Xavier Lim Lead Engineer at MFI Ventures

Engineering, from idea to production.

I help clients choose the right solutions, build the systems behind them, and lead teams from discovery to dependable software.

Solutions engineering. Product delivery. Team leadership.

Hands-on engineering.
Ownership beyond the code.

Solutions engineering & presales

Helping clients choose.
Helping partners deliver.

At VST-ECS, I connected business requirements with solution design, hands-on validation and partner enablement.

That included RFP/RFI responses, mapping Terms of Reference (TOR) to technical requirements, and validating the fit through proofs of concept, feasibility reviews and acceptance criteria.

CDAO Philippines

Making enterprise AI understandable.

Demonstrated Informatica IDMC and CLAIRE GPT / CLAIRE AI, showing how data quality, lineage and access controls support enterprise AI. Turned attendee questions into practical architecture discussions.

Partner workshops · Cebu & Davao

Helping partners put the platform to work.

Delivered an actionable introduction to Informatica IDMC: where it fits, how to use it, and how to turn architecture discussions into deployable, cost-effective patterns and clear next steps.

Retrieve what matters. Review against the same evidence.

Led the rollout, built the custom harness, and coached the team.

A shared workflow for AI-assisted engineering

Turned separate coding tools into a shared development and review practice, teaching engineers to direct agents and check their work.

Any engineer can verify the fix independently.

Led the migration strategy, implementation, and team adoption.

Modernizing legacy systems for faster delivery

Led the move away from slow ERP cores and patched-together services, making features easier to change and bugs easier for engineers to reproduce.

Technical leadership

Leading teams.
Keeping clients involved.

I lead projects from the first client conversation through delivery. I stay involved in architecture, code, and reviews—and teach the team the practices that make the next project easier to deliver.

Engineering leadership

I lead architecture decisions and work in the code alongside the team. I match ownership to engineers’ strengths and teach practical ways to develop, debug, and review—not just assign tasks.

Client collaboration

I turn client goals into a practical plan, explain options and trade-offs, and use demos and progress updates to keep decisions clear.

Partner team support

I run technical workshops and create step-by-step guides so partner engineers and consultants can understand, demonstrate, and deliver the work.

Built on hands-on experience.

Solutions engineering and presales, product leadership, and hands-on delivery.

Infrastructure that supports the whole delivery path.

AWS work includes S3, EC2, RDS/Aurora, and Lambda. My current infrastructure work also covers cloud and bare-metal production server administration, deployment checks, backups, and recovery. Platform experience spans separate projects; these are not a single architecture.
