CreatrHub

Built by Launchwoven

Creator management platform

CreatrHub helps brands find, hire, and manage content creators. Launchwoven handled the project end to end, from the product design to the backend systems behind the platform's day-to-day operations: how jobs move through their workflow, how creator payouts are structured, and how activity is recorded and turned into notifications for users.

Work like this depends on careful data modelling and dependable state handling, because jobs, payments, and notifications all need to stay consistent with one another.

Blissa

Built by Launchwoven

Social and events application

Blissa is a social and events app available on Android, with a categorized social feed, posts, and user accounts. Launchwoven handled the project end to end, from the product design and the Android app itself to the backend infrastructure, system engineering, and core web integrations behind it.

WetroCloud SDK

Built by Launchwoven

AI platform SDK

WetroCloud builds custom AI solutions for businesses, including retrieval-augmented generation (RAG) systems, agents and an AI gateway. Launchwoven designed and built the JavaScript and TypeScript SDK for the WetroCloud API, so developers can work with the platform from their Node.js applications through a typed client instead of raw HTTP calls.

The SDK covers collections and resource ingestion, RAG queries and chat with streaming responses, content categorization, text generation, image-to-text, structured data extraction from websites, markdown conversion and video transcripts. It is published on npm.

Example: querying a collection with the SDK

import Wetrocloud from "wetrocloud-sdk";

const wetrocloud = new Wetrocloud({ apiKey });

await wetrocloud.insertResource({
  collection_id,
  resource: "https://example.com/report",
  type: "web",
});

const answer = await wetrocloud.queryCollection({
  collection_id,
  request_query: "What are the sales trends for Q1?",
});

Independent builds

Systems we have built independently.

Self-initiated projects across backend systems, developer tooling and applied AI, with the source code available to review.

Independent build

ServerDevTools

Open-source developer tool for Node.js

A request inspector for Node.js backends, like browser DevTools for the server. It shows what happened during each request, from the incoming data to database queries, outbound API calls, errors and timings, in one local dashboard.

Technical contributions: In-process middleware that serves its dashboard from the application's own server, OpenTelemetry instrumentation for MongoDB, PostgreSQL, MySQL, Redis and outbound HTTP and fetch calls, request execution trees with timings, SQLite-backed history, default header redaction with optional field encryption, and Express and NestJS integrations.

Content scheduling and admin platform

Social media management platform.

Technical contributions: REST API (Django REST Framework), scheduled and recurring posts with Celery Beat, bulk upload, content moderation workflow, media library, user and activity management, and Swagger API docs.

5G Root-Cause Diagnosis with an Edge-Sized LLM

AI diagnosis system

AI system that reads raw 5G network telemetry and explains in plain language why throughput collapsed.

Technical contributions: LoRA fine-tuning of a 4B-parameter open-source LLM small enough for an edge server, deterministic Python measurement pipeline that turns raw telemetry into plain-language inputs, and evaluation that raised accuracy from ~12% to 99.1% on 863 held-out cases.

Document Assistant (Chat with your PDFs)

AI document assistant

Retrieval-augmented assistant that answers questions from a company's own PDFs.

Technical contributions: Page-aware chunking and vector search, grounded answers with page citations and a sources panel, multi-document upload, streaming responses, support for any OpenAI-compatible model provider, Docker deployment, and an automated test suite with CI.
