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.

My contributions to Weave GitOps (React/Golang Kubernetes dashboard project):

My latest fullstack code sample: https://github.com/opudrovs/react-api-data-sample/
Frontend: React/Next.js/TypeScript/Mantine UI/Tailwind CSS Backend: Node.js/Express/TypeScript/PostgreSQL/Supabase Auth
For this sample, I researched the most popular modern UI frameworks and picked Mantine and Tailwind CSS as the winners. It was an interesting engineering challenge to make Mantine UI and Tailwind CSS work well together in a Next.js app. Additionally, the whole project is dockerized, allowing you to spin up the frontend, backend, and a PostgreSQL database seeded with test data with a single command. (Please see the Readme file for instructions on how to run the project and for a video demo.)

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 Concrete examples:* 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.

About Me: I’m Karan Krishnani, an independent software consultant with over 15 years of experience in full-stack development, cloud solutions, and AI integrations. I’m currently looking for projects as a fractional embedded team member (10–20 hours/week). My background includes building scalable solutions for industries like healthcare, government, and financial services.
I have 10 years of experience in Fin-Tech and over 14 years combined in Journalism, TV and Media, Health, Science, and more. I've worked for clients like JPMorgan Chase, Santander Bank, Rob Walling, Trello, Peter Diamandis, Syncthing, SimplyCredit and others.
I'm experienced in Vue.js, Django, Phoenix framework, Quasar to name a few. Pick up new tech easily and like working on complex products. Old case studies are on my website: https://gilli.is. However, most work from recent years has been buried behind NDAs. I can provide the following for you:
- Design — Whether you need a design from scratch, a redesign, or you're having issues with a small part of your product, I can design it.
- Front-end Development — I can build the design into a pixel perfect product. This is rare among us designers and has proven to be extremely powerful for the result since there is less wasted effort.
- Analysis — Your users, know everything that's wrong with your product but have difficulty communicating it. Often it comes out in anger and frustration. That's where my usability analysis comes in. I'll review your app from an outsider and expert point of view, and give you actionable feedback.
- Free advice — You might not be sure if I am the right fit, and I very well might not be. I can help you figure out the best direction to go for free.
I take my work very seriously and put a lot of work into excellent communication, proper planning, and, last but not least, properly understanding your product so that we can produce great results.

Candidates will only be considered if they have a history of working in the Ruby implementations of the GraphQL ecosystem.

Looking to work for or with anyone in construction tech or any service business that deploys skilled resources to multiple locations on an ongoing basis(i.e projects not gig/delivery work).
Tech skills include website development, customization, and deployment: JavaScript, react, express, nextjs, netlify, webflow, Wordpress, git.
I have experience implementing sales funnels from landing page to boots on the ground service work(that is, I built sales pages that captured cold leads, made the sales and then coordinated the work). Ive also implemented project management software, and built custom in-house estimation, management, and scheduling tools to fulfill gaps in what off-the-shelf commercial software can do.

SEEKING WORK - Data scientist, remote worldwide, email in profile.
I'm a data scientist and I've been absolutely slaughtered by this recession. I lost a big project in July and haven't picked anything up since. Everything is "on hold", "Taking it in house". I hope things will start moving again.
I love avant garde problems, and have a pretty unique toolset (LLMs+KB, OR+ML, etc). I've worked with names you know in automotive, tech, and other spaces.
I've worked on projects including large language models, knowledge extraction, automotive part failure prediction, translation, maintenance optimization, automated sports highlights, and more. I've also done some more interesting work including vehicle route planning in constrained environments.
Get in touch. Even if you're unsure, get in touch. Referals welcome. Email in profile.
I help companies with cloud infrastructure (AWS, GCP), security, and compliance needs, offering long-term monthly subscription packages tailored for startups. With 10+ years of experience managing cloud infrastructure, I have also led multiple successful SOC 2 and HIPAA audits.

Full-stack web developer with 5+ years of experience. Specialize in developing comprehensive UI interfaces for platforms, fintech applications, and user management systems.

Experienced in greenfield projects, brownfield projects, rewrites, and legacy systems, working both independently and as part of collaborative teams to deliver high-quality solutions.
Looking for companies in the B2B/D2C e-commerce sector in niche markets.
I have more than 10 years of experience in the software and marketing aspects of B2B/B2C e-commerce (Europe & US). For the past 2 years, I took a deep dive into D2C as a Technical Co-Founder of a fragrance-related brand (https://yuma.gr), successfully positioning us in the premium market at the lowest cost possible, by developing the e-commerce and ERP platform in-house.
I can handle all aspects of e-commerce with a focus on growth. Examples include:
- Extensive Google & Facebook Ads automation at scale via their APIs
- Distributed bots for scraping millions of SKUs daily for dynamic pricing
- Deep & proven knowledge of e-commerce & ERP architecture & development
- Complex and custom-made solutions (e.g., in-house developed Klaviyo alternative)
- Creative approaches to streamlining internal operations
- Frontend performance & SEO micro-optimization
- Landing page optimization for conversions
I prefer long-term commitments and typically work on projects for 6 months to 1 year, as I treat each project as my own. Having developed my D2C brand to a technical level that now requires only maintenance and marketing, my schedule has become more flexible. I'm ready to help companies in different markets while expanding my skills and knowledge.

I work with clients ranging from start-ups to established corporations, helping to consult and manufacture prototypes. I excel in helping other engineers who lack manufacturing experience design a product which will be manufacturable, along with discovering ways to lower costs and improve the product goal.
With my own in-house CNC manufacturing capabilities (milling, turning, plasma cutting) using state of the art industrial equipment, I am able to easily expedite prototypes for my clients.
I am well rounded with skills outside of mechanical engineering including experience in automation and control systems, robotics, software development, and more.
Current projects include developing engine dynamometer systems, including the required control systems and mechanical assemblies to accurately test racing engines: https://www.precisiondynotech.com/

Unicorn. I do branding [1], design, and full-stack JavaScript development. I built the Joystick JavaScript framework (full-stack [2]) and Push deployment service [3]. Recently shipped Parrot [4]. Currently preparing a CSS framework for SaaS apps for release [5].
Though I prefer my own tools to move fastest, I'm competent with and adaptable to any/all JavaScript + Node.js frameworks and tools (e.g., Next.js, Svelte, Vue, etc). Can also handle TypeScript if need be.
Looking to work with startups, entrepreneurs, and small teams (or VCs who need a sharp shooter who can deliver) who need help shipping product and features that work from day one, ASAP.
17+ years of experience running a small business/shipping software, so I don't need to be babysat—just set loose with a clear idea of what needs to be built and open lines of communication if/when I have questions.
Average time to brand, design, and ship a full-stack app is 3-6 months but I can move faster if you're willing/able to delegate 100%.
