To the Solflare team:
|
|
|
|
I've built crypto payment infrastructure from scratch.
|
|
|
|
At Make Post Sell, I designed & shipped hot wallet payment processing for Bitcoin, Litecoin, Dogecoin, & Monero. Real money movement: auto-quoting cart totals, handling blockchain confirmations, managing the reliability challenges that come with irreversible transactions. I understand what it takes to make crypto feel dependable for end users.
|
|
|
|
**Crypto payment integrations in production:**
|
|
|
|
- `blog.makepostsell.com/how-to-accept-monero-payments <https://blog.makepostsell.com/c/91d9119d-9c8e-11f0-9d98-02dfe05770ee/how-to-accept-monero-payments>`_ - Monero integration with automated cash register, risk thresholds, & cold wallet sweeps
|
|
- `unsandbox.com/pricing <https://unsandbox.com/pricing>`_ - Code execution API accepting XMR, DOGE, BTC, LTC with refund address management
|
|
- `git.unturf.com/make_post_sell <https://git.unturf.com/engineering/make-post-sell/make_post_sell>`_ - Open-sourced to public domain
|
|
|
|
**What I bring:**
|
|
|
|
- Direct crypto payment integration experience with hot wallets across 4 chains
|
|
- PostgreSQL, MongoDB, Redis - your exact stack
|
|
- Cloud infrastructure (AWS, GCP, DigitalOcean) & DevOps practices
|
|
- Microservices architecture & queue-based systems
|
|
- SRE expertise scaling systems for millions of users (Remind during COVID lockdowns)
|
|
- 15+ years shipping production systems, 12+ years remote
|
|
|
|
My primary stack is Python, not Node.js. But I've shipped production JavaScript, understand event-driven architectures, & know the distributed systems patterns that matter more than syntax. The blockchain integration & reliability problems are the hard parts. I've already solved those.
