# Selby Baidjnath

Senior engineer and founder. I build software systems, and the teams that ship them.

Based in Paramaribo and Miami.

## Building

-   ### [Borderless](https://borderlessnv.com)
    
    Helping companies in Paramaribo go borderless with software built around them.
    
-   ### [Serubii](https://serubii.co)
    
    My engineering consultancy. I do the architecture and the building myself, from AI products to hard migrations.
    

## Selected work

### AugtalCTO of an AI recruiting platform, from first commit to acquisition.

-   Designed the core architecture in TypeScript, Python and React, with quantized models to keep inference fast and affordable.
-   Built the cloud infrastructure and security operations from nothing, on Docker and Kubernetes.
-   Hired and grew the engineering team, and set up integrations with AI platforms, SaaS vendors and API providers.

TypeScript, Python, React, Kubernetes, pgvector

### Plasma SDKsLed teams delivering cryptographic SDKs across five languages and a next-gen web wallet.

-   Led the engineering team porting and redesigning cryptographic SDKs from Scala to Java, Kotlin, TypeScript, Rust, and Dart, maintaining strict cross-platform parity and security standards.
-   Led the development and architectural overhaul of the next-generation Flutter web wallet.
-   Coordinated work and sprint delivery across distributed internal teams and external contractors.

Dart, Flutter, TypeScript, Rust, Kotlin, Scala

### IT PartnerMigrated mission-critical shipping software across European ports with zero downtime.

-   Led the migration of large-scale legacy C# Windows Mobile shipping & logistics applications used by field teams across major European ports to a modern, cross-platform Flutter stack.
-   Integrated the platform with modern maritime tracking tools, hardware barcode scanners, and enterprise backends without disrupting active port operations.
-   Modernized CI/CD pipelines in Azure and Firebase, transforming manual deployments into automated, resilient releases.

## Toolbox

In my experience as a software engineer I have worked across many domains and languages, a full list would do us a disservice. Today, I'm capable of working across multifunctional teams, distributed architectures, AI native workflows, and high scale data systems. I pick the technology that fits the problem the best and ship it end to end.
