Why CTOs and Tech Leads choose Adfiro
No junior developers billed at senior rates, no administrative friction. Uncompromising engineering standards, strict deadlines, and true relief for your core team.
DACH-Ready (13 Years)
Direct technical and business communication in German (C1 Level). 13 years delivering for clients in Germany, Austria, and Switzerland. Full understanding of GDPR/DSGVO, compliance, and DACH work ethics.
Task Force Model
Two flexible deployment modes: solo Lead Architect OR a tight 3-person Senior Task Force (with 2 trusted Senior Developers). Immediate project momentum without recruiting bottlenecks.
Zero Micromanagement
Autonomous engineering at its best. Asynchronous workflow, accurate estimates, and 100% ownership of architecture and end-to-end delivery. You define the business goals – we ship robust code.
Proprietary Modules
We avoid reinventing the wheel. Access to our proprietary library of battle-tested architectural components (auth, admin, billing, n8n), cutting time-to-market by 40-60%.
How we partner with your tech team
Flexible collaboration structures aligned with your product roadmap and engineering velocity.
Autonomous System Build
Full-lifecycle engineering of custom web applications, B2B portals, or new subsystems from architectural design to cloud production rollout.
• 100% end-to-end technical delivery
• Modern stack (Symfony + Angular)
• Post-launch SLA & system maintenance
Senior Task Force (Staff Aug)
Direct reinforcement of your engineering squads. Onboard as a Senior Architect or inject a cohesive 3-person task force to rapidly execute critical features.
• Fast onboarding within days
• Zero recruitment overhead
• Seamless integration into Jira / GitHub / Slack
Legacy Refactoring & Audit
Technical debt reduction, framework version upgrades (PHP/Symfony), slow PostgreSQL/MySQL query tuning, and eliminating architectural bottlenecks.
• Safe zero-downtime migrations
• Query profiling & caching strategies
• Architectural audit & remediation plan
