What I actually work with

Nine years across backend, frontend, payments, and infrastructure. These aren't things I've read about they're what I use on real projects, under real deadlines.

Backend & Architecture

Primary: .NET 8 / C# / EF Core / SQL Server

.NET / .NET 8 C# EF Core SQL Server REST APIs Microservices Kafka MongoDB Background Jobs

Production-hardened

Idempotency, audit logs, error handling, monitoring-ready from day one.

Multi-tenant SaaS

Org-scoped data, role-based access, secure isolation I know where the edge cases hide.

Frontend, CMS & Delivery

Primary: React 18 / TypeScript / Tailwind

React 18 TypeScript Tailwind PHP Laravel WordPress SEO Bootstrap AG Grid Syncfusion

Built for real users

Accessibility, responsive design, information architecture that actually makes sense.

Ships clean

Optimized assets, Core Web Vitals, deploy-friendly from the start.

Payments & Integrations

I've built payment flows that handle real money tokenization, webhooks, idempotency keys, failed payment recovery, and cross-gateway reconciliation. Five processors, zero shortcuts.

How I can help

I don't take on work I can't own. Every engagement gets clear milestones, honest communication, and code your team can actually understand later.

Build

SaaS Platforms

You need a product that works for 10 users today and 10,000 next year with different roles, permissions, and data that never bleeds across accounts. I've built this in housing platforms, marketplaces, and logistics tools. I know where the edge cases hide.

Pay

Payment Systems

Payment integration is not just adding a Stripe button. Webhooks fail. Duplicates happen. Reconciliation breaks. I've handled all of it across Stripe, PayPal, Square, ACH, and USAePay in the same product.

Secure checkout · idempotency · reporting · audits

Ship

Websites & SEO

Fast, well-structured websites that rank and convert. WordPress or Laravel, built for real performance not just a pretty theme. Core Web Vitals optimized before handoff, not as an afterthought.

Laravel · WordPress · schema markup · speed tuning

Fix

Performance & UX

Slow systems, flaky APIs, or UX that confuses users. I audit first, fix the real cause, then measure. Not guesswork. I improved system stability by 35% on one project through structured reviews and coding standards alone.

Audit → root cause → fix → measure

What clients say

Feedback from the people I've worked with across SaaS, payment, and web projects.

How I work

1. Understand the problem

I don't touch code until I understand the real requirement not just the stated one.
2. Build in slices

Ship working pieces early. Real feedback beats perfect planning every time.
3. Harden before launch

Security, edge cases, performance, monitoring. Not an afterthought part of the build.

Building in public

Things I've learned the hard way on payments, SaaS architecture, and engineering leadership. No theory. Just what actually happened on real projects.

Webhook reliability and idempotency in production

Payments

Webhook reliability: idempotency that actually works

How I stopped duplicate charges from happening in a multi-gateway payment system and the pattern I now use on every new integration.

SaaS

Multi-tenant filtering in .NET (without performance pain)

The approach I use to keep org-scoped data isolated without hammering the database drawn from building three separate multi-tenant platforms.

WordPress speed wins: the checklist I actually use

Not another generic plugin list. These are the specific fixes that moved the needle on Core Web Vitals for real client sites.
