Konstantin Kornilov

Biography

I am a software engineer with 16 years of professional experience in PDF and document processing technologies, working with established companies specializing in document-processing SDKs.

My background includes extensive work on fixed-page document generation in a DOCX processing SDK, primarily targeting PDF alongside other fixed-page formats, as well as more recent experience developing a general-purpose PDF processing SDK. This combination has given me a broad perspective on PDF technologies, from document generation and conversion to PDF internals, accessibility, conformance, and interoperability. I also have a strong background in font technologies and 2D vector graphics.

I am particularly interested in projects where deep PDF knowledge can help solve challenging technical problems, improve document processing quality, or support standards-based implementations.

Specialization

PDF technology and SDK development, document generation and conversion, PDF accessibility and tagging, PDF/A and PDF/UA conformance, and interoperability.

Complementary areas of specialization include font technologies and 2D vector graphics processing.

Capabilities

My primary focus is hands-on software engineering and the development of PDF and document processing solutions, including PDF generation and document conversion (particularly DOCX-to-PDF workflows), PDF SDK development, maintenance, and integration, as well as tagged PDF and accessibility-related implementation challenges.

My primary programming language is C#, but I am open to working with other languages and technology stacks depending on project requirements.

Availability

I am based in Spain and open to remote contract-based and consulting engagements, including short-term technical investigations, project-based development, and longer-term collaborations.
