Building scalable SaaS products,
AI-powered applications,
and modern web experiences.

About
Not just writing code - building things that hold up.
A short version of how I think about the work, told the way I'd tell it over coffee, not the way it reads on a résumé.
A PC arrived home in 2004 and I've barely looked away since. Not for the games — though Counter-Strike stuck around — but for the realization that typed instructions make a machine do exactly what you ask. I taught myself to code through a mechanical engineering degree, and that original feeling of giving a system precise commands and watching it respond is still what gets me into the chair every morning.
Real-time systems, complex infrastructure, anything where state has to stay correct under concurrent load — that's where my attention naturally goes. Not because it looks impressive, but because the problems are genuinely hard and the margins for error are real. I like building things with operational weight: systems that have to keep working even when conditions get messy.
Most bugs I've traced in production turned out to be architecture decisions wearing the disguise of a code problem. Good structure gives a project the ability to scale, to be read by someone who wasn't there on day one, and to survive changes in requirements without collapsing. I treat architecture as the part of the work that outlasts any individual feature.
Technically correct software that nobody needed is still a failure. I want to understand the problem well enough to push back — to know when a simpler solution fits better, or when the real issue sits upstream of anything code can touch. That clarity is what makes the engineering decisions actually matter, and it's the part of the work I find most interesting.

Featured Work
Products built to hold up in production.
A selection of SaaS platforms and business applications - each solving a specific operational problem, not just a demo.

Sessionora
Multi-tenant booking platform for coaches and service businesses
A booking and client-management platform built for coaches, consultants, and service businesses — handling scheduling, payments, automated reminders, and client history in one workspace.
Problem
Coaches and consultants were stitching together calendar links, payment processors, and spreadsheets to run their practice, losing bookings to double-booked slots and failing to follow up on no-shows consistently.
- Multi-tenant architecture with isolated data boundaries per organization on a shared Postgres cluster
- Real-time availability engine with timezone-aware slot locking to prevent double bookings under concurrent writes
- WebSocket-driven live notifications for bookings, cancellations, and reschedules pushed to the practitioner dashboard
- Stripe-backed billing with usage-based plan tiers and automated invoicing


Engineering Case Studies
How the hard problems actually got solved.
Deeper write-ups on architecture, database design, and the trade-offs behind a few of the harder engineering problems I've shipped.
Experience
Where the work happened.
From first production bug to building my own product - a straight line of learning to ship things that matter.
