Staff Platform Engineer with 14+ years in distributed systems and cloud infrastructure. I design scalable, resilient, and cost-efficient platforms for data and compute workloads. At Rialtic I built a Go-based pipeline that processed millions of records daily (10× throughput gain) and engineered distributed batch systems on EKS. Before that I founded Shipmile, grew it to a 25-member team and $2M ARR, and built an event-driven backend handling 50k+ daily shipments. Earlier roles include Morgan Stanley (low-latency search over 1TB dataset at <5ms p99) and Meditab (leading a web-stack migration).

Side projects include Conv-SNN in Rust (96.7% accuracy, 2× efficiency vs ANN), a profitable RL-based trading engine, and a CUDA Bitcoin finder achieving 285× speedup. I enjoy building efficient distributed systems, performance profiling, and high-throughput data pipelines. Open to Staff+ roles at startups or scale-ups where infrastructure and system design are critical.

Senior Systems Engineer (14 YoE) applying systems expertise to ML. I don't build models; I build the systems that make ML fast and cheap.

Recent work: - Conv-SNN from scratch in Rust: 96.7% accuracy, 2x efficiency vs ANNs - Profitable RL trading system running since Dec 2020 - 20x GPU speedup using custom CUDA kernels

Currently at Rialtic scaling data pipelines. Seeking Staff-level ML Platform/MLOps roles.

Re:Claude Code weekly rate limits on Wednesday July 30, 2025 @06:06AM (#44732505)
My experience is Claude is better at writing rust than Gemini. Gemini cli gets confused easily. But has good higher level picture. In my use case where Gemini is the architect, it even provides full code changes to claude (does not directly compile most of the time, misses move of structs) and claude makes those changes. It works better for me that way.

Senior Systems Engineer (14 YOE) who loves making software fast. Looking for a challenging, deep-tech IC role.

I like to build things:

* Rust + CUDA: Accelerated a cryptographic key search by >20x over a multi-core CPU baseline.

* Rust Quant Backtester: Built a full-featured backtesting engine from scratch. It's been running my own production strategies for over 3 years.

* Go + AWS: Boosted a critical serverless pipeline's throughput by 10x (Lambda/SQS/DynamoDB) at my day job, unblocking a key client deal.

Ideal roles would be in AI/ML Infrastructure, Quant/HFT, or Core Systems.

DeepSeek: Mathematics

Used to use nomadlist for this. Probably share it on their slack[1] to see it helps them.

In the non oil producing countries, the cost of consumption adds to the fiscial deficit. They even have huge incentive to move away, but the alternative has to be cheaper or open IP. The producers who have a cash cow, have no reason to stop production even if they agree on the environmental issues.

Re:String Deduplication – A new feature in Java 8 Update 20 on Monday September 01, 2014 @03:17PM (#8254292)
Sorry deduplication was a typo. Corrected
Re:String Deduplication – A new feature in Java 8 Update 20 on Monday September 01, 2014 @03:10PM (#8254261)
It was in a typeahead search application built on 20GB of names. These names have common first names and last names which were stored as different strings. With deduplication, string memory was reduced to 20%

Will benchmark that application with +UseStringDeduplication

Re:String Deduplication – A new feature in Java 8 Update 20 on Monday September 01, 2014 @02:48PM (#8254201)
We once maintained a hashmap with key and value as the instance of string to avoid duplication in a search application. Wouldn't that be more beneficial than keeping it in GC if the application uses more strings?

Edit: changed avoid deduplication to avoid duplication
