Senior AI Engineer and Technical Advisor (Freelancer) at dialpad

Serving as AI technical advisor to Dialpad's Telephony Engineering division while building AI products hands-on. Currently developing MCP-based tooling for AI text and voice agents: agent authoring, integrations and adoption of existing agents, shared authentication and API contracts, and durable workflow state. This includes text and voice tests that evaluate agent behavior, latency and task completion.

In parallel, helping Dialpad's engineers adopt QualityLayer and use Claude Code and Codex effectively. This ongoing work covers context management for large codebases, reusable plan-implement-test-review workflows connected to CI/CD, playbooks, hands-on workshops, labs and pair programming.

Last position:

Platform Architect (Project lead) at Würth IT

I designed and built a self-service AWS platform for Data Science teams with little or no infrastructure-as-code experience. A team writes about 10 lines of Python and gets a deployable stack with full SDLC release cycle that already follows the governance rules. Networking, encryption, IAM and tagging are decided by the platform, not by each team.

New teams or AWS accounts are onboarded with one pull request. Waste prevention and cost control is built into the defaults: Data scientists don't need infrastructure skills.

  • Construct library (AWS CDK, Python). Built a versioned catalog of about 20 hardened constructs for being used in data-science projects with ML context
  • Governance as code
  • Multi-account, multi-tenant
  • Golden-path scaffolding
  • CI/CD and supply chain. Built reusable GitHub Actions workflows
  • Release engineering
  • QA with e2e, contract testing and unit test coverage with each release candidate

Last position:

Multi-Agent R&D Pipeline (3 Custom Agents) at Independent Project

  • Claude Code subagents, MCP, Pydantic V2, pytest, bandit

  • Designed and shipped 3 specialized agents that hand work down a line: a research agent writes a cited implementation spec, a coding agent builds the modular code and its tests, a review agent ranks findings by severity and applies the fixes. Each handoff is a structured document, so no stage depends on another agent's context window.

  • Connected the research agent to an academic-research MCP server (Semantic Scholar, ArXiv, Hugging Face Hub, citation snowballing) so every reference traces to a tool result rather than the model. Gated commits behind ruff, mypy, pytest and bandit, required human sign-off before installs and commits, and persisted session state on disk so long runs survive a context reset.

About the technology

What it does

Machine Learning enables software to learn patterns from data and use them to make predictions, classifications or decisions. Companies use it for demand forecasting, fraud detection, search, recommendations, language processing and image analysis. The work can support customer-facing products or internal operations.

Typical solutions

  • Predictive models for demand, churn, risk and maintenance
  • Recommendation and ranking systems for products or content
  • Computer vision for inspection, recognition and document processing
  • Natural language processing for search, extraction and support workflows
  • Anomaly detection for transactions, devices and operational data

Ecosystem and tooling

Machine Learning projects often combine Python with libraries such as scikit-learn, PyTorch, TensorFlow and XGBoost. Strong data preparation may involve SQL, pandas, Spark or cloud data services. Production work also connects models to APIs, containers, experiment tracking, model registries and monitoring systems.

When companies need experts

Companies bring in freelance specialists when internal teams lack model-building capacity, domain knowledge or production experience. They may need help turning an unclear business question into a measurable prediction task, improving an existing model, or moving a prototype into a dependable service. Short engagements can also add an independent review before launch.

What strong specialists deliver

Good professionals link technical choices to business outcomes. They define useful targets, check data quality, prevent leakage, select suitable evaluation methods and explain trade-offs clearly. They also consider latency, cost, security, fairness, retraining and how people will act on model outputs after deployment.

Signs of production readiness

  • Data pipelines are repeatable, documented and tested
  • Model performance is measured against a meaningful baseline
  • Training and serving environments produce consistent results
  • Monitoring detects drift, failures and changing data quality
  • Ownership, retraining and rollback processes are agreed

A reliable delivery includes more than a model file. It covers reproducible experiments, integration with existing systems, clear documentation and handover to the team that will operate the solution.

Frequently asked questions

Key details about Machine Learning, drawn from the questions we get asked most.

Machine Learning is used to find patterns in data and support predictions or automated decisions. Common applications include forecasting, recommendations, fraud detection, document processing, quality inspection and customer support workflows.

Machine Learning learns a model from examples, while traditional software usually follows rules written directly by specialists. It is useful when the rules are complex or change with the data, but it requires careful data preparation, evaluation and ongoing monitoring.

A strong Machine Learning specialist usually understands statistics, data engineering, software development and cloud deployment. Depending on the project, useful adjacent skills include SQL, Python, APIs, containerization, experiment tracking and model operations.

The right level depends on the task, data quality and production risk. A proof of concept may need focused modeling expertise, while a customer-facing system benefits from a professional who can handle data pipelines, deployment, monitoring and communication with business teams.

Machine Learning work is often suitable for remote collaboration because data, code and cloud environments can be shared securely. On-site work can help when specialists must access restricted systems, observe operational processes or work closely with teams handling sensitive data.

Before starting Machine Learning work, clarify the business decision, available data, expected output and constraints such as latency, privacy or integration. Access to sample data, subject-matter experts and a clear success measure helps a specialist assess feasibility quickly.

Look for evidence that the professional has taken models beyond notebooks into dependable products. Ask how they handle baselines, leakage, changing data, error analysis, explainability and monitoring, and whether they can describe trade-offs in terms your team can use.

Machine Learning projects commonly use Python with scikit-learn, PyTorch, TensorFlow or XGBoost. Teams may also use pandas, Spark, SQL, cloud services, containers and model-tracking tools, with the exact stack shaped by the data, model type and deployment environment.

The average hourly rate of freelancers who have used Machine Learning in their recent projects is 90 €, which corresponds to a daily rate of about 722 € based on an 8-hour working day.

Of the freelancers who have used Machine Learning in their recent projects, 97% hold at least a Bachelor's degree, 76% hold at least a Master's degree, and 18% hold a doctorate.

On average, freelancers who have used Machine Learning in their recent projects have 14 years of professional experience, with a single engagement typically lasting around 2.8 years.

The most common languages among freelancers who have used Machine Learning in their recent projects are English (98%), German (97%), and French (20%).
