How we solve hard language engineering problems

Real projects across finance, aerospace, retail and software — parsers, migrations and blueprints that moved critical systems forward.

Migration Blueprint

Legacy Codebase Migration Blueprint

1.9 million lines of IBM EGL moved toward Spring Boot, for a pension fund manager handling €590 billion. Five workshops turned an unmapped codebase into a module-by-module plan, at a guaranteed price. CGI is a Strumenta partner.

Strumenta’s methodical process and attention to detail stand out.Paulo Jorge Dias, Director Consulting Expert, IT Modernization, CGI

Parser Modernization

ANTLR Parser Modernization for EXPRESS

A new ANTLR 4 grammar for EXPRESS (ISO 10303-11), replacing a parser built on ANTLR 2 — unsupported since the mid-2000s — while keeping the generated code compatible. Delivered with a 90-day warranty.

I wouldn’t have been able to do this in the time Strumenta did – probably not even in 3 times the time!Duncan Gibson, Software and Space Thermal Engineering support, ESA TEC-MTV

Parser Development

SQL Parser Support for International Expansion

Two parsers to identify the tables and columns buried in Vertec’s SQL, so a Swiss PSA product with 1,200+ customers across Europe could be translated out of German. Vertec PSA now ships in English.

If someone needs to build a parser or compiler, then Strumenta is really the place to go.Samuel Iseli, Co-founder, Vertec

Migration Blueprint

RPG to Python Migration Blueprint

IBM AS400 RPG written from the 1970s onward and still critical to the business, mapped module by module for a move to Python. Their IT manager found Strumenta through a Google search and concluded it was the only company that could automate an RPG-to-Python migration.

If you need to migrate your RPG code to Python, give Federico a call.Kay Litchfield, IT Manager, David Nieper
