# Hi, I'm Flowdesk Founder 👋

### Senior Full‑Stack Web & Mobile Engineer · Cryptography specialist (ex‑FlowCrypt, iOS + Chrome Extension) · AI enthusiast · Founder of [Flowdesk](https://github.com/Flowdesktech)

**I build full‑stack web apps, native & hybrid mobile apps, end‑to‑end encrypted systems, and AI‑powered products — end to end, from the first wireframe to the App Store release and the production backend that keeps it running. Specialist in cryptography and privacy, with four years shipping production OpenPGP email at [FlowCrypt](https://flowcrypt.com) (iOS + Chrome Extension, 2022–2026). Remote, worldwide.**

## About Me

I'm a **senior full‑stack web and mobile engineer** who ships end to end — from the first wireframe to the App Store release and the backend that keeps it running. My specialty is **cryptography and privacy‑first applications**: I spent four years at [**FlowCrypt**](https://flowcrypt.com) (2022–2026) as a senior engineer on their **iOS app** and **Chrome / browser extension**, shipping OpenPGP key management, passphrase‑protected keychains, Gmail/IMAP integration, and the E2EE flows users touch every day, to a production install base of privacy‑sensitive teams and regulated industries. Today I run [**Flowdesk**](https://github.com/Flowdesktech), a small remote studio building products where trust is load‑bearing.

- 🌐 **Full‑stack web** — React, Next.js, TypeScript, Node.js, Python, Firebase, Postgres. Frontend, backend, infrastructure, CI/CD — I ship whatever the product needs.
- 📱 **Mobile specialist** — Native iOS (Swift, SwiftUI) and Android (Kotlin, Jetpack Compose), plus hybrid apps with React Native, Expo, and Flutter. Real App Store and Google Play release experience, including four years at FlowCrypt.
- 🔐 **Cryptography & privacy** — OpenPGP (at FlowCrypt), AES‑GCM, Argon2id, drand/tlock identity‑based encryption, Web Crypto API, and zero‑knowledge server boundaries enforced by auditable rules. See [**Flowvault**](https://github.com/Flowdesktech/flowvault) for a public reference.
- 🧩 **Browser extension developer** — Chrome / Edge / Firefox extensions, including four years on a security‑critical E2EE extension used against real threat models.
- 🤖 **AI enthusiast & builder** — LLM orchestration, autonomous agents, RAG, evals, and automation pipelines with OpenAI, Anthropic Claude, and open‑source models. I ship AI features into real products, not demos.
- ⚡ **AI‑augmented workflow** — I use AI aggressively in the parts of engineering where it actually makes people faster: boilerplate and scaffolding, exhaustive test generation, large‑scale typed refactors, codebase exploration, and first‑pass code review. Client budgets get spent on the 20% of the code that actually needs human judgment — API design, cryptography choices, UX trade‑offs, and the gnarly edge cases — not on typing out the other 80%.
- 🌍 **100% remote** — async‑first, across time zones.
- 🧑‍💻 **Open source** — I maintain [**Flowvault**](https://github.com/Flowdesktech/flowvault), [**Firestudio**](https://github.com/Flowdesktech/firestudio), [**Snapboard**](https://github.com/Flowdesktech/Snapboard), and more under [@Flowdesktech](https://github.com/Flowdesktech).

> Currently shipping **Flowvault** — a zero‑knowledge notepad with hidden‑volume plausible deniability, drand‑backed time‑locked notes, and a Bring‑Your‑Own‑Storage local‑file mode. More privacy and crypto tools landing under [@Flowdesktech](https://github.com/Flowdesktech) soon.

## What I Do

- **Privacy‑first & E2EE web apps** — client‑side cryptography, authenticated encryption, memory‑hard KDFs, and zero‑knowledge server boundaries. The whole stack, reviewable end to end.
- **Crypto & web3 products** — wallets, signing flows, key management, and web3 frontends built on production cryptography, not tutorials.
- **Browser extensions** — Chrome / Edge / Firefox extensions, including security‑critical E2EE flows.
- **Native Mobile Apps** — Swift/SwiftUI iOS and Kotlin/Jetpack Compose Android, from architecture to App Store / Google Play release.
- **Hybrid / Cross‑Platform Apps** — React Native, Expo, and Flutter apps that ship to both stores from one codebase.
- **AI Orchestration & Agents** — Multi‑step LLM workflows, tool‑using agents, RAG systems, and eval harnesses.
- **Full‑Stack Web Apps** — React/Next.js frontends with Firebase, Node.js, or Python backends.
- **Developer Tooling** — GUI clients, CLIs, and desktop utilities (see [Firestudio](https://github.com/Flowdesktech/firestudio), [Snapboard](https://github.com/Flowdesktech/Snapboard)).
- **Technical Leadership** — Architecture reviews, mentorship, and code review for small engineering teams.

## Selected Experience

#### 🔐 [FlowCrypt](https://flowcrypt.com) · **Senior iOS & Chrome Extension Engineer** · *2022 – 2026*

Four years shipping production cryptography at **FlowCrypt**, an OpenPGP email product used by privacy‑sensitive teams and regulated industries. Owned the **iOS app** and the **Chrome / browser extension** end to end — OpenPGP key generation and storage, passphrase‑protected keychains, Gmail / IMAP integration, and the E2EE flows users touch every day — plus review and QA on the Android codebase.

Same engineering bar [Flowvault](https://github.com/Flowdesktech/flowvault) is held to, on a much larger install base.

## How I Work

1. **Discover** — Understand the problem, the user, the threat model, and what success actually looks like.
2. **Prototype** — Ship something clickable fast. Validate direction before scaling.
3. **Build** — Typed, tested, opinionated code, with **AI used aggressively to accelerate the boring parts** — scaffolding, boilerplate, test generation, and mechanical refactors — so that human time is concentrated on architecture, security, and the edge cases that actually matter. Cryptography choices are justified in writing, not copy‑pasted.
4. **Ship** — CI/CD, observability, and predictable releases from day one.
5. **Iterate** — Tight feedback loops with stakeholders and real users.

## Hire Me

I take on a limited number of contracts each quarter. If you need:

- 🔐 **A privacy‑first or E2EE product built** — zero‑knowledge web apps, encrypted messaging / storage / sharing, client‑side cryptography done right. See [Flowvault](https://github.com/Flowdesktech/flowvault) as a reference.
- 💱 **A crypto wallet or web3 product** — on‑device key custody, signing flows, and production‑grade cryptography (not tutorials).
- 🧩 **A Chrome / browser extension** — including security‑critical E2EE extensions, which I've shipped at scale.
- 📱 **A mobile app built** — native iOS, native Android, or cross‑platform (React Native / Flutter), start‑to‑App‑Store.
- 🤖 **AI features shipped into a product** — orchestration, agents, RAG, evals, and guardrails.
- 🛠️ **A full‑stack product built from zero** — SaaS, internal tools, developer utilities.
- 🧭 **Technical leadership** — architecture reviews, code reviews, team mentorship.

…then let's talk.

- 📧 **Email:** [contact@flowdesk.tech](mailto:contact@flowdesk.tech?subject=Flowdesk%20%E2%80%94%20project%20inquiry)
- 🌐 **Website:** [flowdesk.tech](https://flowdesk.tech)
- 🏢 **Studio / Open source:** [github.com/Flowdesktech](https://github.com/Flowdesktech)

*Typical engagement: 2–12 weeks, discovery through production release and handover.*
