Services
Choose an area, then open any card to see exactly what you receive.
Software and product engineering
Custom web applications and sites, built to your specification and handed over with the source code and documentation.
Native and cross-platform mobile apps for iOS and Android, from first prototype through to store release.
Manual and automated testing that finds defects before your users do, with clear reports your developers can act on.
Storage and processing systems for data volumes too large for an ordinary database or a spreadsheet to handle.
Scheduled collection of structured data from public websites, delivered clean and ready for your own systems.
Ongoing support and maintenance for your software, with agreed response times and a clear record of the work done.
User research, wireframes and tested interface designs, handed to developers as a complete, usable design system.
Design, build, deployment and maintenance of custom software that fits your processes rather than the other way round.
Internal business systems with the access controls, audit trails and integrations that larger organisations require.
Product scoping, prototyping and delivery for founders and teams turning an idea into something customers can use.

AI and data
A model trained on your own data for your own task, delivered with weights, evaluation results and a retraining plan.
An existing open model adapted to your domain using supervised fine-tuning, LoRA, QLoRA or other PEFT methods.
Human preference data and training loops that improve how a model responds, measured against a held-out evaluation set.
Model training guided by AI-generated feedback against written principles, reducing the volume of human labelling needed.
Reward models that score outputs the way your reviewers would, for use in reinforcement learning and quality checks.
Simulated environments and task suites where agents can be trained and graded automatically, safely and repeatably.
Side-by-side comparisons of model outputs, ranked by trained reviewers and delivered as a clean, documented dataset.
Artificial training data that fills gaps in your real data, checked for quality and for leakage of private records.
Text, image, video, audio and multimodal data labelled to your guidelines, with quality measured at every stage.
Messy data turned into a usable training set, with duplicates, errors and gaps found, fixed and documented.
Clear labelling rubrics and review processes so that different annotators reach the same answer on the same data.
Independent testing of models against your real tasks, with a written comparison of accuracy, cost and speed.
Graded evaluation sets written for your domain, so that model quality can be measured the same way every time.
Structured attempts to make your AI system misbehave, with each failure documented and a fix recommended.
Testing for harmful, biased or off-policy behaviour, measured against the standards your organisation has to meet.
AI and data
AI systems designed around a specific business problem, then built, tested and deployed into your existing operations.
Production applications built on large language models, including the evaluation and cost controls they need to run.
AI that answers from your own documents with citations, tested for accuracy against questions your team really asks.
Search that finds results by meaning rather than exact words, built on a vector database sized for your data.
Keyword and semantic search combined with a reranking stage, so that the best result appears near the top.
Tested, versioned prompts with automated evaluation, so that changes can be released without breaking what already works.
Language models adapted to your field and run in your own environment, so that your data stays under your control.
Systems that work across images, speech and documents together, built for tasks that text alone cannot handle.
Transcription and voice output tuned to your vocabulary and accents, measured on recordings from your own use case.
Agents that hold spoken conversations by phone or in an app, and hand over to a person when they should.
Image and video models for detection, classification and inspection, trained and tested on your own footage or photos.
Scanned and digital documents turned into structured data, with low-confidence results routed to a person for review.
Classification, extraction and summarisation of text, using the simplest method that reaches the accuracy you require.
Recommendations for products, content or actions based on behaviour, with results measured through controlled experiments.
Forecasts of demand, revenue or risk built from your historical data, with their uncertainty stated plainly.
AI and data
Agents that carry out multi-step tasks in your own systems, with defined limits and a full record of their actions.
Several specialised agents coordinated on one task, with clear handovers and shared state that can be inspected.
Secure connections between AI models and your systems, using function calling and Model Context Protocol servers.

AI and data
An engineer embedded with your team to find, build and ship AI work inside your own systems and processes.
A ranked list of where AI would help your business, with estimated costs, risks and a recommended first project.
An honest review of whether your data and systems can support AI, along with what to fix first if they cannot.
A working prototype that proves the idea, then the engineering needed to run it reliably for real users.
AI features added to the product you already have, fitted to its architecture and released behind controlled rollouts.
AI capability added around older systems, with AI-assisted migration where replacing them outright is too risky.
Practical training for your teams using their own work, with guidance on introducing AI tools across the organisation.
Written policies, risk registers and model documentation, so that your use of AI can be explained and reviewed.

About
BUGDEV Ltd is a UK limited company in Cheltenham, registered at Companies House under number 16370794. We are VAT registered, so you can contract with us as you would any UK supplier.
We deliver work in three ways: we add engineers to your team, we build a product for you, or we run a dedicated team on your project. On a dedicated team, we allocate a project manager and you speak directly to the developers.
We also build and operate our own product, TeamTrackin. That means we deal with the same releases, support requests and running costs as the clients we work for.
