Custom Software Development & Penetration Testing in Orlando, FL

QUANT LAB USA pairs custom software engineering with hands-on penetration testing rooted in the MITRE ATT&CK framework. We are a Macon, Georgia firm serving Orlando remote-first across the same Eastern Time zone, with travel into Orange, Seminole, and Osceola counties for major builds and on-site network work. Orlando operators typically need the same things: high-volume booking and billing that does not buckle on a peak weekend, ops dashboards that unify legacy systems, and security reports that survive a PCI or vendor review.

Orlando's software demand is unusually diverse for a metro its size. The tourism corridor along International Drive and the attractions belt — Walt Disney World, Universal Orlando, SeaWorld, and the resort and convention economy feeding the Orange County Convention Center — runs on reservations, ticketing, capacity management, and guest-experience tooling at enormous transaction volume. Lake Nona's Medical City pulled the University of Central Florida College of Medicine, Nemours Children's, the VA Medical Center, and a deep life-sciences tenant base into one district, all of which need HIPAA-aware platforms. The Central Florida Research Park beside UCF is the densest modeling, simulation, and training cluster in the nation, anchored by the military's simulation commands and a long bench of defense contractors. Add a fast-growing fintech and SaaS scene around Lake Mary and downtown, and you have a city that is hungry for serious custom software.

Most Orlando shops are either large tourism-IT integrators or solo freelancers. We sit in the middle: founder-led delivery with enterprise-grade engineering practices and in-house offensive security. No offshore handoff and no junior outsourcing — William Beltz scopes, builds, and ships. That matters when a peak-season booking flow has to stay up under load, or when a Lake Nona health operator needs both a custom platform and a pen test report that maps to their compliance obligations.

Orlando buyers have been burned by agencies that win the pitch with a senior team and deliver with offshore juniors. Our model removes that risk. Every engagement is scoped, built, and shipped by the founder, on a fixed-scope and fixed-price proposal with a written acceptance milestone — no open-ended time-and-materials billing. Our pen testing is in-house capability, not a subcontracted line item: Active Directory abuse paths, lateral movement, web application exploitation, and wireless attacks, with every finding mapped to a MITRE ATT&CK technique ID. And every line of software we ship is reviewed against the same threat models we use on offensive engagements.

We run full Eastern Time overlap from Macon, which keeps standups and reviews on Orlando's clock. Most kickoffs are a video call followed by a single on-site afternoon — typically downtown, in Lake Mary, or near Lake Nona — to walk the workflow we are replacing. From there, build cycles run weekly: every Friday you get a deployed staging URL, written notes on what changed, and the next-week plan. Pen testing engagements run from secure remote infrastructure with strict source-IP allowlisting and authenticated VPN tunnels for internal scope, and we travel to Orlando for sensitive scoping and for internal tests requiring on-site network access. Reports ship in two formats: a technical deliverable with reproduction steps for the security team, and a board-readable executive summary with a prioritized remediation roadmap. Most Orlando engagements close inside 4–6 weeks from kickoff to final report.
