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.

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

PHPJoomlaMySQL

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.

Jonathan Merlin Greenberg portrait

Background

Jonathan Merlin Greenberg spent years as a lead developer in insurance, music and education technology, managing teams and architecting complex systems that had to handle real-world complexity. Policy management platforms. Student information systems. The kind of software where "mostly working" isn't good enough because people depend on it every day.

That experience built deep technical expertise — but it also revealed how much friction traditional development shops introduce. Endless meetings. Miscommunication between departments. Junior developers who need constant supervision. Project managers managing the managers. The actual building often felt secondary to the coordination.

So he founded Macrolific with a different model in mind: a lean, senior-led operation where the focus stays on building great software, not managing overhead.

Why Boutique

This isn't about being small for the sake of being small. It's about economics and execution.

A traditional agency assigns your project to a mixed team: maybe one senior dev, a couple of junior developers, a designer, a project manager. You're paying for all of them, plus the overhead of coordinating them. Most of that cost isn't going toward building your application. It's going toward managing the process of building your application.

Macrolific works differently. A small, senior team — led by Jonathan and augmented by AI-assisted workflows — builds your project, while the routine work traditional shops throw at junior developers gets automated. The complex parts get experienced attention. No bloated org chart. No telephone game where requirements get distorted passing through five people.

This model changes the economics completely. You get senior-level architecture and decision-making on every aspect of your project, at a cost structure that used to only buy you a mixed team of varying skill levels.

How We Work

We're not interested in churning out WordPress sites or template-based applications. Our background is in custom systems that solve specific problems: business logic that matches your actual operations, integrations that connect your tools, data models that reflect how you really work.

People assume there's a tradeoff between building things right and building them fast. There isn't — not when you know what you're doing. Good architecture actually moves faster because you're not constantly backtracking to fix structural problems. Clean code is easier to modify than messy code. Proper planning prevents the expensive rewrites that bloated teams mistake for "agility."

We build things right the first time, and we build them efficiently.

AI assistance accelerates the straightforward parts — boilerplate code, standard implementations, routine debugging. That frees our senior developers for what actually matters: understanding your business logic, making architectural decisions, solving the problems that don't have template answers.

What This Means For You

When you work with Macrolific, Jonathan leads your project personally. No salesperson who hands you off to a delivery team. No project manager interpreting your requirements. No wondering whether the person making architectural decisions actually understands your business.

You get a team that has built complex systems, that understands both the technical and business sides, and that can have a real conversation about tradeoffs and priorities.

Macrolific works with clients who need custom applications built correctly — whether that's a workflow automation tool, a customer portal, a data management system, or something entirely specific to how your business operates.

If you need a brochure site or something a template can handle, there are cheaper options. If you need actual software engineering — a team that can think through your requirements, architect a real system, and build it properly — then we should talk.
