Experience
- Built an AI audio-audit pipeline on AWS S3 and SQS to process 2K+ call recordings daily, using GPT-4o-transcribe for transcription and LLMs to score calls against quality rubrics.
- Improved audio-audit score consistency across OpenAI, Groq, and Gemini by 48% using consistent model settings and strict JSON outputs, while increasing AI confidence-rating coverage from 40% to 80%.
- Debugged and fixed 10+ silent bugs causing incorrect or missing audit scores, tracing each one through PostgreSQL data checks and validation.
- Built a feedback pipeline for agents across 12+ enterprise customers, delivering daily, weekly, and monthly insights linked to supporting audio clips and transcript quotes.
- Built (goodluck.services) a responsive education and migration consultancy website with a centralized admin dashboard for managing content and business operations.
- Optimized the website for international visitors on mobile and low-bandwidth networks by reducing image payloads, unnecessary JavaScript and animation overhead, improving loading speed and scrolling responsiveness on resource-constrained devices.
- Improved production efficiency and reliability by eliminating unnecessary database data retrieval, reducing homepage database round trips, preserving cached pages during database failures and enabling CMS content updates without full application rebuilds.
