I help startups with the UX/UI and web design of their products. This includes web apps, websites, landing pages, copywriting, and I can assist with frontend development where needed. My background of launching my own products and being a full stack developer helps me create practical designs that balance usability, aesthetics, development effort, and performance. I work to fixed price quotes for self-contained projects.

The best live example of my work is Checkbot (https://checkbot.io/), a browser extension that tests websites for SEO/speed/security problems. The entire project is my own work including coding the extension itself, UX/UI design, website design (the homepage is optimised to load in 0.7 seconds, 0.3MB data transferred), marketing, website copy, and website articles on web best practices.

Available for remote work worldwide, very flexible across time zones. Looking for permanent or contract positions. Hi! I’m Olga, an experienced software engineer looking for frontend or fullstack projects.

I have experience building greenfield projects and complex features that “just work,” as well as diving into complex legacy codebases, fixing “unfixable” bugs, and performing major refactoring.

In addition to React/Next.js and Node/Express.js development, I also have experience with cloud-native workflows (Golang + Kubernetes), OpenAI API integration and agentic workflows, native iOS development, and game development. Thanks to my multi-platform experience, I can help you port large products across different platforms.

Hi there! I'm Nitin, a software engineer with a passion for AI/ML, computer vision, and automotive software.

I’ve spent some time at Bosch developing real-time ADAS applications and optimizing perception pipelines, and I'm now deep into research at NC State—exploring information bottlenecks in deep learning and contributing to open-source projects like SGLang. I've also led projects in robotic navigation using Visual SLAM and ROS, fueling my interest in autonomous systems. Lately, I've been diving into AI agents and exploring innovative applications across different domains.

I'm eager to collaborate on challenging projects in robotics, intelligent systems, or any cutting-edge tech. If you're working on something exciting in these areas, let's connect!

While I'm familiar with various technologies, my passion lies in programming with Rust. Whether it's backend development, blockchain, compilers, DevOps, embedded systems or mobile applications, I am totally onboard as long as there is a little bit of Rust involved.

For more information, take a look at my CV (https://c410-f3r.github.io/curriculum.pdf) or my GitHub account (https://github.com/c410-f3r).

I am a backend expert, having built and maintained highly available systems for several companies over the last 10 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 tracking information (all games, 50ms SLA) 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. Also built, deployed and maintained their ask-a-question-get-a-true-answer AI bot to expose 20+ years of stats to natural language fan questions!

* 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.
