## 2. Commercial Role, Priority Construction Sectors & Strict Operating Boundaries
SerSourcing operates as a transparent, fee-based buyer-side sourcing, factory verification, technical quotation comparison and shipment-readiness office in Türkiye for international importers, distributors, contractors, modular developers and project buyers.

Top-Priority Construction & Industrial Focus (#1–#9): (1) Light-gauge steel houses & steel villas (LGSF, EN 10346 S350GD+Z275), (2) Prefabricated modular homes & flat-pack site cabins, (3) Pre-engineered steel warehouses, factory buildings & hangars (EN 1090-2 EXC2/EXC3), (4) Structural steel profiles & cold-formed Z/C/Sigma purlins, (5) PIR/PUR & mineral-wool roof/facade sandwich panels (EN 14509), (6) Fibercement (Betopan), gypsum & exterior sheathing boards, (7) Stone-wool, XPS/EPS & waterproofing membranes, (8) Villa pivot doors, hangar industrial doors & thermal-break windows, and (9) Aluminum curtain-wall & facade systems — alongside marble/travertine, porcelain ceramics, sanitaryware, custom hospitality millwork, HVAC/plumbing/LED building equipment and turnkey villa/hotel packages across 21 sectors (strictly excluding electrical cables and switchgear).

- Buyer Representation Principle: Goods sales contracts and goods payments remain directly between the buyer and the manufacturer. SerSourcing takes zero undisclosed factory commissions. If CFY ever offers direct material supply on a separate commercial track, it is explicitly quoted in writing as a seller offer.
- Strict Technical & Legal Boundaries: SerSourcing is NOT an EU/UK Notified Body, accredited testing laboratory, statutory structural engineer of record, CE/UKCA/DoP signatory, customs broker, importer of record, freight carrier or marine insurer, and does NOT claim resident staff in every Turkish city (field attendance is dispatched per confirmed assignment from Maltepe, İstanbul).

### Multidisciplinary Founding Leadership
- **İdris YAĞMAHAN** (Architect · Co-Founder): Primary buyer contact leading architectural specification reviews, drawing interfaces, supplier shortlisting and scoped factory visit reporting.
- **Celalettin YAĞMAHAN** (Civil Engineer · Co-Founder): Supports structural steel profile, cold-formed framing, tolerance and industrial construction-component questions across purchasing briefs and technical reviews.
- **M. Furkan YAĞMAHAN** (Interior Architect · Co-Founder): Focuses on interior boards, acoustic & surface finishes, architectural fittings, sample alignment, export packaging details and multi-supplier order coordination.
