How We Work

From requirements to production in clear, predictable phases — you see progress every week, not a black box.

06
01

Discovery & Scoping

We define your requirements, map out features, and choose the right tech stack. You'll get a clear project scope, timeline, and cost estimate before any code is written.

02

Architecture & Setup

We design the system architecture, set up the development environment, CI/CD pipeline, and database schema. The technical foundation is built for long-term maintainability.

03

Core Development

We build in weekly sprints with regular demos. You'll see working features each week — not a black box that appears months later. Feedback loops are fast and frequent.

04

Integration & API

We connect your app with third-party services, payment gateways, CRMs, or any external systems. All integrations are tested and documented.

05

Testing & QA

Thorough testing across devices and browsers. We fix bugs, optimize performance, and ensure security before anything goes live. Your product launches solid.

06

Launch & Handover

We deploy to production, set up monitoring, and hand over everything — source code, documentation, and admin access. Then we stay available for 30 days to support you.

Tech Stack

We choose the right tools for each project

Frontend

Next.js / React

Our go-to for web applications. Server-side rendering, static generation, and a rich component ecosystem for fast, SEO-friendly experiences.

React Native

Cross-platform mobile apps sharing code with your React web app. One team, one codebase, native performance on iOS and Android.

Flutter

Google's UI toolkit for pixel-perfect mobile apps. We use Flutter when custom animations and platform-specific polish are priorities.

Backend

Node.js

Fast, event-driven APIs with NestJS or Express. Ideal for real-time features, microservices, and sharing code between frontend and backend.

Python

Our choice for AI/ML pipelines, data processing, and automation. Python's ecosystem makes complex integrations straightforward.

Go

When raw performance is critical. We use Go for high-throughput microservices, real-time systems, and infrastructure tooling.

Database

PostgreSQL

Our default relational database. Advanced query support, JSON capabilities, and proven reliability for mission-critical applications.

MongoDB

Flexible document store for applications with evolving schemas. Ideal for content platforms, catalogs, and rapid prototyping.

Redis

In-memory data store for caching, session management, and real-time leaderboards. Makes your application feel instant.

AI & ML

OpenAI

GPT models for chat interfaces, content generation, and function calling. Integrated across client products for intelligent user experiences.

LangChain

Our orchestration layer for chaining LLM calls, tool use, and retrieval-augmented generation into production-ready AI applications.

pgvector / Vector DB

Powering semantic search, RAG pipelines, and long-term AI memory. We use pgvector, Pinecone, or Qdrant depending on scale.

Infrastructure

AWS

Full-service cloud for enterprise workloads. We leverage Lambda, ECS, S3, and CloudFront for globally distributed, auto-scaling architectures.

Google Cloud

Our pick for AI/ML workloads and data-intensive applications. BigQuery, Vertex AI, and Cloud Run power our smartest solutions.

Vercel & Docker

Vercel for frontend deployments with edge functions. Docker for consistent environments from development to production.

Integrations

Midtrans & Xendit

Indonesian payment gateways for credit cards, bank transfers, e-wallets, and QRIS. We handle the full integration — checkout flow to settlement.

WhatsApp API

Automated messaging, order notifications, customer support bots, and two-way conversations integrated into your application.

Google Workspace

Sheets, Drive, Calendar, and Gmail API integrations to connect your business tools and automate manual processes.

FAQ

Common questions

A focused MVP usually takes 8-12 weeks. Larger platforms with multiple integrations can take 4-6 months. We'll give you an honest estimate after our discovery session — we don't commit to timelines we can't keep.

Yes. We regularly take over or extend existing projects. We'll audit the current state, identify any technical debt, and propose a path forward.

We choose based on your project's needs, not our preferences. Our most common stack is React/Next.js on the frontend, Node.js or Python on the backend, and PostgreSQL for data — but we adapt to what makes sense for your use case.

Yes. We offer monthly support and maintenance packages covering bug fixes, minor feature additions, server monitoring, and security updates. Pricing depends on the scope.

Dedicated project channel on Slack or WhatsApp, weekly status updates, and biweekly demos. You'll always know what's happening.

We follow security best practices including encrypted data at rest and in transit, role-based access control, and regular dependency audits. For healthcare or financial projects, we implement additional compliance measures.
