Confidential Blockchain Specialist for Startup

@rahuliitm69

Hi there, My Blockchain developer is immediately available to join your confidential short-term project and contribute expertise in privacy-focused cryptocurrency solutions. The developer will be working on Solidity and Hyperledger, implementing private transaction mechanisms, secure wallet/API integrations, and other blockchain-related features. They have strong experience in privacy coins and EVM-compatible development. You will get a highly skilled, discreet, and reliable expert who can work remotely or in hybrid mode, delivering quality results while strictly adhering to NDA requirements. Looking forward to discussing the project details and starting immediately to contribute to your initiative. Thanks, Rahul

Hello there, We have around 8 years of rich experience in backend systems architecture, API integration, and secure transaction processing pipelines. Your focus on Monero's privacy layer — ring signatures, stealth addresses, and RingCT — tells me this isn't a generic crypto project; you need someone who understands the cryptographic primitives underneath, not just wallet API calls. **Architecture Overview** The system would break into three layers: a Monero daemon layer (monerod + monero-wallet-rpc) handling chain sync and transaction construction, a middleware API service managing business logic and payment gateway orchestration, and an encrypted data store for transaction metadata. The wallet-rpc interface handles ring signature composition and stealth address generation natively, so the middleware never touches raw keys — critical for the privacy guarantees you're after. All inter-service communication runs over TLS with mTLS between the daemon and API layer. **Technology Choices** Python with FastAPI for the middleware — it's async-native, which matters when you're polling monerod for transaction confirmations that can take 2+ minutes per block. For the payment gateway integration layer, we'd build against monero-wallet-rpc's JSON-RPC interface directly rather than wrapping a third-party SDK, because most Monero payment libraries abstract away the privacy controls you specifically need (like manual ring size configuration and subaddress management). PostgreSQL with column-level encryption for any metadata that touches disk. Docker containers with isolated networking so the daemon's P2P port exposure is tightly controlled. **Relevant Work** We've built enterprise integration platforms for Fair Trade certification — end-to-end supply chain traceability with Python, Django, PostgreSQL, and API integration where data privacy and auditability were non-negotiable requirements. That same discipline around secure data handling and API-layer isolation maps directly to privacy coin transaction processing. **Risk Mitigation** The biggest risk in Monero integration is transaction relay failures and view-key exposure during payment verification. We'd implement a dedicated view-only wallet instance for payment confirmation, fully separated from the spending wallet — so even if the verification layer is compromised, funds stay safe. Happy to share a high-level architecture diagram. We'd structure this in three phases: Phase 1 (weeks 1-3) — daemon setup, wallet-rpc integration, core transaction handling. Phase 2 (weeks 4-6) — payment gateway API and privacy controls. Phase 3 (weeks 7-8) — testing, hardening, and documentation. Weekly video updates plus async communication on Slack or your preferred channel. I'm comfortable signing an NDA before discussing specifics — what's the primary use case driving the payment gateway integration: merchant-facing payments, internal transfers, or something else? Looking forward to hearing from you. Naveen Brainstack Technologies
