I'm Drake Lesher, a software engineer and Computer Science graduate of Wofford College currently building cross-platform security software at Resistine, where I work across Python desktop apps, native iOS (Swift), antivirus integration, VPN systems, and SIEM monitoring. I partner with founders, small teams, and non-technical clients from first sketch all the way through shipping and support.
Security software: endpoint protection, ClamAV, Wazuh SIEM, VPN, encryption
Full-stack web: React, Next.js, FastAPI, TypeScript, Docker, WebSockets
Native mobile: Swift/SwiftUI (iOS)
Data & AI: Monte Carlo simulations, xG models, LLM integrations, NumPy pipelines
Desktop & games: Python (Briefcase), C#/.NET, Godot (GDScript)

Services
What we build.
Six focused practices, all delivered by the same person who wrote the proposal. No handoffs, no hidden subcontractors.
Custom Software Development
Internal tools, automation, backend services, and APIs built to the shape of your business.

Process
How we work.
A simple four-step process designed around giving you confidence and control at every stage.
01
Discover
Scope the real problem, the constraints, and what success looks like. Fixed-fee discovery for new engagements.
02
Design
Technical proposal, architecture sketch, and a clear document outlining scope, timeline, and deliverables.
03
Build
Iterative delivery with working demos — not surprises at the end. You see progress every week.
04
Deliver
Deploy, document, hand off, and offer ongoing support when it makes sense to keep working together.
Selected work
Projects.
A selection of professional, personal, and academic projects across security software, full-stack development, data science, and game design.
Grant Research Automation
