data for analytics in data lakes &warehouses.

Data Lineage & its importance. Ex. Compliance & Regulations.

Implemented ETL to automate task like schema discovering, provision of a Central Data Catalog made data preparation faster, easier and cheaper at any scale by 23%.

Collaborated closely with data scientists, analysts and business stakeholders to understand data needs and deliver data solutions aligned with business goals.

Used Slack, Scrum, Sprint and Agile to get project goals achieve 120% faster.
