Hi, I'm
Carsten.

Carsten Kraft
LinkedIn Profil

I'm a German IT Consultant & Software Developer with over 25 years of hands-on experience building enterprise systems, PKI infrastructure, B2B platforms, and digital products — from Stuttgart to Manila and everywhere in between.

My deepest specialisation is in PKI and certificate lifecycle management. At m2trust / eCom Service IT GmbH I work as a developer and consultant on an enterprise PKI administration platform serving large enterprises and government agencies. My work spans the full platform — enrollment services and protocol translation (ACME, SCEP, CMP, EST, XCEP/WSTEP, and the m2trust native REST enrollment API for Enrollment Agents on Windows, Linux, and Mac), Infrastructure Services, Device Management Services, User Portal, and the Core Admin Web — covering all backend systems and databases, continuous feature development, bug fixing, and the complete Azure-based development pipeline. Stack: C# .NET Core · Azure · MS-SQL Server · Angular · Linux.

Continuous learning is my life. I'm currently exploring local AI / LLM integration using Ollama, LangChain, and open-source models — building practical AI expertise to complement my enterprise background.

Alongside consulting I run three established blogs — TechCrates.com (EN), TechUni.de (DE), and StudentLifeOnline.org (EN) — all registered around 2010 and continuously publishing ever since.

Available for software development, PKI consulting, and AI integration projects.
