Watch Buldr in action - A unified platform for the next generation of engineers

Project Overview

Buldr is an all-in-one digital platform designed specifically for engineers to learn, build, showcase, monetize, and get hired. It combines social networking, AI-powered assistance, project marketplaces, portfolio generation, and IoT device management into a single, extensible ecosystem.

At its core, Buldr treats engineering as a form of artβ€”enabling engineers to present their creations with the same visibility and value that designers enjoy on platforms like Dribbble or Sketchfab.

Core Modules

Account Management

Manage user identity, profiles, project previews, and generated portfolio sharing.

BuldrAI Chatbot

Domain-specific AI assistance trained on engineering curricula with source-cited responses.

Project Creation

Structured creation with AI-assisted text, image generation, and code blocks.

Social Module

Foster community engagement, share projects, and discover inspiration.

Marketplace

Buy and sell engineering projects with seller-side management tools.

Generated Portfolios

Automatically create professional portfolios from user profiles and projects.

IoT Device Management

Control real-world hardware like data collection bots, drones, and RFID systems.

Problem Statement

Fragmented Platforms

No dedicated platform for engineers to showcase projects in a structured manner.

Lack of Domain AI

Existing LLMs lack specific engineering training and curricula context.

Hiring Disconnect

Difficult for companies to directly discover and hire technical talent based on project work.

The Solution

Buldr addresses these gaps by providing a unified engineering-focused platform with domain-trained LLM assistants, project-centric social features, automatically generated portfolios, and pluggable IoT device management modules.
