Senior Software Engineer, AI

Built and maintained Python and TypeScript backend services and LLM-powered capabilities for Atlassian cloud products used by enterprise teams. Designed permission-aware RAG pipelines that enabled AI features to answer from customer pages and tickets.

Created an LLM evaluation harness using curated test sets and automated scoring that became a release gate for AI features. Improved p95 REST API latency by about 40% through NoSQL index improvements, Redis caching, and redundant-call removal, while reducing LLM inference costs by roughly 30% through prompt optimization, response caching, and model routing.

Mentored four engineers, led design reviews, reduced noisy on-call alerts, and partnered with designers, product managers, and data scientists to take AI products from prototype through launch.

Built fraud detection models using transaction data, gradient boosting, and anomaly detection to improve fraud detection while controlling false positives. Developed customer behavior and recommendation models to help product teams target offers and cross-sell financial services.

Delivered Python REST APIs that served model scores to payment flows in real time. Automated transaction reconciliation and financial reporting pipelines, reducing manual spreadsheet work and shortening month-end close.

Implemented model monitoring for data drift and accuracy to identify production issues before they affected customers.

Delivered analytics and data science projects for finance, retail, and service-sector clients. Built SQL and Python dashboards, KPI reporting, sales forecasting, cash-flow forecasting, and budget-versus-actual variance analyses for leadership decision-making.

Cleaned and modeled financial data from general ledger, AP, and AR systems for reporting. Developed backend Python services and ETL jobs to reliably move data between client systems.

Built responsive websites and web applications for small and mid-sized business clients using JavaScript, PHP, and MySQL. Developed invoicing and inventory modules, applying accounting knowledge to maintain accurate financial records.

Fixed software defects, wrote tests, and participated in code reviews with senior engineers. Contributed to client-facing web solutions across the development lifecycle.

Concentration in Accounting and Finance. Relevant coursework included Financial Accounting, Cost Accounting, Auditing, Accounting Information Systems, Database Systems, and Systems Analysis and Design.
