About

API Integrations

I specialize in connecting business systems — QuickBooks, Stripe, Zoho, and more — so your data flows automatically without manual effort.

Business Dashboards

I build real-time dashboards that surface the data your team actually needs — invoices, customer activity, sales performance — in one clear view.

Workflow Automation

I design automation tools and AI-assisted workflows that eliminate repetitive tasks, reduce manual tracking, and help businesses scale efficiently.

Who I Work With

Problems I Solve

Clients don't hire technologies — they hire developers who understand their specific problems. Here's what I help businesses fix.

"We use QuickBooks but can't see our data clearly"
Businesses using QuickBooks that need better visibility into sales, invoices, and customer activity — without constantly logging in and manually building reports.
"We're still tracking everything in spreadsheets"
Teams that need proper internal tools to replace fragile spreadsheets — reliable, role-based software built around how your business actually works.
"We waste hours every week on manual follow-ups"
Companies that want to automate repetitive workflows like invoice reminders, customer follow-ups, and status reporting — so their team focuses on real work.
"We need one dashboard for all our business data"
Companies that need custom dashboards to track KPIs, customer activity, and sales performance — all in one place, connected to the systems they already use.
"We want to add AI but don't know where to start"
Businesses looking to integrate AI into their workflows practically — not flashy demos, but real tools that draft emails, summarize data, and surface insights automatically.
"Our business tools don't talk to each other"
Teams that rely on multiple platforms — accounting, CRM, ecommerce — that need to be connected so data flows automatically between systems without manual syncing.

If any of these sound like your business, let's have a conversation.
