An end-to-end platform that automates business processes using custom event-driven workflows, saving teams 20+ hours per week.


Opsidian
Knowledge work gets fragmented when tasks, notes, and events live in separate places with weak relationships.

TrackiFi
Personal finance tools often record transactions without helping users understand the behavior behind their spending.

Booking SaaS
Service businesses lose revenue when scheduling, availability, and client bookings are handled through scattered tools and manual coordination.
Selected work only
Most client systems are internal tools and private dashboards I can't publish. Happy to walk you through them live on a call.

Four steps, no surprises
Every project runs the same way, so you always know what happens next and what you get at the end of it.
Scope call
30 minWe go through the problem, the constraints, and the budget. You leave with a clear view of what is buildable now and what should wait.
Written scope + fixed quote
System design
2–4 daysBefore any code, you get the plan: screens, data model, integrations, and a milestone list. This is where the expensive mistakes get caught.
Architecture doc + milestones
Build
1–3 weeksShipped in tight iterations with a working demo every week. No month-long silences, no surprise scope creep.
Weekly demo you can click
Handover
1–2 daysDeployed, documented, and fully yours. Source access, database guide, and a walkthrough so your team can take it forward without me.
Live system + full ownership
Tell me what you're stuck on.
Get a clear plan, fast execution, and a working outcome without turning the build into months of uncertainty.
