Mirza K.
Last position:
Agentic Automation and a RAG system
- This project involved extraction of intelligence data to support report writing for a company that provides geopolitical, global, commercial intelligence. The data have been gathered from a number of resources (interview transcripts, online data, internal documents), and then a knowledge base has been build from it. This was the basis of a complex RAG system, that was evaluated against a golden dataset. Agents have been used to find out the contradicting intelligence, the statements supporting each other, and to store back the generated knowledge.
Used: Python, RAG, LangGraph, LangChain, deepeval, MCP
Anthony M.
Last position:
Research and Development, AI for Enterprise at Mwanachama
- Built an MCP (Model Context Protocol) layer for Mwanachama's agency service, turning domain manager methods into callable AI-agent tools. This included a composite tool that builds a full organization design (org chart, goals, workflows, RACI matrix) from one specification.
- Built the chat-driven agency builder (Wakala Studio and API), where an organization describes its structure in natural language and an AI agent uses those tools to construct and modify the live design.
- Added an insights service so an organization can review AI-agent interactions and completed work. Insights from that review feed back into solution design, gated by architect and user sign-off.
- Alongside this, designed and built the platform itself: ~20 Go microservices on PostgreSQL, Flutter and React clients, deployed on Kubernetes.
- AI agents scan the platform autonomously for security gaps and run scripted tests, covering API (Postman-style) and UI testing. The rest of the work stays supervised. No rogue agents, promise.
- Building an AI-native enterprise platform that structures organizational data, workflows and responsibilities for both people and AI agents.
- Models accountability through RACI, allowing human and AI participants to take different operational roles, including Responsible, Accountable, Consulted and Informed. AI agents can also take controlled approval roles where the organization assigns that responsibility.
- Extended the organizational and operational-risk themes from my Executive MBA thesis into software, making roles, processes and controls explicit and machine-readable.
- Structures enterprise context so LLM interactions use more relevant information instead of repeatedly processing large amounts of unstructured content.

About the technology
What it does
A/B Testing compares versions of a webpage, feature, message or user journey with real users to measure which performs better against a defined goal. It replaces opinion-led changes with controlled evidence. The method is also called split testing or experimentation and can support conversion, retention, activation and revenue decisions.
Where it is used
Companies use A/B Testing across digital products and customer journeys:
- Landing pages, checkout flows and sign-up forms
- Product onboarding, navigation and feature adoption
- Email subject lines, offers and in-app messages
- Pricing presentation, search results and recommendation layouts
The right test depends on a clear hypothesis, a meaningful audience and a measurable outcome.
Tools and skills
A/B Testing specialists work with experimentation platforms such as Optimizely, VWO, Adobe Target, LaunchDarkly and Google Optimize alternatives. They connect tests with analytics and data tools including GA4, Amplitude, Mixpanel, Segment and data warehouses. Strong delivery also requires event tracking, audience targeting, feature flags, consent-aware implementation and statistical interpretation.
When to hire
Freelance expertise is useful when an internal team has ideas but lacks the capacity to structure, launch and evaluate experiments. It can also help when results are unreliable, tracking is incomplete or several teams need a shared testing process. In Germany, specialists may support local product teams on site or collaborate remotely across marketing, analytics and engineering functions.
Quality signals
A strong professional separates a hypothesis from a desired result and defines the primary metric before launch. They check sample quality, traffic allocation, test duration, novelty effects and overlapping experiments rather than declaring a winner too early. They document decisions, account for implementation limits and explain uncertainty in language that product and commercial teams can use.
Project outcomes
Typical deliverables include an experimentation roadmap, opportunity research, tracking specifications, test variants, platform configuration and QA plans. Specialists may also create dashboards, analysis reports and a repeatable decision framework for future tests. For teams working in Germany, clear English or German communication can help align stakeholders, agencies and remote contributors around the same evidence.
Frequently asked questions
Everything clients usually want to know about A/B Testing, in one place.
A/B Testing is used to compare two or more versions of a digital experience against a defined objective. Companies apply it to conversion flows, onboarding, product features, messaging, pricing presentation and other measurable user interactions.
A/B Testing usually isolates a change or compares complete variants, making the result easier to interpret. Multivariate testing evaluates combinations of several changes and generally requires more traffic and a stronger experimental design.
A strong A/B Testing specialist may work with Optimizely, VWO, Adobe Target, LaunchDarkly or another experimentation platform. They should also understand analytics systems such as GA4, Amplitude or Mixpanel, plus tagging, feature flags and data quality checks.
An A/B Testing professional often needs product analytics, conversion research, UX evaluation, copy testing and event tracking skills. Knowledge of SQL, JavaScript, experimentation statistics and consent-aware measurement can also be important.
The right level for A/B Testing depends on the scope, traffic quality, platform and business risk. A focused test may need a specialist who can structure the hypothesis and implementation, while a wider programme benefits from someone who can govern the backlog, metrics and decision process.
Yes, A/B Testing work is often suitable for remote collaboration because research, configuration, QA and reporting are digital. Teams in Germany should agree on working language, access to analytics and testing systems, meeting routines, and who owns final product decisions.
Ask how the A/B Testing specialist defines a hypothesis, selects a primary metric and handles inconclusive results. Good professionals can show how they validate tracking, check audience allocation, document limitations and prevent teams from overreacting to early signals.
A/B Testing measures how defined variants perform in a live context, while user research helps explain needs, motivations and usability problems. The methods work well together: research can generate hypotheses, and testing can assess which evidence-backed change improves the chosen outcome.
The average hourly rate of freelancers in Germany who have used A/B Testing in their recent projects is 86 €, which corresponds to a daily rate of about 685 € based on an 8-hour working day.
