Traditional agencies pad bills with account managers, overhead, and junior developer markups. Here is how working directly with a principal engineer compares.
| Comparison Criteria | Shashi Kumar (Direct Senior Engineer) | Traditional Web Agency |
|---|---|---|
| Communication | Direct WhatsApp & voice calls with the engineer writing your code | Non-technical account managers; requirements diluted in transit |
| Engineering Talent | 100% architected and written by a senior engineer with 8+ years experience | Pitched by senior directors, then outsourced to junior interns |
| PageSpeed & Performance | High-performance 90+ Google Core Web Vitals score baked in | Bloated page builders and heavy plugins scoring 30–50 PageSpeed |
| Turnaround Speed | Rapid 1–2 week delivery without corporate red tape or endless meetings | 6–12 weeks of internal approvals, scope disputes, and delays |
| Pricing & Value | Transparent fixed milestones; 100% of your budget goes into code | 3x–5x inflated markups to pay for sales commissions and fancy offices |
| Code Ownership | 100% complete IP ownership, clean Git repos, and full credentials handover | Proprietary vendor lock-in and monthly hosting ransom fees |
