WaffBell

Technical Lead / Software Engineer

I lead end-to-end delivery across real-time 3D, platform engineering, and CI/CD—from problem framing to architecture, implementation, and operational excellence.
I turn complexity into shippable value with clear decisions and clean execution.

Architecture & Decision Making

Clarify constraints and trade-offs, then commit to the right architecture and priorities.

End-to-End Technical Leadership

Lead across phases—from prototype/PoC to productization and operations—with clear decisions and execution.

Productization & Operational Quality

Build quality into the system and keep improving with CI/CD and observability.

ABOUT

Profile

Background & approach

Since 2017, I have worked across real-time 3D (Unreal Engine / C++), development platforms (CI/CD), and operational improvements in entertainment and sports domains.

From early prototyping and PoC through productization and operations, I lead requirement clarification, technical decision-making, and quality uplift for long-running systems.

WHAT I LEAD
Architecture & Decision Making

Clarify requirements, constraints, and risks; then make the design and priority calls.

  • State management and data-flow design
  • API and module boundary definition
  • Trade-offs across performance, quality, and timelines
End-to-End Technical Leadership

Led prototyping of a speech-recognition-based AI agent, using JavaScript, Android, and Linux environments to iterate rapidly through early hypothesis validation and technical feasibility checks.

  • Prototype → product transition design
  • Quality bar definition and review process
  • Alignment, risk management, and execution planning
Productization & Operational Quality

Build for “keep running”: improve operational quality and continuous improvement loops.

  • Stable operations through CI/CD and automation
  • Observability and debugging readiness
  • Standardized procedures and iterative improvement
CAREER TIMELINE

This section grows over time as new projects are added. I can support across phases—from prototypes to operational excellence.

ENGAGEMENT

Depending on the project phase, I take ownership as an architect—designing, implementing, and driving key technical decisions.

Architecture Ownership

Frame requirements and constraints, decide architecture and technology choices, and translate them into implementable plans.

Hands-on Engineering

From prototype to delivery, I contribute hands-on with quality, performance, and maintainability in mind.

Technical Leadership

I lead prioritization, alignment, reviews, and process improvements to keep delivery moving.

Deliverables
  • Architecture docs (diagrams / principles / decision log / high-level & detailed design docs)
  • Implementation PRs & reviews
  • Roadmap & prioritization draft
  • Operational improvements (automation / standardization)
