Custom Software Development & Penetration Testing in Birmingham, AL

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 Birmingham remote-first — Macon keeps a one-hour offset to Central Time and full working-day overlap — with travel into Jefferson and Shelby counties for major builds and on-site network work. Birmingham operators in healthcare, finance, and insurance typically need the same things: HIPAA-aware and PCI-aware platforms, ops dashboards that unify legacy systems, and pen test reports that survive a compliance audit.

Birmingham's economy is anchored by regulated industries. UAB and UAB Medicine are the largest employer in Alabama, driving an academic-medical and biotech ecosystem — including the Southern Research and Innovation Depot startup scene — that runs on intake, scheduling, and clinical operations software. The city has a deep financial-services history and remains a regional banking and payments center. Birmingham is also one of the South's notable insurance and employee-benefits hubs, with carriers and benefits administrators that need policy, claims, and broker software. Layer in the engineering base around the US-280 corridor and Hoover, plus the University of Alabama an hour away in Tuscaloosa, and you have a metro whose software needs are dominated by compliance-sensitive verticals.

Most Birmingham shops are either large regional 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 UAB-adjacent health operator needs a HIPAA-aware platform, or when an insurer needs both a custom claims system and a pen test report that maps to their compliance obligations.

Birmingham buyers in regulated industries want senior accountability and a clean audit trail. Our model delivers exactly that: every engagement is scoped, built, and shipped by the founder, on a fixed-scope and fixed-price proposal with a written acceptance milestone — not open-ended time-and-materials billing. Our pen testing is in-house capability, not a subcontracted line item: Active Directory abuse paths, lateral movement, ADCS certificate abuse, Kerberoasting, wireless attacks, and web application exploitation, 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 work from Macon on a one-hour offset to Birmingham's Central Time, which still leaves a full working-day overlap for standups and reviews. Most kickoffs are a video call followed by a single on-site afternoon — typically downtown, in Hoover, or along the US-280 corridor — 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 Birmingham 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 Birmingham engagements close inside 4–6 weeks from kickoff to final report.
