1) SUMMARY This year I focused on making our payments systems faster and more reliable while helping the team grow. I led the migration of the billing service to a new database with zero downtime, cut API response time from 800 ms to 300 ms, and mentored two new hires through their first 90 days. I also learned a hard lesson about planning on the search project, and I changed how I scope large work and share risks early. 2) KEY ACCOMPLISHMENTS - Led the migration of the billing service to a new database with zero downtime, so payments kept working throughout the switch. - Cut API response time from 800 ms to 300 ms, a reduction of more than half for the payments service. - Mentored two new hires through their first 90 days, giving them a steady point of contact while they learned our systems. 3) GROWTH AND LEARNING - Underestimated the search project timeline by six weeks, and I own that miss. - Now break big work into two-week milestones so delays show up early instead of near the deadline. - Flag risks early, which keeps my manager and partner teams informed sooner. 4) GOALS FOR NEXT PERIOD - Apply two-week milestones and early risk flags to every large project I lead next year. - Keep improving payments performance, building on the API response time work. - Continue mentoring new hires and share what worked in their first 90 days with the team. 5) MANAGER CONVERSATION POINTS - Ask which upcoming payments projects would benefit most from the migration experience. - Share the two-week milestone approach and ask for feedback on how it is working. - Discuss what a larger mentoring role could look like next year. - Confirm the top priorities for the next review period. 6) SELF-REVIEW CHECK Word counts: summary 77 words (range 60 to 90); accomplishments 3 bullets, growth 3 bullets, goals 3 bullets, conversation points 4 bullets; sections 1 to 4 total 223 words.
