CRMs with AI baked in — lead scoring, call summaries, next-best-action.
AI Workflows
Automate the busywork between your tools with AI-driven pipelines.
RAG Development
Assistants that answer from your own documents and data — accurately.
Chatbots & Agents
Support and sales bots that actually resolve, not deflect.
Products we've shipped
RAG AI Knowledge Base & Document Chatbot
Built an end-to-end Retrieval-Augmented Generation (RAG) system in Python for querying a private document knowledge base. The system ingests structured Markdown documents, splits them into meaningful semantic chunks by heading, paragraph, list, table and code block, and converts each chunk into a 384-dimensional embedding stored in Qdrant with its source file, chunk number and heading path. A user's question is embedded and matched against the closest chunks, which are passed to a local Ollama/Gemma LLM to generate a grounded answer — with source transparency and multi-turn conversation history.
TaskFlow AI
TaskFlow AI combines traditional project management with a conversational AI assistant, real-time voice interaction, and a RAG-powered knowledge base. Users manage projects and tasks through the interface, or simply ask in natural language or by voice — the AI converts requests into real actions through function calling, with confirmation on anything critical and a full activity log. Teams can also upload project documents and ask the AI questions about them, with answers backed by cited sources. Built with React, Node.js, Express, MongoDB and OpenAI GPT-4o.
Industries we serve
Software works best when it fits the way your industry actually operates. Here is where we build most.

Booking, patient portals and assistants that cut front-desk workload.
