Ask HN: Freelancer? Seeking freelancer? (August 2023)

Amen. I thought they forgot a 0.

SEEKING WORK | Canada | Remote

I have a PhD in operations research---essentially, I solve optimization problems. You can give me a real-world problem and I can translate it into a mathematical model that can be solved (often optimally) via integer programming, constraint programming, or other methods.

I'm currently working on a column generation-based daily fantasy sports (DFS) solver as a personal project. Taking as input the predictions/requirements of the user, this solver can generate optimal lineups for multi-entry tourneys. It is, as far as I'm aware, the only DFS solver that can generate provably optimal sets of lineups for multi-entry DFS tourneys.

SEEKING WORK - Contract, Remote, based in NYC area, backend engineer

I am a backend expert, having built and maintained highly available systems for several companies over the last 7 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 information 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.

* 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.
