I am a Senior Systems & Polymath Software Engineer with a multidisciplinary engineering foundation spanning computational mathematics, low-latency systems programming, real-time AI & voice agents, cross-platform applications, and decentralized Web3 protocols.

My core differentiator is ultra-high learning velocity and first-principles reasoning: Whether descending into low-level memory management in Rust/C++, designing numerical algorithms for structural mechanics simulation, building streaming full-duplex telephony AI pipelines, or auditing Soroban smart contracts, I assimilate unfamiliar codebases and complex problem domains in days—delivering deterministic, zero-defect production code with automated test coverage from day one.

💼 I am actively open to compelling engineering challenges: Senior Full-Stack, Systems Engineer, AI / Audio Infrastructure, or Tech Lead roles (Full-Time, Contract, or Architectural Advisory).

• Numerical Engines: Built mathematical computation suites for structural mechanics, finite-element calculations, matrix operations, and symbolic solvers.
• Precision & Performance: Designed memory-efficient algorithms for handling large sparse matrices with strict floating-point error bounds and real-time visualization.
• Cross-Platform Deployment: Authored unified algorithmic cores shared across desktop and mobile execution targets.

• Full-Duplex Audio Pipelines: Engineered low-latency voice agent backplanes integrating real-time microphone stream ingestion, neural TTS, streaming STT, and LLM tool execution.
• Resilient State Recovery: Handled packet jitter, socket drops, and mid-stream interruption protocols for production telephony use cases.
• Model Agnostic Orchestration: Designed pluggable interfaces for multi-model fallback, function calling, and structured semantic memory.

• Audio Playback Engine: Implemented background playback services, media session routing, hardware audio focus handling, and seamless stream caching.
• App Optimization: Decompiled, profiled, and refactored media applications for lower CPU usage, minimal memory footprint, and zero battery drain.

• Smart Contract Security Audits: Formalized contract invariants, resolved STORAGE-02 and STATE-10 vulnerabilities, and implemented rolling TTL lifetime management.
• Gas & Footprint Benchmarking: Created empirical benchmark suites measuring instruction count and ledger footprint costs (BENCHMARKS-SOROBAN.md).
• High-Throughput Oracles: Paged Horizon keeper queries in bounded chunks of 50 to eliminate read limits, and fixed compiler hygiene across Rust crates (clippy -D warnings).
• Open Source Leadership: Delivered 50+ vetted, production-grade pull requests with 100% CI pass rates across leading ecosystem repositories.

• 🏛️ B.S. in Computer Science & Applied Mathematics
  • Deep academic foundation in core computer science theory: algorithm design & computational complexity (Big-O asymptotic analysis), abstract algebra, numerical linear algebra, operating systems internals, and distributed networks.
• 📜 Universal Problem Solver & High Learning Velocity:
  • Zero-Ramp-Up Overhead: Demonstrates exceptional ability to enter completely new technological stacks, languages, or domain-specific architectures and produce senior-quality code within hours.
  • First-Principles Thinking: Solves problems by understanding hardware, memory boundaries, and mathematical constraints rather than relying on surface-level abstractions.
• 🛡️ Senior Autonomous Ownership (Zero-Handholding):
  • Proven capability to take ambiguous architectural requirements and execute full lifecycle delivery: from threat modeling and database schema design to automated test suites (vitest, cargo test) and production deployment.

I am always interested in discussing technical challenges, open-source collaborations, and exciting career opportunities.
