Executive profile
End-to-end technical ownership.
Lead Backend Engineer and Technical Architect with more than 20 years of experience architecting, modernising and operating production-grade platforms.
Owns the full technology lifecycle—from architectural decisions and implementation to Infrastructure as Code, CI/CD, observability, security, cost governance and production operations. Combines deep backend and distributed-systems experience with current hands-on delivery of serverless, multi-platform products.
Technical highlights
Impact before implementation detail.
- 01
Architected cloud-native platforms from concept through production.
- 02
Designed scalable serverless architectures around resilience and predictable operating costs.
- 03
Established Infrastructure as Code and repeatable cloud delivery with Terraform.
- 04
Introduced cloud governance, observability and operational guardrails before scale demanded them.
- 05
Designed architecture-guided, multi-agent software engineering workflows with human technical ownership.

DjobiLi
Co-founder & Lead Software Architect
A community marketplace conceived as a complete production platform—not simply an application.
02
Architecture
Established clear boundaries between the client experience, serverless business workflows and operational services, allowing each concern to evolve without compromising the whole platform.
03
Platform Engineering
Established Infrastructure as Code, automated deployments and cloud governance so environments remain repeatable, controlled and observable from development through production.
04
Backend & Search Engineering
Architected a denormalised Firestore data model and synonym-based search engine that minimised Firestore reads, improved search performance and optimised cloud operating costs.
Designed idempotent functions, atomic operations and strict data-access controls for resilient serverless workflows.
05
AI Engineering
Designed architecture-guided workflows using Claude Code, Gemini and OpenAI Codex to accelerate implementation, architectural review, controlled code generation, testing and documentation.
Structured reusable instructions, context and multi-agent validation to improve consistency and reduce model drift.
06
Operational Excellence
Introduced observability, reliability controls, proactive usage monitoring and cost governance to make performance and cloud expenditure visible before production scale.
Senior Engineering Lead & Technical Architect
- Led AWS architecture and production operations, with approximately 80% of delivery focused on DevOps and platform reliability.
- Automated modular infrastructure with Terraform and Docker, reducing provisioning time by approximately 40%.
- Built delivery pipelines that shortened release cycles by 35% and established observability that contributed to 25% fewer production incidents.
- Modernised legacy PHP monoliths into independently deployable Symfony and Node.js services.
