Services

A few areas of expertise

SaaS Platform Development

We architect and build multi-tenant SaaS platforms designed for scale and operational efficiency. From user authentication and subscription billing to admin dashboards and API infrastructure, we handle the complex foundation work that turns your software idea into a revenue-generating service. Our platforms are built to onboard customers, not just users.

Insurance & Education Technology

We have deep domain expertise in enrollment systems, compliance workflows, and administrative platforms for insurance and education sectors. This isn't generic software development — we understand carrier integrations, benefits administration, student information systems, and the regulatory complexity that comes with both industries. We speak your language and know your constraints.

Music Technology

We build tools for composers, producers, and music professionals — from catalog management and audio metadata systems to licensing workflows and creative production platforms. We understand the intersection of music and technology because we live in both worlds.

Full-Stack Web Development

We build production-grade web applications using Next.js, React, Node.js, PHP, and PostgreSQL. Our full-stack capability means faster delivery, tighter integration, and fewer handoff problems between frontend and backend work. You get a complete application, not disconnected pieces that need stitching together.

AI-Accelerated Development

We use AI tooling to compress development timelines and increase code quality — not as marketing theater, but as infrastructure built into how we work at every level. Most firms treat AI as a buzzword. We treat it as an operational advantage, architecting our workflows around AI-assisted development from first line of code to final delivery. The result is better software, delivered faster, at a cost that reflects how we actually build.

AI Deployment Practice

We deploy AI tooling inside small teams and make it stick — workflow discovery before anything gets built, custom connectors for the systems nobody else supports, written data rules, hands-on training, and a skills library your team owns and can maintain after we leave. Fixed scope, fixed fee. Most AI rollouts fail at adoption, not installation, and that is the part we're actually selling.

Legacy System Modernization

We migrate legacy PHP and Joomla systems to modern stacks without losing data or business continuity. Our approach prioritizes incremental transformation over risky big-bang rewrites, allowing your team to maintain operations while we rebuild the foundation. You get rid of technical debt while keeping what already works.

Composer Catalog: Purpose-Built SaaS for Music Rights Management

Next.js 16PostgreSQLPrismaClerkRender

Music composers face a persistent operational challenge: managing extensive catalogs across multiple projects, clients, and distribution channels. Our client needed a specialized platform that could handle the unique workflows of professional composers — from tracking individual compositions and their various recordings to managing rights information and distributing files with proper metadata embedded.

We architected Composer Catalog as a modern SaaS application using Next.js 16, leveraging its App Router for optimized data fetching and server components where appropriate. This choice provided the performance characteristics needed for handling large file lists while maintaining a responsive interface for catalog browsing.

The platform now manages over 15,000 compositions across its user base, processing hundreds of file downloads daily with metadata perfectly intact. The CSV import system has processed legacy catalogs spanning decades, with the duplicate detection reducing manual cleanup work by an estimated 80%. Composers report that the specialized workflow matches their actual business processes in ways general-purpose tools never could.

Student health insurance enrollment platform interface

Comprehensive Student Health Insurance Platform: Eight Years of Enrollment Excellence

PHPJoomlaMySQLjQueryBootstrap

University health centers face a unique challenge in administering student health insurance programs. These systems must navigate complex insurance regulations, coordinate with carriers, process thousands of time-sensitive enrollments during narrow windows, and provide administrative oversight across multiple institutional stakeholders. The client required a comprehensive platform capable of managing the entire enrollment lifecycle while maintaining strict compliance with insurance industry requirements.

The platform integrated multiple subsystems into a cohesive administrative environment used by university health centers to manage annual enrollment cycles processing thousands of students.

Serving as lead developer across eight years of active deployment, Macrolific provided continuous maintenance, incremental enhancements, and regulatory updates as insurance requirements evolved. This extended stewardship developed deep institutional knowledge of the system's architecture and the domain it served.

Approach

A lean, senior-led studio

Domain expertise

Deep experience in insurance and education technology, with systems built for compliance and scale.

AI-accelerated workflow

Faster delivery without sacrificing review, testing, or architectural rigor.

Senior-level judgment

Every decision is made by a senior engineer, not delegated across layers.

Macrolific is a small development studio. A traditional agency puts your project in front of a mixed team and bills you for the overhead of coordinating them. We architect and build with senior engineers, and let AI-assisted workflows absorb the routine work that other shops hand to junior developers.

You get senior-level judgment on every decision, at a lower cost than a conventional agency.
