I'm a senior data scientist with a multidisciplinary engineering background spanning chemicals, renewable energy, and aerospace. Past projects have included abnormal event detection in chemical and energy systems, optimization, and signal processing and classification. I'm ready to take on any problem, in any industry, big or small, in data science, machine learning, forecasting, optimization, statistics, and any sort of modeling.

Reach out if you have questions about how you can extract knowledge from your large pile of industrial data. I'm always excited to learn about a new industry!

Technologies: TypeScript/JavaScript, React, Elixir, Terraform. Can pickup tech (have touched zig, clojure, go, python, ruby).

Most recently, I setup infrastructure (prod/staging) for an AI startup, using terraform, and helping with concurrency issues in python code, etc. For another client, I had replaced there gcp infra located in US, to Mumbai, while also migrating the infra to terraform, with a few min downtime. I often work with TypeScript/JavaScript (e.g working on [Fin Bodhi](https://finbodhi.com/), a personal finance app). And some occasional Elixir. Also interested in visualizations (e.g https://ciju.in/posts/population-census-2011-a-visualization, https://ciju.in/posts/understanding-financial-functions-exce...). I was working as Engineering Manager till few years back. Before that I was running a consulting company (https://activesphere.com/). Comfortable picking up technologies. Would love to be involved in exploration projects, visualizations or complex domains where essence of the problem needs to be understood to build software around it. Or else would prefer projects with active users.

Hi, I'm Jim and I'm a hands-on, full-stack designer, moving products and services from 0 to 1.

My expertise is in complex contexts, technical users and tools. I grew up in a family of programmers, but ended up in design school, so bridging the leading edge of technology and the human experience has always been the default. My research and work has taken me from taking Linux builds from command line to GUI, to designing how we understand cities and their data, to how to design for a p2p internet.

- Consistently delivering inventive, best of class, user-centric solutions that captivate and engage - Expertise in all stages of design, from concept, user research, strategy, wireframes and prototypes to shipping - Natural collaborator, seamlessly integrating with cross-functional teams and stakeholders to inspire strategic thinking and propel organisations forward - Proficient in mixed platforms and emerging technologies with a proven ability to develop ground-breaking products
