I'm Keith Manilla— a software engineer and UX designer. For 17 years I've built web, mobile, desktop, cloud and embedded systems for startups and organizations: secured messaging, VOIP, streaming, agentic AI, mapping and realtime 3D.
From a single-page web app to firmware on constrained hardware — I design and build across the entire stack, with web and mobile as my deepest specialties.
Air-gapped, on-premise systems that fuse siloed data into a single operational picture — entity and link analysis, geospatial and temporal intelligence, and decision support for defense, government and critical infrastructure.
Agentic workflows that replace manual process — autonomous agents that plan, call tools, and act across your systems and APIs end to end.
Production web apps and platforms — from marketing sites to complex, data-dense dashboards and realtime control surfaces.
Cross-platform iOS and Android apps with native-grade performance, offline support and polished interaction design.
Fast, native-feeling desktop software for Windows, macOS and Linux — built on a shared web/Rust core.
Distributed backends and APIs engineered for scale, concurrency and uptime — designed to grow with your traffic.
Software for edge devices and constrained hardware where every byte and millisecond counts.
Training custom models from scratch — vision, time-series, tabular — and fine-tuning open-source LLMs on your own data and domain.
End-to-end product design — UX research, usability testing, UX writing and design systems that ship.
Seventeen years gravitate toward the hard problems — systems that have to be fast, synchronized, intelligent and secure.
Secured messaging, VOIP, live streaming and presence — low-latency systems where state stays in sync across thousands of clients.
AI-powered analytics, autonomous agents and intelligent automation that turn raw data and workflows into leverage.
Interactive maps and location intelligence — routing, geofencing and spatial data rendered at speed.
Augmented reality and realtime 3D experiences on the web and on-device, powered by WebGL and three.js.
Enterprise database applications on SQL Server, PostgreSQL and MongoDB — modelled, indexed and tuned for the long haul.
Specialized applications for government, defense and enterprise — engineered to demanding security and reliability standards.
A focused toolkit chosen for performance and reliability — TypeScript and Elixir for realtime and product velocity, Rust for systems and edge, Python for AI and data.

A cross-section of the kind of work I do — realtime, AI, mapping and enterprise systems across web, mobile, desktop and embedded.
No black boxes. You always know where the project stands, what's next, and why each decision was made.
I start with your users and your goals — research, flows and a clear product spec before a line of code is written.
Systems design, data modelling and interface design that hold up as the product and the team grow.
Tight, transparent iterations with working software in your hands early and often — no black boxes.
Production hardening, observability and a path to scale — plus a partner who sticks around after launch.
Have a product to ship, a system to modernize, or an idea that needs a technical partner? Tell me what you're building — I'll tell you how I'd build it.
