About this gig
Send me the bug. You get the fix, the cause, and a plain-English explanation you can check same day for most issues.
I do not patch symptoms. You get told what was actually wrong and why it happened, so it does not come back in a different shape next month.
I fix:
API errors, 500s, crashes, exceptions, memory leaks
EF Core, SQL Server, PostgreSQL query and migration issues
Angular and React errors, build failures, broken UI logic
Authentication bugs (JWT, Identity, OAuth2)
Stripe, PayPal, and Twilio webhook and payment issues
Deployment and CI/CD failures on Azure, AWS, Docker
What you get with every fix:
The root cause named, not just the symptom gone
A short write-up of what was wrong, in plain language
The exact files changed, listed, so your team can review it
Same-day delivery for urgent issues
Why me: Senior Software Engineer, 9+ years in enterprise .NET healthcare SaaS, ERP and payroll, airline booking, IoT platforms. 5.0 rated here.
Send the error before ordering. If I cannot fix it, I tell you before you pay you risk nothing.

English
Nine years of .NET and Angular, now with AI agents on top. I started by fixing production bugs in enterprise SaaS. Then I built my own products: a meeting transcription SaaS live and selling in 16 days, and an agent platform where a coding agent pauses and asks a human before it guesses. Four gigs, one engineer. I fix your ASP.NET Core or Angular bug and explain the cause. I build WhatsApp and voice agents that answer from your data. I build programmatic SEO sites that index. Send the repo or the spec. You get a clear reply within hours.

FAQ
Can you help convert Figma designs?
Yes, I offer full Figma to Angular conversion (clean HTML/CSS). Many prefer it over figma to React due to performance and structure.
Do you work on existing Angular/React codebases (bug fixes & components)?
Yes. I can fix build/runtime errors, refactor code, or add new components/pages with clean TypeScript.
Can you convert Figma/XD to Angular Material, Tailwind, or React (MUI)?
Yes, pixel-perfect, responsive UI with Material/Tailwind/MUI, including forms, routing, and validation.
Do you integrate APIs (REST/GraphQL/Firebase) and handle auth?
Yes. I implement services, interceptors, error handling, JWT/OAuth flows, and secure API calls.
Front-end only or full-stack?
Front-end only. I integrate your existing backend/APIs and collaborate with your team if needed.
Can you optimize performance/Core Web Vitals?
Absolutely lazy loading, code-splitting, image optimization, caching strategies, and Lighthouse checks.
Do you support Angular/React upgrades or migrations?
Yes. I upgrade Angular projects to the latest stable and migrate legacy React/CRA to Next.js when requested.
When do you use NgRx or Redux Toolkit?
Only when state is complex (shared, asynchronous, or cached). Otherwise I keep it lightweight.
Can you build dashboards/CRMs with charts, tables, filters?
Yes—admin panels with pagination, search, sorting, and charting libraries (e.g., Chart.js/Recharts).
Do you handle deployment?
Yes (as an extra). Vercel, Netlify, Azure Static Web Apps, or S3/CloudFront with environment configs.
