Senior Data Engineer

 I' ve spent 10 years building data infrastructure and trading systems in blockchain. 

At Injective Foundation, I built the entire data pipeline - 46,000 lines of Python processing $84M+ in trading operations. Real-time chain analytics, treasury monitoring, distributed systems on GCP/Docker/Airflow. Everything production-scale. Before that, 

I traded at Nexxus Group (crypto hedge fund) where I wrote algorithms in C++ and Python that delivered 461% returns. 

I also built a delta-neutral DeFi product and consulted on tokenomics for Ribus (Brazil' s first real estate token). Right now I run my own market making on Kraken - Monero, Ethereum, Paxos Gold - pulling 53% APR using a Uniswap V3 model adapted for orderbooks. Deployed via Google Cloud Run. 
I' ve been actively trading DeFi since 2018: funding rate arbitrage, liquidity pools, cross-protocol yield strategies. What separates me from most candidates: I understand both sides. 

I' ve built the infrastructure for trading, data AND I trade with my own capital. 
I know what breaks in production because I' ve fixed it. I know execution challenges because I deal with them daily. 

Anything on DeFi, Trading, Tokenomics, Liquidity, Lending, Game Theory, Backtesting, Data Science, Data Engineering and Blockchain will for sure lead to a great chat. 

I’m confident I fit the top applicants and firmly believe that we can schedule a call to deep dive! 

Thank you!

Over the course of 5 years, I dedicated my time to building these sophisticated algorithms that operate with my personal capital. I continuously refine and optimize the algorithms, leveraging my skills to navigate the dynamic landscape of financial markets Such project involves ETL data from exchanges API to a database. Then analyze the data through proprietary pricing models with python to identify patterns and outliers. After all, apply the predictive models to present data in order to exploit market inefficiencies.
