STUDIO_LIFECYCLE // STAGES 01 → 04

PIPELINE_ACTIVE
  1. 01 COMPILED

    Design & Arch

    Data contracts, API schemas, microservices topologies, and frontend state architectures mapped before code begins.

  2. 02 BUILDING....

    Build & Integrate

    High-concurrency cloud services, native mobile and Android TV clients, and LangGraph-driven AI agent pipelines.

  3. 03 VERIFYING [QA]

    Test & Automate

    Automated Playwright suites, API regression gates, JMeter load runs, and AI prompt/hallucination validation matrices.

  4. 04 SHIPPED // LIVE

WHAT WE BUILD

Full-system software engineering.

Most technology projects stall when backend developers, mobile builders, and QA testers work in disconnected silos. We operate as a single studio covering the entire technical stack.

  • • Resilient Spring Boot & Java microservices
  • • Event-driven messaging with Kafka & SQS
  • • Multi-region PostgreSQL, Redis & MongoDB
MOBILE, TV & FINTECH

Mobile & Big-Screen Apps

Native iOS (SwiftUI) and Android (Kotlin) apps, cross-platform Flutter builds, 10-foot Android TV experiences (ExoPlayer & DRM), and PCI-compliant payment integrations.

  • • Cross-platform Flutter & native Swift / Kotlin
  • • Android TV Leanback, ExoPlayer & D-pad nav
  • • Stripe, Plaid, PayPal & 3D Secure workflows
QA & AUTOMATION

QA & Test Automation

Comprehensive automated regression suites, API stress testing, cross-browser Playwright & Appium runners, and AI evaluation suites to catch regressions before release.

  • • Playwright & Cypress cross-browser suites
  • • Postman/Newman & JMeter API load tests
  • • LLM prompt validation & RAG retrieval gates
PYTHON & AI WORKFLOWS

AI-Powered Applications

FastAPI services, LangGraph multi-agent systems, retrieval-augmented generation (RAG) pipelines, Model Context Protocol (MCP) server development, and full-stack React UIs.

  • • FastAPI, Django & async Celery task queues
  • • LangGraph agentic workflows & vector search
  • • Custom Model Context Protocol (MCP) servers

HOW WE WORK

The in-house studio advantage.

Traditional agencies introduce layers of non-technical management, fragmented subcontracting, and disjointed handoffs. Our studio handles the full lifecycle under one roof.

01

Zero Handoff Friction

Architecture, backend schema, client apps, and QA automation are designed cohesively. We never outsource critical pieces to third-party subcontractors or offshore brokers.

02

Automated QA From Day One

Test automation is written concurrently with feature development. Every pull request runs through automated CI gates, preventing regressions before reaching staging.

03

Direct Engineer Communication

You collaborate directly with the engineers building your software via Slack, Discord, or GitHub. Technical decisions are made with zero intermediate filtering.

04

Turnkey Production Delivery

Every deliverable includes complete CI/CD pipelines, Docker container manifests, automated regression test suites, and monitoring dashboards for seamless ownership.
