Thank you very much for your interest! We will be happy to assist you in carrying out the required technical implementations.
Experienced Solana Blockchain Developer and Tech Lead. I develop blockchain applications for Solana and help my clients with the full implementation of their operational processes, including cloud, databases, web, and mobile.
I am particularly proficient in overall project architecture, cloud design, and programming for servers and Postgres or Firebase databases. I typically use Node, Rust, SQL, Python, and Linux Ubuntu services, as well as Google Cloud and AWS, with services like BigQuery, Lambda, Aurora, SNS, SQS, etc.
I am a highly skilled Solana developer, with two commercial projects already completed. I can implement complete on-chain solutions, with or without Anchor, fully custom or by leveraging existing programs and services, such as Metaplex, Helius, etc., including on-chain tools like CPI, ALT, fuzzing, Nonce, and Partials, etc. If you don't know what these tools are and are curious, feel free to contact me!
Additionally, I develop various complete professional mobile applications, in React Native and Swift/Kotlin, for iOS/Android, and more generally internal applications for medium and large companies.
Furthermore, I have over 200 projects completed for international clients across various sectors and technologies.
