Projects
Vellic
Real-time voice conversion hardware for character performers. A standalone wearable that transforms the wearer's voice with sub-second latency. No PC, no phone, no internet: on-device inference on NVIDIA embedded hardware with all-day battery. I rewrote the RVC inference path in Rust, cut end-to-end latency by 60%, and I'm now designing my own architecture. The footage here is raw and unscripted: this is what the prototype sounds like today.
In-home technology support for Dade City, Zephyrhills, and greater Pasco County. A real business I founded and operate under JGlacier LLC. Flat-rate visits, a "solved, or it's free" guarantee, fully insured. I do all of it: the house calls, the bookkeeping, the marketing, and I designed and built the website.
AP4 Sales Forecasting
Led a team of 7 seniors to replace manual Excel forecasting for a real parts distributor. AR, SARIMA, VAR, and Temporal Fusion Transformer models with per-SKU selection, full AWS infrastructure, and a Vue.js app with confidence intervals, delivered into the client's own AWS environment with Excel export for seamless adoption.
OpenMic.site
Real-time queue management for open mic nights and live events. WebSocket-powered live updates, mobile performer signup, full-screen venue displays, and a staff admin dashboard. Fully serverless at ~$0.50/month, and the Music Association at Florida Poly still uses it.
About Me
I'm Jacob Diaz-Iglesias, a software engineer and founder. I spent three consecutive summers at Amazon building high-throughput distributed systems, invited back each year, and earned my B.S. in Computer Science from Florida Polytechnic in June 2026. I run JGlacier LLC, home to Porchlight Tech and Vellic, and I like building practical, well-considered systems and understanding how software connects to the hardware and people who use it.
Outside of work, I'm a car enthusiast 🏎️ and motorcycle rider 🏍️, a tenor saxophonist 🎷, and an Eagle Scout ⚜️. I value integrity, determination, and above all positive intent, and I try to carry those principles into my work and life as a lifelong learner.
I'm currently open to full-time software engineering roles, and to contract work through JGlacier LLC. I work primarily in Python, TypeScript, and Java, and the problems that excite me most are real-time audio, ML systems, and health tech.
