Oliver Kirst
Last position:
Founder & AI Automation Architect at Zerobits
Zerobits is my vehicle for AI-powered automation and custom software development with a clear principle: AI solutions that reach production, not pilot stage. I design and build the systems myself - from first concept and architecture through implementation to deployment and operations.
My focus is on replacing repetitive, manual work with reliable automation and connecting disconnected tools and data sources into one dependable overall system.
Selected work:
- Design and implementation of LLM-based agent systems and RAG pipelines (Anthropic Claude, Mistral, MongoDB Atlas Vector Search + RAG)
- Workflow orchestration for long-running, fault-tolerant business processes using Temporal (temporal.io): saga patterns, event-driven architecture, retry and compensation logic, connecting third-party APIs and internal services into automated end-to-end processes
- Full stack product development: SaaS architecture on Kubernetes, TypeScript/React/NestJS, admin tooling with refine.dev and MUI
- AI-assisted development workflow as standard practice to deliver production software at a fraction of traditional timelines
- Full stack product development: multi-tenant SaaS architecture running on Kubernetes, backend with NestJS/Node.js and Python, frontend with TypeScript, React and Next.js, admin tooling with refine.dev and MUI, CI/CD with GitHub Actions
One of these projects is a product I own and operate - free of any NDA restrictions. I'm happy to demonstrate it end to end.

About the technology
Core use
Regular Expressions are a compact way to find, validate, extract, and replace text. Companies use regex in search, form checks, logs, routing rules, and data cleanup. It is the tool behind many everyday text tasks in software and data work.
Where it helps
- Validate emails, phone numbers, IDs, and file names
- Parse logs, CSV-like text, and event payloads
- Clean imported data before it reaches systems
- Build search filters, highlights, and token rules
- Support scripts, ETL jobs, and test automation
Ecosystem
Regex appears in many languages and tools, including JavaScript, Python, Java, .NET, Perl, grep, sed, and awk. Strong specialists know how each engine differs in flags, lookarounds, greediness, and Unicode handling. They also know when a parser is safer than a pattern.
Signs you need help
If your patterns are growing hard to read, breaking on edge cases, or slowing down releases, bring in a specialist. That is common in legacy code, data migrations, search tuning, and compliance checks. In Germany, teams often want clear documentation and clean handover so patterns stay maintainable.
What strong experts do
A strong professional writes patterns that are specific, testable, and easy to maintain. They name groups clearly, avoid catastrophic backtracking, and build examples for real input, not ideal input. They also review existing regex code and simplify it without changing the result.
Delivery focus
Regex work is often small in code size but critical in impact. Good specialists can join remotely, review existing patterns, and ship fixes quickly; on-site work helps when teams need workshop-style cleanup or shared decisions around text rules. For Germany-based teams, English is often enough for the patterns, but clear written comments matter.
Frequently asked questions
Quick answers to the questions that come up most around Regular Expressions.
Regular Expressions are used to match text patterns, extract values, and replace unwanted content. Companies rely on them for validation, log parsing, search, formatting, and data cleanup. They are small tools, but they often sit inside important business workflows.
Bring in a Regular Expressions specialist when patterns are hard to debug, when legacy code needs cleanup, or when text rules keep changing. Freelancers are also useful for short projects like migration support, search tuning, or validation hardening. They can focus on the tricky parts without slowing the rest of the team.
Regular Expressions are faster to write for pattern-based text tasks, but they are not always the safest choice. For simple validation and extraction, they work well; for nested or highly structured input, a parser is often better. A good specialist knows when to use regex and when to stop.
A strong Regular Expressions specialist usually also understands the language or runtime where the pattern runs, such as JavaScript, Python, Java, or .NET. They should know test design, text encoding, Unicode, and basic data handling. That mix helps them write patterns that work in real systems, not just in a test box.
A Regular Expressions project does not always need a large team, but it does need someone who has solved real edge cases before. Complex text rules, performance issues, and legacy patterns can become fragile very quickly. For mission-critical validation or parsing, proven pattern review skill matters more than volume of code.
Yes, Regular Expressions work is often a good fit for remote collaboration because most tasks are code review, rule design, and test cases. Germany-based teams often share patterns in tickets or pull requests, then review behavior with sample inputs. On-site sessions can help when many teams need to agree on one text standard.
Look for clear explanations, readable patterns, and careful handling of edge cases. A strong Regular Expressions expert will show tests, explain trade-offs, and point out where a parser would be safer. They should also be able to simplify old patterns without changing the business result.
Regular Expressions is the full term, while regex is the common short form and regexp is another variant you may see in code or documentation. They all refer to the same pattern-matching approach. The exact syntax still depends on the language or tool that runs the pattern.
