Backend - Infra & DevOps Lead

02/2019 - Present

Reporting to the VP of Software Engineering. Held this leadership role continuously since 02/2019, latterly under the current title.

• Lead the Backend, Infrastructure and DevOps function. Four engineers report to me across three disciplines and I own their performance evaluations; of five positions, one is vacant after an exit I decided and carried through.
• Took over the company's identity and access platform in 2019 — the single sign-on provider for a product serving 18 enterprise customers — and have been its principal contributor since: the authorization server, the admin API, the user-management front end, federation with external identity providers, and the multi-tenant claim model. My share has risen from 30% of its history to 43% over the last three years.
• Designed how autonomous agents are authorized on the platform: delegation rather than impersonation, so an agent acting for a person carries a readable record of who delegated to it, cannot exceed that person's rights, and stays inside one customer's data at the moment it acts. Built, tested and working; the last audit found nothing exposed in production. The surrounding agent platform was built with the team.
• Absorbed two specialist functions as they were vacated, neither with added headcount: production database ownership for every customer-facing server and database — backup and recovery strategy, index maintenance, capacity — and the test and CI function.
• Modernized the identity stack across every system that consumes it. Where a dependency could not be patched, accepted the residual risk in writing, with a mitigation and a review trigger.
• Core maintainer and release gatekeeper of the company's job-orchestration platform, and integration owner for an ETL estate of 80+ integration modules.
• Own a multi-region AWS, source-control and CI estate, including a self-hosted CI runner fleet.

Senior .NET Developer

05/2014 - 02/2019

• Founded the dashboard API platform — its first commit is mine (03/2017) — and remain its top contributor of 29 after contributing in ten consecutive years: 54 projects and 23 pluggable data-access adapters over SQL Server, MySQL, MongoDB, Elasticsearch, CloudWatch, GIS, Jira and run-management back ends.
• Designed the platform's tenant isolation: a separate data connection per customer and environment, resolved from the caller's token at request time, with a customer discriminator applied across the shared control plane.
• Top contributor of 49 to the customer-facing planning web application, with commits in every calendar year from 2014 to 2026.
• Originated the event-monitor Windows service that still runs the platform's scheduled workflow, scenario and notification jobs.

.NET Application Developer

02/2013 - 05/2014

• Built the Google AdWords API integration project; developed and maintained client applications across a multi-project delivery portfolio.

.NET Application Developer

01/2011 - 02/2013

• Delivered web applications for financial-services and global consumer brands — Akbank, Garanti, İş Bankası, Denizbank, the Interbank Card Centre (BKM, NFC), Volkswagen, Mercedes-Benz and Microsoft — taking requirements directly from clients, including on-site work, across several concurrent accounts.
