The studio
Digital products, built for real work.
We design and build websites, software, and AI systems around the way your business works.

Our approach
Good software starts with a clear purpose.
We make the important decisions early: what to build, who it serves, and how it should work.
We turn complex business needs into digital products people can use with confidence.
From the first product decision to the final release, our strategists, designers, and engineers work as one team. The result is software shaped around real needs—not a template or a handoff chain.
Our capabilities
From an early idea to a product in use.
Strategy, design, and engineering work together from the start, keeping product decisions grounded in user and business needs.
Web Experiences
Design and build fast, accessible websites that make complex services easier to understand.
Custom Software
Replace manual processes and disconnected tools with software built around your team’s workflows.
Mobile Applications
Build iOS and Android apps for services that need a useful, dependable mobile experience.
Our methodology
A disciplined path from concept to market authority.
Our process eliminates guesswork. We run structured, high-velocity phases where strategic design and systems engineering evolve concurrently.
PHASE [01]STEP 1 / 6
Discover
// Strategic Alignment & Architecture Audit
We dissect your existing software topology, commercial drivers, operational bottlenecks, and user heuristics. Before proposing code or layouts, we establish concrete success benchmarks and defensible roadmaps.
KEY ARTIFACT:Technical Blueprint & Architecture Audit
PHASE [02]STEP 2 / 6
Define
// Product Scope & Core System Schemas
We translate high-level business goals into concrete technical specifications: relational data models, API contracts, entity schemas, and user journeys stripped of non-essential bloat.
KEY ARTIFACT:Schema Contracts & Scope Matrix
PHASE [03]STEP 3 / 6
Design
// Editorial UI & Tactile Micro-Interactions
We forge an unmistakable visual identity: bespoke typography, tokenized color palettes, and motion choreographies tested on actual screens rather than theoretical Figma canvases.
KEY ARTIFACT:Figma Tokens, Design System & Interactive Prototypes
PHASE [04]STEP 4 / 6
Build
// Next.js App Router & Type-Safe Engineering
We write clean, modular, production-hardened TypeScript code. Every component is optimized for sub-second server rendering, zero Cumulative Layout Shift, and full keyboard accessibility.
KEY ARTIFACT:Clean Git Repository & Staging Deployments
PHASE [05]STEP 5 / 6
Launch
// Performance Hardening & Zero-Downtime Deployment
We execute thorough production validation: Core Web Vitals audits, edge CDN caching strategies, automated SEO indexing, and end-to-end security penetration checks.
KEY ARTIFACT:Vercel / AWS Production Deployment & Live Telemetry
PHASE [06]STEP 6 / 6
Evolve
// Telemetry Analysis & Continuous Iteration
Digital products are living systems. Post-launch, we monitor user interaction funnels, conversion rates, and server response times to continually sharpen the competitive advantage.
KEY ARTIFACT:Quarterly Velocity Sprints & Optimization Reports
Selected work
Selected work
A selection of products and platforms we designed and built with client teams.
RekaWallet is a personal finance app that shows your net worth, income, expenses, and savings rate at a glance. Manage all your accounts and savings goals, set category budgets with automatic alerts, and log transactions by scanning receipts or QRIS. Invite members, split bills, and set up recurring payments in one workspace.
Cabinet is a personal library for everything you want to keep: links, notes, drawings, videos, and PDFs. Add anything from one menu, mark favorites, group items into folders, and find them again with search. Write notes with slash commands and sketch ideas on a canvas without leaving the app.
fWallet is a personal finance tracker that shows your net worth, income, expenses, and savings rate on one dashboard. Scan receipts and QRIS screenshots to fill in transactions automatically, set budgets by category, and track your accounts and savings goals.
