    01 — The Engineer

    The engineer behind the systems.

    I'm a Senior Software Engineer with 3+ years of experience who treats software like a product, not a task list. My recent work at Vusic Technologies and Turtleneck Systems has been deep in the trenches of distributed systems — designing platforms that hold up under 50K+ concurrent users, handle gigabyte-scale encrypted workloads, and stay responsive in milliseconds, not seconds.

    My playground is system design: choosing the right boundaries between services, picking the right consistency model, knowing when to reach for Kafka or RabbitMQ, when Redis is enough, and when the answer is simply a better data structure. I obsess over the tradeoffs most teams skip — and that's usually where the real reliability lives.

    Beyond the code, I lead. I've owned features end-to-end, mentored engineers, translated fuzzy product asks into crisp technical roadmaps, shipped demos and walkthroughs for clients, and operated production systems with real observability. Ownership isn't a buzzword for me — it's the default mode.

    The vision needs an architect.

    02 — The Craft

    What I build for teams that can't afford to break.

    A focused set of services designed for companies serious about scale, reliability, and velocity.

    03 — Selected Work

    Real systems. Real scale. Real impact.

    A handful of projects that show how I think about complex problems.

    01Case study

    Real-Time Auction Platform

    Live bidding for 50K+ concurrent users.

    Problem

    Auctions where every millisecond matters — bids must be globally consistent, fair, and instantly reflected for every viewer.

    Solution

    Event-driven core on Kafka and RabbitMQ with Redis-backed bid state, WebSocket fan-out, and idempotent write paths to guarantee correctness under bursty load.

    Impact

    Supported 50K+ concurrent users while reducing end-to-end latency from 500ms to 120ms.

    File Processing Microservice

    Encrypted streaming for 1GB+ payloads.

    Problem

    Single-shot uploads of large files were failing, blocking memory, and leaking sensitive data on retries.

    Solution

    Chunked, resumable uploads with AES-256 and RSA encryption, BullMQ background jobs, parallel worker processing, RBAC, and signed URL delivery.

    Impact

    Reliable processing of 1GB+ encrypted files with constant memory footprint and secure access controls.

    AI Health Engine

    Voice-first AI for clinical workflows.

    Problem

    Care teams needed instant, contextual answers from health data without typing or navigating dashboards.

    Solution

    RAG pipeline blending LLaMA and OpenAI with Supabase vector search and ElevenLabs voice interaction behind a hardened API.

    Impact

    Reduced query-to-insight time from minutes to seconds with conversational, multi-modal access.
