# Tomislav Markovski

> Personal site and portfolio of Tomislav Markovski, Senior Cloud Architect & Consultant based in Miami, Florida. He builds practical generative AI applications and the systems around them — durable orchestration, distributed services, and Azure cloud infrastructure — with a long background in decentralized identity and applied cryptography.

In his own words: "Based in Miami. I build practical generative AI applications, especially for document processing, search, and complex business workflows. I spend a lot of time on the systems around the models — durable orchestration, distributed services, and cloud infrastructure, mostly on Azure. I also have years of experience building identity platforms and working with applied cryptography, open standards, and secure systems."

## Projects

- [Ziva](https://ziva.fit): Nutrition tracking through conversation. Describe a meal in Claude or ChatGPT and Ziva resolves it to USDA food data with a detailed nutrient breakdown. (Creator · Solo developer — SvelteKit, Python, .NET, MCP, Azure, Cosmos DB, GPT-4o)
- [Longhand](https://trylonghand.com): Neural handwriting synthesis for web and mobile. Longhand turns typed text into expressive, human-looking handwriting. (Creator — Neural synthesis, Web, Mobile, Handwriting generation; source: https://github.com/tmarkovski/longhand)
- [Argus · DBOS workflow viewer](https://github.com/tmarkovski/dbos-argus): A self-hosted, read-only dashboard for understanding durable workflows in DBOS Transact applications. Point it at Postgres or SQLite and inspect workflow state without app-side wiring. (Author — Python, FastAPI, DBOS, PostgreSQL, SQLite, Docker; live: https://dbos-argus.purplesand-f5d0196c.eastus2.azurecontainerapps.io)
- [Very Good Wallet](https://verygoodwallet.com): A digital credential wallet where your passkey is the wallet — no seed phrase, no server-side custody; the entire key hierarchy is derived from the passkey PRF. The live demo pairs the wallet with a DMV issuer and two age-checking verifiers, with a guided tour up the privacy ladder: OID4VCI issuance, OID4VP presentation, BBS selective disclosure, and in-browser zero-knowledge predicate proofs. (Creator · Solo developer — Passkeys, WebAuthn PRF, Verifiable Credentials, OID4VCI/OID4VP, BBS Signatures, Noir ZK proofs, Cloudflare Workers; case study: https://verygoodwallet.com/writeup/; source: https://github.com/tmarkovski/verygoodwallet)

## Open source

- [Hyperledger Aries .NET SDK](https://github.com/hyperledger/aries-framework-dotnet): A .NET framework for decentralized identity applications and standards-based credential exchange. (Author · Maintainer — .NET, Hyperledger Aries, Verifiable Credentials, Decentralized identity)
- [did-key.rs](https://github.com/decentralized-identity/did-key.rs): A Rust implementation of the did:key method for creating and resolving identifiers derived from cryptographic key material. (Author · DIF contributor — Rust, Cryptography, DIDs, Decentralized Identity Foundation)
- [BBS Signatures](https://github.com/trinsic-id/bbs): A Rust implementation of the BBS signature scheme, including selective disclosure and zero-knowledge proof capabilities. (Author · IETF contributor — Rust, Cryptography, BBS, Zero-knowledge proofs, IETF)
