Citrusbug delivers machine learning as separate workstreams or one lifecycle, from data pipelines to model monitoring, alongside wider artificial intelligence services such as generative AI and agents.
Classification, regression, and ranking models built with scikit-learn, XGBoost, or PyTorch on your own records, with precision and recall targets tied to what a false positive costs your business, agreed before any training run starts.

Time series models built with Prophet, LSTM, or gradient boosting to forecast demand, churn, and credit exposure, validated on held-out periods so accuracy figures reflect months the model has never seen.
Spark and Airflow pipelines that clean and join your source systems and run feature engineering, with feature definitions shared between training and serving so the model sees the same inputs in production as in evaluation.
Text classification, entity extraction, and semantic search over tickets, contracts, or claims, built on spaCy and Hugging Face models and scored against a sample labeled by your review team, with accuracy reported per document type.
OpenCV and PyTorch pipelines for defect detection, document image classification, and product recognition, with an annotation plan and confusion-matrix review built into the first sprint, since label quality caps model accuracy.
Ranking and collaborative filtering models that personalize product feeds, search results, and offers for e-commerce and marketplace apps, tested through A/B experiments and reviewed by product owners before they take over live traffic.
Retrieval-augmented search, summarization, and assistants added to your product through generative AI integration, with prompt versions and retrieval quality scored against fixed test sets on every release, before it reaches users.
Pipelines that package models in MLflow, run CI/CD checks on every retrain, and deploy to SageMaker, Vertex AI, Azure ML, or Kubernetes, with instance sizing set against your inference cost budget.
Datasets are processed in your cloud project or a segregated workspace with role-based access and audit logs, and development runs on masked or synthetic samples where the use case allows. Raw records move only when needed, and deletion is confirmed at handover.
Trained weights, feature definitions, evaluation notebooks, and serving code arrive in your repository with a documented model registry entry, so another team can retrain or replace any component Citrusbug built.
Every release ships with an evaluation report covering precision, recall, and error slices by customer segment, and daily updates plus sprint demos let your team question results before they reach production.
For systems used in the EU, we identify applicable AI Act requirements during scoping. Article 50 transparency obligations apply from 2 August 2026, while Annex III high-risk rules apply from 2 December 2027, shaping the documentation, logging, and oversight planned into the system.
Share a real use case and representative data. Our engineers will assess data readiness, identify likely constraints, and give you a practical view of what machine learning can deliver.
Talk to an ML EngineerThe first budget commitment carries the most risk in any AI implementation, because nobody has yet tested the data or the metric the model will be judged on. Citrusbug runs a short feasibility phase that tests both before build scope is fixed.
Profiles volume, label coverage, missing values, and leakage risk across your sources, then rates data readiness for the target use case. Teams still deciding where ML fits can begin with an AI readiness discovery call.
Trains a simple baseline such as logistic regression or gradient boosting on a small sample to set the accuracy floor, so any later gain from deep learning or LLMs is measured against a real reference point.
Translates precision, recall, and latency targets into the price of a wrong prediction, for example, a missed fraud case versus a blocked genuine payment, so acceptance criteria are agreed before training.
Closes with expected accuracy, integration effort, inference cost, and regulatory exposure in one document, so you can approve the full build, adjust scope, or stop with the findings already recorded.
Repositories, cloud projects, and data connections are created in your accounts, with role-based access and a shared MLflow experiment log. Daily updates begin on day one, so your product owner sees progress in the same place engineers do, and questions about data definitions get answered before they can stall the first training run.
Engineers build ingestion, cleaning, and data annotation workflows in Spark or Airflow, with validation checks that fail loudly when a source changes shape. Datasets are versioned, so any model in the registry can be traced back to the exact records that trained it, which auditors and retraining jobs both rely on.
Each sprint trains candidates, then reports precision, recall, and calibration by customer segment, so weak spots show up before launch. Explainable AI output from SHAP or LIME goes to your domain experts for review, and sprint demos give your team a chance to challenge results while changing direction is still cheap.
Because Citrusbug also works as a machine learning app development company, the model ships as an API, batch job, or embedded service inside your web or mobile product. Latency budgets, autoscaling, and rollback are tested before release, canary traffic covers the first days in production, and each live version links back to its MLflow training run.
Live monitors track model drift by comparing incoming data and prediction distributions with the training baseline, and alerts route to a designated on-call owner. A retraining trigger agreed at launch decides when a fresh model is trained, scored against the incumbent, and promoted through the registry. GenAI features add retrieval hit rates and answer quality on a fixed test set.
The repository, runbooks, model cards, and registry access move to your team in a recorded walkthrough, and each production model has a documented retraining procedure with an owner assigned on your side. Post-launch L1, L2, and L3 support options cover incident response and scheduled retraining for as long as you want a partner on call.

You do. Trained weights, code, pipelines, and datasets transfer to your repositories at delivery, and Citrusbug works under NDA by default. Ownership terms belong in the contract before any data is shared.
Data pipelines, annotation, model training, evaluation, deployment, and monitoring, and any single stage can be contracted alone. Problem definition and final acceptance often stay with your team.
Builds commonly start near $10,000 for a scoped use case and can exceed $120,000 for multi-model production systems. Ongoing costs for retraining, monitoring, infrastructure, and support vary by workload and operating requirements. Data readiness, integrations, and compliance can also affect the total.
A feasibility review is short, and a first production model typically takes a few weeks to a few months depending on data readiness and integrations. Timelines are firmed up after the review confirms data access.
Drift monitors compare live data with the training baseline, and a retraining trigger agreed at launch promotes a new model only after it beats the current one on your test set.
Ask for the evaluation method, ownership terms, and a reference from a client of similar size, then run a short feasibility phase before committing to the full build.
Yes. Citrusbug holds ISO 27001 and SOC 2 credentials and follows HIPAA-aligned practices on healthcare projects. Regulated records can stay in your environment while engineers work against approved extracts.
