+Hello OpenStack Community,
+
+I am writing to submit my candidacy to be the PTL for the OpenStack-Helm project
+for the 2026.1 cycle.
+
+## Achievements in 2025.2
+Although the release cycle is not yet complete, we can already highlight some points
+
+### Loci
+- Cleaned up outdated customizations
+- Cleaned up Centos related files
+- Added images Blazar, Freazer
+- Mount requirements image instead of fetching wheels via HTTP
+- Use Opendev Infra APT mirror
+
+### Openstack-Helm-Infra retirement
+It's been a while since we started episodically discussing the merger of
+Openstack-Helm and Openstack-Helm-Infra repos and eventually decided to implement
+this to make it easier to implement/test things involving infra charts.
+
+### New charts
+- Skyline (merged)
+- Watcher (merged)
+- Blazar (on review)
+- Freazer (on review)
+
+### Tests
+- Implemented VXLAN overlay networking in test environments to address issues
+  when test nodes are in different L2 segments. This has improved stability and reduced rechecks.
+- Use pre-commit for linting. The pre-commit framework supports many languages and provides
+  various checks that can be easily run on a local developer machine.
+- Added an **Octavia** test case. Currently, it tests only the Amphora driver;
+  OVN driver tests are planned for a future update.
+
+### Ingress
+We are on the way of improving the Ingress object management. At this point we've
+changed all the test jobs to use Metallb as a frontend for the Ingress controller
+eliminating the need for a so-called `cluster ingress`. By the end of 2025.2,
+we aim to simplify Ingress management across all charts.
+
+### Granular service accounts
+- For core services (**Nova**, **Placement**, **Neutron**, **Glance**, **Cinder**),
+  we introduced dedicated service accounts for inter-service access (e.g., `nova_neutron`,
+  `nova_placement`). This approach improves security and flexibility.
+- Service account configurations have been split into dedicated files (e.g., Nova’s
+  service accounts are now defined in `/etc/nova/nova.conf.d`), which are automatically
+  included by `oslo.config`.
+
+I would like to sincerely thank all our contributors and users for their continued support.
+I look forward to further fruitful collaboration.
+
+It would be an honor to continue serving as PTL, and I am eager to keep pushing the further
+project's growth and innovation.
+
+Best regards,
+Vladimir Kozhukalov
