UNCOMPROMISING STANDARDS
Why High-Growth Teams Choose CodexEngr
How working directly with a senior full-stack architect compares to the typical hiring alternatives.
| Criteria | Muhammad (CodexEngr) | Traditional Agency | Marketplace Freelancer |
|---|---|---|---|
| Delivery Velocity | 2 to 4 weeks (focused sprints) | 3 to 6 months (bureaucracy) | Unpredictable delays |
| Direct Communication | Direct 1-on-1 with Muhammad (Daily async) | Filtered through account managers | Sporadic / timezone ghosting |
| Codebase Quality & Typing | Production TypeScript, clean architecture & modularity | Mixed quality / junior devs assigned | Quick hacky code, no standards |
| Core Web Vitals & Speed | Guaranteed sub-1.0s LCP & 95+ Lighthouse | Rarely prioritized | Often ignored or bloated templates |
| Post-Launch Bug Warranty | 14-Day zero-cost fix guarantee | Expensive retainer required | Disappears after final payment |
| Code & IP Ownership | 100% full transfer & documented handover | Proprietary lock-ins / extra fees | Varies / often messy repos |

Open Source · Public Track Record
I don't just talk about code. I ship it — every week.
A portfolio can be polished. A commit history can't. This is my real, live GitHub activity — the same consistency your project would get.
- Public commit historyEvery line of code I ship is verifiable — no private sandbox demos.
- Consistent, not occasionalThe graph below is my real activity. I build every single week.
- Open-source firstI contribute back to the tools I use, not just consume them.
