I design and build production-grade Solana integrations across the entire software stack—bridging traditional enterprise backends with high-throughput Web3 rails. With 5+ years of software engineering experience ranging from high-throughput enterprise systems to leading agile engineering pods, I deliver end-to-end blockchain architectures: from zero-dependency pure-Java wire transaction serialization and institutional compliance engines to responsive Web dApps and Solana Mobile (SMS/MWA) implementations.

I am currently opening a select window for high-performance teams and institutional builders to leverage my integration expertise. If your project demands elite-level execution, you have the opportunity to secure my availability under the following parameters:

• The Blueprint: End-to-End Solana Integration (Enterprise Backend Rails, Web dApps, or Mobile)
• The Role: Senior Solana Integration Engineer / Web3 Solutions Architect / Enterprise Consultant
• Engagement: 3–6 Month Contracts (Sprint, Milestone, or Advisory-based execution)
• Timeline: Available immediately for the right project.
• Synchronization: Full-time Remote with 100% overlap with US Eastern Time (EST) hours.

I do not just write code; I design fail-closed architectures, eliminate external dependency bloat, and accelerate shipping timelines for Agile Web3 teams. Whether you are tokenizing real-world assets (RWAs), building low-latency indexers/adapters, or launching a consumer dApp, let’s talk.

• 1. Enterprise Core & Protocol Integration (Backend First):

  • Low-Level Solana Serialization: Custom zero-dependency pure-Java wire serializer (SolanaTransactionSerializer) supporting compact-u16 varints, canonical 4-category account classification, and legacy wire message generation.
  • Cryptography & RPC: Pure Ed25519 multi-signing (net.i2p.crypto:eddsa), dynamic rent exemption calculation (getMinimumBalanceForRentExemption), confirmed commitment retry engine, and resilient JSON-RPC adapters.
  • Enterprise Architecture: Java 21, Spring Boot 3.5, Hibernate/JPA, PostgreSQL, Docker, fail-closed KYC/AML compliance gatekeepers, and append-only audit trail logging.

• 2. Web3 Frontend & Responsive dApps:

  • Modern standalone frontend architecture with TypeScript / Angular 18+, Tailwind CSS, and RxJS state streams.
  • Browser wallet integrations (@solana/web3.js, Phantom, Solflare), self-custody transaction signing, and dynamic explorer linking.

• 3. Native & Cross-Platform Mobile:

  • Solana Mobile: Solana Mobile Stack (SMS), Mobile Wallet Adapter (MWA) integrations, seed vaults, and native Web3 wallet flows.
  • Mobile Frameworks: Native Android (Kotlin, Java), React Native, memory optimization, low-latency state caching, and responsive UI.

• 4. Agile Engineering Leadership:

  • Certified Professional Scrum Master (PSM I), test-driven development (TDD), CI/CD pipelines, and active sprint management to eliminate technical blockers.

🌉 solana-rwa-enterprise-bridge

Enterprise-grade bridge connecting off-chain Spring Boot infrastructure (KYC/AML compliance gatekeeper, immutable audit trail, PostgreSQL) directly to Solana Devnet RPC. Features a pure-Java binary transaction wire serializer, dynamic rent exemption, and atomic 2-instruction SPL token minting with 107 passing backend tests.

• Zero-Dependency Wire Protocol Engine: Architected and implemented a pure-Java Solana transaction serializer and Ed25519 multi-signer, removing heavy external Web3 SDK bloat for enterprise microservices.
• Fail-Closed Compliance Gatekeeping: Built strict regulatory guardrails that prevent unverified wallets from ever hitting the Solana RPC layer, logging all decisions to an immutable, append-only PostgreSQL audit trail.
• Multi-Surface Execution: Successfully deployed production architectures across Enterprise Java/Spring Boot backends, Angular web dApps, and Solana Mobile Stack native/hybrid applications.

I am available for high-impact consulting contracts (3–6 months) and senior integration roles with teams looking to bridge enterprise infrastructure or ship high-performance Solana applications.
