Full stack software engineer mastering: NodeJS, MySQL, Redis, MongoDB, AWS services for backend and HTML5, CSS3 and Javascript ( reactjs ). I am able to build complex architectures with NodeJS, RestAPI(Express, Koa, Fastify) and GraphQL, MySQL, MongoDB, PostgreSQL, Redis, AWS Services like S3, Cloudfront, SQS, Lambda, API Gateway, Elasticsearch etc. I am very familiar using tools like: Typescript, BabelJS, Webpack, Grunt, Gulp. I can implement various services using serverless architecture with API Gateway, S3, Lambda. Strong experience in optimising MySQL queries and structures.

I am a seasoned Postgres database architect specializing in architecture for data-driven processes such as ERP's, CRM's, Fintech, etc. Chances are you are not using your database nearly to the capacity it can serve you and I can fix that. I am a systems design engineer first and foremost. Writing queries (with supreme excellence) is an art form, but still only secondary to the most important element: architecture which is where I excel the most. Beyond that, I'd say my "traditional" Postgres skills (listed below) are above average as well. Fair warning: I consider databases to be first-class citizens. I have developed a very successful workflow for producing good results. It begins with patiently asking questions to understand all of the contextual needs and then going about solving them in an iterative process with lots of two-way communication along the way. I utilize a loose framework and building workflow that makes it inherently easy to change and adapt as needed. This is important because good design is never achieved in the first iteration, so making architecture amenable means it can always get better. While I can obviously help with smaller projects, its the bigger challenges such as overhauls and ground-up projects that suit me best. I excel in complex cases and situations involving higher maths, algorithms and fuzzy logic. Traditional Skills: - ETL, Migrations, Imports - Advanced Functions/Procedures - Advanced/Complicated Query writing and optimization - Custom triggers, aggregates, types, etc. - User/role/security management - Indexing - Config tuning

I am passionate about database design and visualisations in a way that it speaks for themselves. I have been helping companies create data representation, optimization and visualisation solutions by understanding business needs, not only how to make charts. I realize that data is often complicated, but it doesn't have to look that way if we design it properly from scratch. I combine my experience in data analysis, visualization, and design with the awesome capacities of Power BI to make data understandable and beautiful. My Data Stories are crafted to communicate information in the clearest, most efficient manner. I believe that the more effectively the data is presented, the more easily the information is consumed. Power BI has fantastic capabilities that allow information to be presented in an appealing, clean style, yet still contain all of its intrinsic depth and complexity. From engineering the data to the finished dashboard, I make the complex approachable. I am experienced, professional, and I have a passion for what I do. I am pleased to offer complimentary consultations online or by phone. I can also provide you with a sample visualization of your data for a nominal fee. I look forward to learning about your project and I appreciate this opportunity. I’m able to: Build Power BI report using DAX and Power Query Translate your business problem into compelling storytelling via dashboard Calculating all your metrics for your business Connecting all data sources (Database, Azure, AWS, Google Cloud, API, flat files etc) into Power BI and also build custom API connector Setting up a cloud platform for your BI reports in Azure & AWS (Refer to my other gigs!)
