October 2025 monthly summary for trade-tariff/trade-tariff-lambdas-fpo-search: Focused on delivering higher quality trade data processing, strengthened search capabilities, and hardened deployment practices. Key features delivered include automated sampling of trade statistics with a Gemini LLM classifier (with confidence/reasoning outputs and robust fallback if LLM calls fail), and expansion of FPO reference data with new goods descriptions and commodity codes to improve searchability. Upgraded the fpo-search-model-generator to v1.19.0 to enable the latest model generation improvements. Hardened deployment workflows by removing SCP credentials across development and staging, reducing credential leakage risk. Addressed stability issues in the codebase with fixes to Map2024CodesTo2025Codes.build initialization and the training data loader API consistency, enhancing reliability of the training pipeline. These efforts contributed to improved data quality, faster and more reliable classifications, stronger security posture, and a more maintainable codebase in support of HMRC-facing search and classification services.

September 2025 performance summary for trade-tariff development. Delivered key user-facing updates, stability improvements, and ML/infra enhancements across frontend and search-lambda services. Focused on business value through clearer guidance, improved accessibility reliability, stronger data and model integrity, and scalable infrastructure readiness for next release.

August 2025 monthly summary: Delivered user-facing frontend improvements to the Exchange Rates page, enhancing clarity of currency application and removing an NI-specific paragraph to reduce user confusion. Implemented accessibility and UI polish on the frontend (alt text for calculator image and improved basic session UI) to improve usability for assistive tech and overall UX. Fixed a critical routing issue by correcting the exchange rate data redirect file suffix. In the Lambda-based FPO search work, added TRACE support on getmodel, stored and surfaced benchmark details for easier comparison, and enhanced benchmark checks for deeper diagnostics. Expanded model capabilities with vague-terms support, a new model version, and quantized model integration to improve performance and inference efficiency. Strengthened developer experience with robust pre-commit tooling, Ruff validation, and build optimizations, plus improved Slack notifications for faster collaboration. Overall, these changes increased reliability, reduced support overhead, and accelerated delivery of model-driven features with measurable business impact.

July 2025 monthly summary focusing on key accomplishments across the two Trade Tariff repositories. Highlights include deployment reliability improvements, AWS cost optimization, and CI/CD/QA enhancements that strengthened security, performance, and developer efficiency.

June 2025 performance summary: Delivered cross-stack features and reliability improvements across two repositories, focusing on business value and technical excellence. Key outcomes: - Duty Calculator delivered across the trade-tariff-frontend (front-end JS, routes, controllers, models, decorators, views, locales, services, link helpers, configuration, specs, lint, setup) with a new service-selection method and layout cleanup. - Workflow and bot enhancements: simplified triggers, bot user configuration, emoji and favicon added, and skip history behavior. - CI/CD and workflow efficiency: DRY’d workflows by reusing a shared workflow and simplified CI configuration. - Development reliability and maintenance: introduced schedule-based stop of development services and disabled tests in development; upgraded Ruby to 3.4.4 and updated UKTT; moved development dependencies and ensured services start during development. - Quality and stability: fixed broken page titles, fixed an unclosed HTML tag, and resolved search model generator version regression by reverting to 1.11.3.

Month: 2025-05 Key features delivered: - trade-tariff/frontend: CI/CD enhancements integrating Playwright and Axe accessibility tests, refined deployment triggers, and reduced notification noise. - trade-tariff/frontend: Test and infrastructure cleanup with standardized Terraform/development formatting for reliability. - trade-tariff/lambdas-fpo-search: CI/CD workflow security and automation enhancements — tightened permissions, refined PR automation, and consolidated production/dev notifications. - trade-tariff/lambdas-fpo-search: Dependency updates (e.g., torch) to maintain compatibility. - trade-tariff/lambdas-fpo-search: Sentry removal and secrets cleanup to reduce surface area. - trade-tariff/lambdas-fpo-search: Removed perftest step from deployment pipelines to streamline Dev/Staging. Major bugs fixed: - XI client path prefix routing: configurable path prefixes to ensure XI client requests reach the correct backend, preventing misrouting to UK. - Exchange rates backend domain in links: prepended BACKEND_BASE_DOMAIN to file paths to ensure correct backend downloads. Overall impact and accomplishments: - Increased deployment reliability and accessibility compliance; reduced noise and maintenance overhead; improved security posture by limiting token permissions and removing Sentry. Ensured correct routing and data sources across frontend and lambda deployments. Technologies/skills demonstrated: - Playwright and Axe accessibility testing, CI/CD automation, PR automation, permission hardening, secret management, dependency management, and infrastructure formatting (Terraform).

April 2025 monthly summary: Delivered a set of frontend authentication, CI/CD modernization, deployment reliability improvements, and codebase refinements across trade-tariff/frontend and lambdas-fpo-search.
