I'm solidity developer.
I started my way in the IT field as a freelancer and worked on the Laravel
framework (PHP framework). In the beginning, everything seemed like magic
to me, but after I learned how to do magic myself, I just fell in love with it.
Further, I entered the magistracy in Riga, Latvia. I started looking for local
companies and found Scandiweb, which is developing e-commerce solutions.
After more than a year with this company, I realized that I wanted to do
something new and have potential in the future. Thus, I became part of the
cohesive Сrypton team. 
At the moment, I am already developing solutions for NFT marketplaces, token
staking, bridging between blockchain networks. Moreover, knowledge of the
use of hardhat and truffle development environments, as well as knowledge of
writing tests, tasking, and deploying scripts for contracts, helps to facilitate the
development and communication of the front-end/back-end with smart
contracts.
One of my great achievements that I can be proud of is the ease of learning
new technologies. Of course, the study time varies from the degree of
development of the community of this technology and/or official
documentation.
At the moment, I devote my free hours to studying materials related to
blockchain and new solutions for them. But I'm already thinking about joining
the gym.

My biggest project so far is Defi Hedge Bot - a telegram bot
that helps crypto yield farmers mitigate risks by using short perpetual futures on the FTX exchange. It is
built using telebot, MongoDB database, and open-source FTX exchange API. It was released on the Hetzner
VPS.
With more than 10 years of experience in finance/economics and my passion for technology, I started my
journey in crypto back in 2017 and entirely focused on it beginning in 2021.

I always wanted to explore the tech side of crypto, so I used my Python to gather and interpret data, automate
everyday tasks and get an advantage in the market. Switching to Solidity gives me the ability to read
contracts and understand what is really going on there. I have focused on smart-contract auditing, as I am
sure it is the fastest path to master my skills, I am reading and analyzing hacks, and audit reports and I
participate in code4arena competitions.
I do not want to waste my life working on a project that no one really needs. I want to do something useful, that I may be proud of.

I want to be part of a friendly team united by one common goal.

Roci.fi
RociFi protocol is a DeFi primitive for permissionless under-collateralized lending. Built on Ethereum, RociFi will launch initially on Polygon. RociFi is reinventing credit to be more inclusive while increasing capital efficiency in DeFi by leveraging on-chain behavior and reputation to issue under-collateralized loans. As the protocol grows in adoption, it will function similarly to a Layer 1 whereby DeFi and TradFi firms can build new capital markets services atop RociFi, thus creating a decentralized credit economy.
