Golang Developer

● Preparing binaries for new releases of Gaia, Juno and Osmosis networks ● Working currently on upgrading Firehose to create a pull request for upstream cometbft repository

● Implementing keyresharing for Multi-Party Threshold Signature Scheme (TSS) in cosmos-sdk module ● Debugging and improving performance of p2p network ● Deploying test environment - providing configuration and preparing liquidity pools ● Integrating new chains - adding manually new Ethereum chains (Optimism, Polygon zkevm, Binance) and automated this process. Removed chain configuration from code and reading it from file and on-chain data. ● Building and deploying transaction bot with notifications about errors on slack channel. Transaction bot dashboard had a view of running jobs with logs and simple form to trigger a new job with custom configuration for wallets, networks or amount for transaction. Test environment required to have running dev blockchain with non-empty liquidity pools with tokens for gas and prepared wallets with funds on 10 different chains. ● Research and initialization of integrating bitcoin to Kima chain. Created a new type of transaction

● Indexing transactions and calculating rewards for multiple blockchains via service workers. ● Developed cosmos-sdk integration with TheGraph infrastructure. Enabled blockchain data processing like, fetching and filtering. Unblocked integration of Graph with multiple different downstream chains (ATOM, Osmosis, Juno). ● Unblocked data digestion of blockchain data by creating Protobuf definitions, which later were used for defining specific extraction logic. This logic could exist as multiple languages. In addition, implementing decoding functionality for WASM based blockchains. ● Documenting examples for developers to process blockchain data.

● Unblocked new deployment processes for SpaceLift (IaaS) by creating new GraphQL API Endpoints based on customer requirements. ● Integrated SpaceLift actions (which is an IaaS) to slack channel action commands. Required developing new endpoints and integrating with SlackAPI to create custom channel action. Afterward, lead testing and launching of features. Required AWS SQS Integration.

Development of multimedia services and client devices Software development and OTT solutions department ● Wrote more than 100 backend unit tests in Go improving service stability ● REST API development for Orange TVGO microservices, creating new endpoints and improving existing to add new features to client applications (iOS, android and web) ● Improving efficiency of fetching EPG algorithm which was triggered periodically to apply changes from TV guide ● Building admin service - frontend (react) and backend (go) to manage content present on site, ex. change order of VOD categories, uploading new photos to slider
