As the Founder of FireWolf Studios, a forward-thinking software development consultancy, I lead transformative projects across legacy and modern application stacks, leveraging expertise in C, C++, C#, Python, and Java. My client-focused approach ensures tailored solutions that enhance system performance and deliver measurable outcomes.Currently, I am spearheading the modernisation of a legacy Medical Text Indexer (MTI), a pivotal tool used in medical research to semi-automate the indexing of biomedical literature. The MTI integrates complex algorithms such as natural language processing (NLP) and rule-based logic to assign Medical Subject Headings (MeSH)—a comprehensive controlled vocabulary critical for organising and retrieving biomedical information.This modernisation involves optimising the hybrid codebase in C and Java to improve processing efficiency and scalability while maintaining the tool’s high standard for accuracy and consistency. By fine-tuning the system’s underlying data parsing and indexing workflows, I aim to enhance the precision of MeSH term assignments, ensuring researchers can access relevant literature with unparalleled ease. This project exemplifies my commitment to bridging innovation and domain-specific challenges in the software development lifecycle.

● Delivered a performance enhancement to a major file processing component in C++ that reduced processing run time by 49.1%, cutting it from 5.3 hours to 2.7 hours per day. This optimisation also led to a 127% increase in system throughput, significantly improving overall efficiency. As a result the client was able to complete their migration journey on time saving them the potential of data center extensions which would have cost roughly £10 million per month.● Delivered a new bill enrichment and display solution in C++ and SQL (Oracle & DB2) that reduced execution times by 75%, decreasing it from 1 hour to just 15 minutes per day. This enhancement improved throughput by 292.2%, boosting the rate from 51 records per second to 200 records per second. Responsibilities: ● Developed high-volume, low-latency interfaces in C++, Perl and Java● Delivered enhanced and performance tuned ETL/ELT pipelines using Perl, SQL, PL/SQL and C++ with Oracle databases. ● Provided 24/7 front-line production support and collaborated with service management teams to resolve critical incidents. ● Worked as an Individual Contributor● Led the interface development team● Mentored junior developers, enforced coding standards, and led code reviews. ● Automated daily operations, saving 2 hours per day, and implemented 24/7 monitoring through a Node.js-based dashboard. ● Managed the migration of systems to IBM Cloud and ensured seamless performance during transitions.

Responsibilities:● Deployment, Setup and Configuration of the Geneva Billing Platform● The verification and fixing of defects on the Production system (running Geneva 5.0, Oracle 8i on AIX).● Day to day maintenance of the production and production support systems.● Liaising with customer for the application of patches to fix defects on the production system, and co ordination of the resolution of any defects.● Analysis, impact assessment, and delivery of changes required by the customer (O2) through the OSC (Operational Services Change) process.● Support of the development streams for future work.

Cambridge, England, United Kingdom

Responsibilities:● The verification and fixing of system faults. This included running application through such tools as PURIFY in order to locate these errors. And also liasing with other teams in order to ensure the most effective solution is implemented. This development work is all undertaken in the ansi 'C' language.● Enhancements to the GENEVA Billing Engine product on HP-UX, solaris and AIX using ansi 'C' and Pro 'C'.● Creating regression tests and test data to cover all requirements of any changes/enhancements, using PL/SQL and shell scripts.● Liason with other teams to ensure the enhancements and changes to the GENEVA product are implemented in the way they are intended, and to ensure these changes/enhancements meet all of the requirements in terms of functionality and quality.

C&DM Project :The Collection and Delivery Manager (C&DM) project integrates hand held PCs into the Post Office’s strategic Parcel management system (POISE).Responsibilities:● Participation in the data modelling and creation of the C&DM logical data model and its integration into the existing POISE logical model.● Liaison with IBM, the provider of the Hand held PCs for the provision of a POISE simulator, written as a number of thread safe Win32 functions written in C running under NT. This involved working against a pre determined Interface specification and a formal delivery mechanism. In addition to coding, the work involved input to the formal acceptance tests and support of the NT environments.● Production of specific C modules for the use of the Post Office's strategic CASE Tool, COOL:Gen, in accessing specific particular data structures or resolving performance bottlenecks, both within files and within the central Oracle Database.

POISE Project:The POISE Front End Processors are used to interface between POISE and the two Parcel Sorting systems. The interfaces supply and collect data on parcel traffic, vehicle movements and parcel delivery reference data. Communication is achieved via TCP/IP sockets. All components were running under HP-UX 10.20 accessing an Oracle 8.0.5 database via Pro*C.Responsibilities:● Migration of the existing interfaces from a previous version of Oracle to Oracle 8.0.5. ● Support and development of the Test Tools used to certify the Interfaces prior to their release to service. These test tools were a mixture of Oracle PL/SQL Packages and Microsoft Access SQL statements.● Prototyping automated testing tools for use in the formal acceptance of the 2 sorting systems. Written in Visual Basic running on an NT 4.0 workstation using an Access database, mapped onto the Front End Processors Oracle database. The prototypes were used to prove the concept of automated testing to the internal customer.
