Kaica is an engineering studio. Mobile, web, and backend systems for businesses that need more than a template — built lean, with senior hands and modern tooling end to end.
Most of our work is under NDA. Names abstracted, architecture generalized — but everything below is real, in production, and earning its keep.
A two-app ecosystem connecting customers with vetted service professionals. Booking, in-app messaging, escrowed payments, and reputation — designed around regional payment rails and multi-language localization from day one.
A unified API that abstracts regional payment providers behind a single endpoint. Webhook normalization, idempotent retries, reconciliation logging — the unglamorous work that keeps revenue flowing.
A visual dashboard that pulls from carrier APIs to track international freight in real time. Customs milestones, ETA recalculation, status alerts by reference number.
Built for a wholesale manufacturer tired of generic SaaS. Client interactions, order history, payment status, aged receivables — exactly what their team uses every day, and nothing else.
A full-stack appointment platform with timezone-aware calendars, transactional emails, and rescheduling links. The kind of polish that makes customers think they're using a much bigger product.
Most agencies hand you a templated WordPress site. We hand you a fast, custom, maintainable codebase that loads in under a second and ranks because it actually deserves to.
High-converting landing pages and brand sites. Custom design, no template smell. Built for performance — Lighthouse scores you can take to a board meeting.
Storefronts that don't fall over on launch day. Custom checkout flows, inventory sync, regional payment integration. Headless when it makes sense, monolith when it doesn't.
The unglamorous web apps your operations team actually lives in. Role-based access, audit logs, exports, and the kind of UX that makes power users faster, not slower.
Editorial sites, blogs, knowledge bases, and documentation portals. We pair a writer-friendly CMS with a developer-friendly stack so neither side compromises.
Full-stack SaaS products from zero. Authentication, billing, multi-tenancy, real-time updates. The boring foundations done right so your features can be interesting.
Inherited a slow, broken, or abandoned site? We audit, stabilize, and refactor. Sometimes the right move is a careful migration, sometimes a clean rewrite — we'll tell you honestly which one yours needs.
We don't ship sites that need a maintenance contract on day one. Every engagement comes with these as default — not as upsells.
Personal projects, prototypes, and works-in-progress. The systems we don't get to touch in client work — explored on our own time, on our own terms.
A long-running personal experiment in scalable game-server architecture. Player-driven economy, isometric rendering, asynchronous city-building, server-authoritative state.
Stress-tested against synthetic load — a long way from a launched game. Treated as our personal sandbox for distributed-systems problems.
A backend for a hypothetical economy that adjusts commodity prices across virtual cities via supply-and-demand. The hard part isn't the math — it's keeping fifty interconnected markets stable.
A central place to tag and retrieve our own code blocks and AI prompt templates. Built it because we kept losing track of the same useful patterns across repositories.
TradingView indicators and signal scripts. Sold and licensed independently. We treat trading code with the seriousness money deserves — explicit rules, no curve-fitting, full transparency.
Overlays higher-timeframe direction onto lower charts. Filters noise and false breakouts at the source.
Strict crossover signals dispatched to exchanges via webhook. Designed to remove discretion, not replace judgment.
Identifies hidden liquidity zones, alerts on structural breaks, plots optimal R:R entries on re-tests.
Thirty minutes. Free. We figure out together if your problem is something we can solve well — or whether you'd be better served elsewhere. We'll tell you honestly.
Fixed-price scope with milestones and a real timeline. No "we'll figure it out as we go." If the spec changes mid-project, we re-quote — both sides protected.
Weekly demo links. Your code lives in your repository from day one. No black box, no last-minute reveal — you watch it grow.
Documentation. Deployment runbook. A 30-day window for bug fixes after launch. After that — retainer if you want us, freedom if you don't.
The best engagements start with a clear problem and a written brief. Send a few lines about what you're building, your timeline, and any constraints. We reply within two working days — or tell you upfront if we're not the right fit.
