I build and maintain ERP, POS, CRM, and e-commerce systems with a strong focus on backend logic and data reliability. I work with Next.js, React, Golang, Ruby on Rails, Laravel, and Symfony, and I specialize in improving existing production systems rather than pushing full rewrites.
FAQ
How long does it take to build an eCommerce app/ERP system?
A: Most projects ship in 7-14 days, depending on complexity. For example: A basic MVP (logins, cart, home page): 7-10 days ERP with custom APIs + payment gateways: 10-14 days I’ll share a detailed timeline within 24 hours of discussing your requirements!
Do you offer revisions after delivery?
Yes! Each package includes 1-3 free revisions to ensure the final product aligns perfectly with your vision. Need more tweaks? I offer affordable post-launch support plans.
Can you integrate [XYZ] API or payment gateway?
Absolutely! I’ve worked with Stripe, Razorpay, Shopify, and custom APIs. Just share your preferred tools, and I’ll handle the technical heavy lifting.
Will I own the source code after delivery?
100% yes. You’ll receive full ownership of all code, databases, and design assets. I also provide documentation for easy handover to your team.
Do you provide maintenance after deployment?
Yes! My Premium package includes 3 months of free maintenance (bug fixes, server updates). Ask about affordable monthly plans for long-term support.
Can you publish my app to the Play Store/App Store?
Of course! I’ll handle store submissions, screenshots, and policy compliance (add-on service available). Check my portfolio for published apps like Eden Lounge.
What if I need changes mid-project?
Flexibility is key! I’ll provide weekly updates, and you can request changes anytime. Small tweaks are free; major pivots are billed hourly at a discounted rate.
