How Festi Dev Assistant Speeds Up AI Code Automation

To support faster, more consistent engineering across Festi Framework, we built the Festi Dev Assistant, an AI-powered development tool that automates documentation, test generation, and plugin creation. Festi Dev Assistant is a domain-aware AI tool for software teams.

Can You Relate?

Your team is growing. Your framework is evolving. But documentation, testing, and boilerplate code don’t keep up.

Does this sound familiar?

“Senior devs are wasting time writing repetitive code.”
“We onboard engineers by sending them old Slack threads.”
“No one wants to write docs – and it shows.”
“Tests get skipped to save time, and bugs pile up.”

That’s where we were – until we built the Festi Dev Assistant.

What We Built

An AI-powered internal tool to speed up plugin development, test coverage, and code documentation.

Key Capabilities

Writes unit tests based on method logic and structure
Scaffolds plugins using internal templates and naming conventions
Rewrites docstrings into clear, consistent formats
Retrieves relevant examples from our own codebase via vector search

Built With

LLM stack: ChatGPT, Llama 3.3, Qwen, DeepSeek R1, Llama-Code
Orchestration via Semantic Kernel
Context retrieval via RAG + Qdrant vector DB
Fine-tuning: LoRA, VeRA, Delta-LoRA
GitLab Review integration for RL-based improvement

These components are stitched together to provide fast, reliable suggestions tailored to our internal tools and framework logic.

Before & After Snapshot

Metric	Before Assistant	After Assistant
Unit test time/module	4 – 6 hours	1.5 – 2 hours
Plugin scaffolding	2 – 3 days	< 1 day
Documentation consistency	~60%	95%+
Dev onboarding time	~3 weeks	1.5 weeks

Why Not Other Tool?

Copilot autocompletes code. Festi Dev Assistant understands your codebase.

Works with your internal framework
Leverages your own plugins and naming conventions
Uses GitLab feedback to learn

It’s not a guesser. It’s a builder – made for your team.

Results

40–60% time saved on boilerplate
Better documentation, everywhere
Faster plugin development with fewer bugs
Accelerated onboarding for new hires
