    About

    From core banking to AI agents

    15+ years in enterprise integration, currently at Birlasoft.

    I started in 2009 at Oracle Financial Services, building core-banking integrations with Oracle SOA, OSB and ODI. Since 2014 I've been at Birlasoft, growing from consultant to solution architect. Today I lead the middleware and BPM tower for a Fortune 500 energy-sector client.

    Most of my work is modernization: moving 300+ legacy SOA and OSB integrations to Boomi, cutting licensing costs, connecting three ERPs to 50+ systems, and taking e-invoicing live in six countries. I care about integrations that are still simple to support years after go-live.

    I also build AI agents and MCP tools that connect models to real APIs and data, and write about them here. It keeps me hands-on with where software is heading.

    Migrating 300+ integrations from Oracle SOA to Boomi

    A large estate of legacy Oracle SOA and OSB integrations was carrying growing technical debt and licensing costs.

    • Led the migration of 300+ legacy SOA and OSB integrations to Boomi, with API management on Axway.
    • Built reusable Boomi components, including one for consuming SOAP APIs, to keep the rebuilds fast and consistent.

    The legacy SOA estate was retired, cutting technical debt and licensing costs.

    Cutting Boomi licensing with SOAP over REST connections

    Every SOAP service called through its own Boomi connector added to the connector licence count, so licence spend grew with each new endpoint across a large integration estate.

    • Designed a reusable component that builds the SOAP envelope and calls the service through a REST connection.
    • Standardized it so teams could call new SOAP services without adding connectors.

    Significant annual licensing savings for the client, with no change to the services being called.

    E-invoicing across three ERPs and six countries

    Tax authorities in several countries require invoices to be submitted electronically, each with its own format and channel, while the client's invoices originate in three different ERPs.

    • Built direct government integrations for Argentina and Mexico.
    • Routed Poland, France, Malaysia and the UAE through a central tax-compliance platform.
    • Used one integration pattern across all three ERPs, so adding a country doesn't mean three separate builds.

    Compliant electronic invoicing in six countries from all three ERPs.

    Running a middleware tower of ~3,000 integrations

    About 3,000 integrations and APIs across Boomi, Axway, Oracle Integration Cloud, ODI, Oracle SOA/OSB and BPM, connecting three ERPs, Dynamics 365 and 50+ other systems.

    • Lead a ~40-person onsite and offshore team through six leads, covering application support and new projects.
    • Run quarterly PI planning for the tower and act as the escalation point for the hardest problems.
    • Introduced Git-based CI/CD for Oracle Integration Cloud with GitHub Actions.
    • Leading the move from Oracle BPM to Bizagi, starting with three new processes.

    One team running day-to-day support and new integration projects across the whole middleware estate.
