============================================================

Robbert, front end developer with 7+ years experience. Focus on interactive interfaces in React.

If you need someone to build a dashboard, interactive widget, or beautiful animations with great UX, look no further.

I’ve got experience building complex interfaces with React, using a variety of tech stacks: Next.js, Gatsby, Redux, Material UI, Tailwind, Framer Motion, Radix, and more.

Non-tech qualities: Clear and open communicator, reliable, and able to not just implement but also design interfaces with business needs in mind.

Recent projects (all for US companies) include: Frontend for large-scale video assets management app, frontend of marketplace app, UI for dev tool desktop app.

Looking for: Clearly defined projects (Brand New Portfolio: https://www.studiokoro.com Email: robbert@studiokoro.com

I am a backend expert, having built and maintained highly available systems for several companies over the last 9 years, in addition to over 20 total years of software development experience. I learn new things extremely quickly.

You will like working with me because I:

     * hold your goals as my priorities
     * communicate verbosely yet synthesize well
     * my rates are reasonable in exchange for the value I deliver
     * I guarantee I will get the job done

* built the streaming data architecture for realtime game player information and game stats for one of the top 3 US sports leagues (can’t name drop!) using Redpanda/Kafka on Azure+Terraform, and implemented its developer portal using Gravitee to provide first class streaming API support and monetization.

* Implemented a vector DB for one of the leading AI image hallucination platforms (millions of users) to provide an image similarity service.

* replatformed dozens of jobs to AWS Lambda for a startup hedge fund, vastly improving QoS and maintenance cost. Line 1 to platform-in-prod time 3 months.

* built a ~50 node, AWS, Dockerized, Terraform-deployed distributed system to provide realtime, transformed trade data from crypto exchanges to a Kafka pipeline and data lake (fodder for an analytics platform). Met 5000msec SLA across arbitrarily many exchanges and ticker symbols. Blue-green deployment for complete CICD safety. Cloudwatch metrics proved SLA was met and provided general system oversight.

* built a framework to collapse dozens of singleton ETL programs into one config-driven, simple C# application performing the same functionality at ~80% reduction in maintenance cost year over year.

One of the services I offer is a one stop shop for MVP and prototype development. I do rough UI and UX design, small scale frontend, backend, data infrastructure, API design, and devops. I do whatever it takes to take your idea from the drawing board to a functioning prototype.

Another service I offer is updating janky startup prototypes to modern standards and practices. I love maintaining and improving legacy code. It's like restoring old furniture.
