Here are examples of a payment-checking improvement and two personal software projects. Each explains what I did, the results so far and what still needs work.

I'm Mark Jay Lisay. I work in Accenture's Accounts Receivable department, which handles records of money owed and received. I check insurance payments against bills for businesses and their individual members.
Each month I manage about 130 business accounts and investigate 30–100 payment differences. I use Excel to find the cause of those differences. One tool I built saved more than five hours on an unusually complex task.
I also helped three small Philippine businesses with QuickBooks Online: recording money owed and received, preparing bills, checking bank records and preparing financial reports. Alongside this work, I build personal software projects with help from AI and review the results myself.

Checking insurance-payment records, meeting work targets and reducing repetitive tasks at Accenture.
I check payments for businesses and their individual members.
Average annual score from quality checks of my work.
Performance measured against the service targets agreed for my work.
Saved on one complex task using an Excel tool I built.
Checking individual members’ payments involved many repeated steps. I built an Excel tool to match payments that met the rules and leave records needing attention for a person to review.
Saved on one unusually complex payment-checking task.
The tool handled repeated matching steps. A person still reviewed payments that needed a closer look.Also recognized as Top 1 Agent and Top Performer for two months in 2023, with 100% performance and quality-check scores during that period.
My main skills are checking payment records, keeping books in QuickBooks and improving spreadsheets. I also build personal software projects with help from AI.
Check payments against bills and investigate differences in business and individual member records.
Record money owed and received, prepare bills, compare bank statements with the books and prepare business reports.
Use Excel to summarize data, find matching records and reduce repeated steps. VBA lets me build tools that do those steps automatically.
Report progress, record problems clearly and work toward agreed quality and service targets.
Find slow or repeated steps, try a simpler approach and check the results with a person’s review.
Plan what a tool should do, give tasks to AI tools, review the results and check that features work before release.
I use ChatGPT, Claude Code, Codex, OpenCode, Gemini and OpenRouter to help plan and build projects, then review their output. I write clear instructions for these tools. I also use n8n and webhooks to connect apps and pass information between them.
I use Git and GitHub to track code changes, GitHub Actions for repeated project checks, and VS Code to edit code. Hosting and data tools include Azure, Vercel, Cloudflare, Supabase/PostgreSQL and Turso. I use Firebase Test Lab to check apps on different devices. My Docker knowledge covers the basics of running projects in separate environments.
I have basic knowledge of Python and TypeScript/JavaScript, which are programming languages. I also know HTML/CSS for web pages and have experience with FastAPI, Next.js concepts and Node.js for building apps. JSON and REST APIs let apps exchange information. I plan tests, record problems and check that changes keep existing features working.
In Excel, Power Query cleans and combines data, PivotTables summarize it, XLOOKUP/VLOOKUP find matching records, and VBA handles repeated steps. I use QuickBooks Online for bookkeeping and compare financial records to find differences. FFmpeg helps process video and audio files, and I organize these tools into repeatable steps.
I have four years of experience at Accenture and now check payment records in its Accounts Receivable department. My bookkeeping projects and earlier healthcare roles are below.
