SHIP4U — DEVELOPMENT STUDIO — INDIA

FROM IDEATO SHIPPEDPRODUCT.

We design, build and deploy production-grade web, mobile and AI products. Two engineers, the full lifecycle, no handoffs between agencies.

SCROLL TO BUILD

01CAPABILITIES

READY

01 / 04

WEBSITES / LANDING PAGES

Fast, indexable marketing sites built to convert. Under two seconds to first paint on a mid-range Android phone, because that is what most of your traffic is using.

HTML · SSR · ANALYTICS · CMS · SEO

02 / 04

WEB APPLICATIONS

Full-stack products with real authentication, real data and real integrations. Frontend, backend, database, APIs. Built to survive actual users rather than a demo.

AUTH · DATABASE · API · PAYMENTS · ADMIN

03 / 04

MOBILE APPLICATIONS

Cross-platform apps with the backend that makes them work. Built, signed, submitted, and shipped to both stores.

IOS · ANDROID · PUSH · OFFLINE · STORE RELEASE

04 / 04

AI APPLICATIONS

Agents, RAG pipelines and LLM features that do something specific and useful. Evaluated against a test set, not judged by how the demo felt.

AGENTS · RAG · EVALS · TOOL USE · INTEGRATIONS

  • DEPLOYMENT & CLOUD

    CI/CD, infrastructure, domains, SSL, monitoring. Set up once, correctly, so it stops being your problem.

  • MAINTENANCE & SUPPORT

    Ongoing development, fixes and new features. We stay on after launch.

02SELECTED WORK

READY

HearU

W-012025

An AI mental-wellness journal with a voice assistant, shipped on Kubernetes.

OPEN
HearU — AI mental-wellness journal, registration frame.

THE PROBLEM

  • Most wellness apps treat the journal as a text box and the model as a demo.
  • There was no confidential write-and-speak loop that could actually ship on a cluster.

WHAT WE BUILT

  • A FastAPI backend and React journal, with a Gemini voice assistant for people who would rather talk than type.
  • CI on GitHub Actions and a Kubernetes deploy on GCP, so the thing you open is the thing that runs.

04PROCESS

READY
  1. 01

    DISCOVER

    We work out what you are actually building and what it has to do on day one.

  2. 02

    ARCHITECT

    Data model, services, integrations, hosting. Decided before a line is written.

  3. 03

    DESIGN

    Interface and flows, designed against the real data, not against a mood board.

  4. 04

    BUILD

    Weekly deployed builds you can open. No three-week silences.

  5. 05

    TEST

    Real devices, real edge cases, real load. Fixes before launch, not after.

  6. 06

    DEPLOY

    Infrastructure, CI/CD, domains, SSL, monitoring. Handed over documented.

  7. 07

    SCALE

    Ongoing development as the product and the traffic grow.

05STACK

READY

Chosen for the products we build, not for the logos. Tap a technology to see why it is there.

CLIENT

  • Next.js

    Next.js — report jobs queue from Next.js APIs, admin dashboards fetch live data, and the Eidos UI ships on it.

  • React

    React — product surfaces and internal dashboards. The same components talk to FastAPI and to Next.

  • TypeScript

    TypeScript — every line we ship is typed. Catches the bugs that would otherwise hit a client's phone.

  • Python

    Python — FastAPI, LangGraph, workers, and the Astro Engine. The language the AI libraries actually live in.

SERVER

  • Node.js

    Node.js — Next.js API routes and Express services. One language with the client, so two people can own the request path.

  • Golang

    Golang — services that have to stay small and concurrent. Chi when the API is Go; Python stays where the AI libraries are.

  • GraphQL

    GraphQL — the in-house Astro Engine over FastAPI. Typed queries, no paid astrology provider in the loop.

  • FastAPI

    FastAPI — Astro Engine, RAG backends, Eidos. We moved Flask here for async throughput and kept it.

DATA

  • PostgreSQL

    PostgreSQL — relational because Eidos and most products have relationships. We will regret JSON columns in month four.

  • Redis

    Redis — time-decayed affinity, short-term agent memory, job locks around the edges. Used for what it is good at.

  • MongoDB

    MongoDB — report-job locking, structured user memory, CRM lead stores. Documents when the shape actually is a document.

AI

  • Gemini

    Gemini — chat intent and the Eidos critic loop. Default when we need a fast, cheap generation pass.

  • OpenAI

    OpenAI — ranking and chat intent alongside Gemini. Used where the evals say it wins, not by habit.

  • pgvector

    pgvector — embeddings in the same database as the rows they describe. One backup, one query, no sync job.

  • LangGraph

    LangGraph — orchestrator, workers, judge, retries. The TrustAstrology agents and the Eidos critic are graphs, not prompts.

INFRA

  • GCP

    GCP — Pub/Sub into BigQuery, Cloud Run, GCE workers, GCS for 35+ report PDFs. Where the heavy async work runs.

  • AWS

    AWS — VPC, ALB, ECS Fargate, EventBridge, Lambda, S3. Chosen when the job needs a box, a queue, or a cron.

  • Docker

    Docker — the same container on a laptop, on ECS, and on the Eidos box behind Nginx. It ends 'works on my machine'.

  • Azure

    Azure — when the client's estate is already there. Same boxes, queues and crons as AWS, different console.

  • Jenkins

    Jenkins — Eidos deploys to a raw AWS host, Elastic IP, Nginx. GitHub Actions for the repos that do not need a box.

At Ship4u, you work directly with seasoned engineers who design and ship your product end-to-end. You get clear communication, decisions in hours instead of weeks, and nothing is handed off without your knowledge. We take on a limited number of projects to ensure focus, and if a project is not the right fit, we will tell you honestly.
