I build software that solves real operational problems.
I’m Melquizedek Felix, a Philippines-based Ruby on Rails developer and systems engineer. I build business applications, connect existing platforms, and strengthen the systems they depend on.
I take a data-driven approach: I study how people work and what the evidence shows before deciding what to build or improve.

What I do
Software built around the work
I work where software engineering, business operations, and IT infrastructure meet.
Workflow automation & integration
Purpose-built automation for repetitive work and systems that lack the integrations a business needs.

Selected work
Real systems, measurable outcomes
Projects developed through my professional work, primarily for internal business operations.
01
Accounts Payable Automation
From repetitive invoice processing to a more reliable workflow.
I built automation that collects supplier invoice information, downloads supporting documents, and coordinates work across vendor and accounting platforms, with human review where needed.
Reported outcome: about two hours of daily processing reduced to around ten minutes.

ERP Inventory Automation
Making legacy software work with modern operational needs.
I developed browser-based automation for stock adjustments and lot allocation in an ERP without a usable API, with safeguards for incomplete or invalid changes.
Reported impact: more than 40 hours of manual updating per week before automation; about 40% of that time remains for analysis and ERP wait.

Timekeeping & IT Asset Management
Connecting attendance, people, equipment, and workplaces.
I built internal applications for attendance and asset tracking, including workstation assignments and asset lifecycles, around existing organizational workflows.
Reported impact: approximately $43,200 in annual timekeeping subscription costs avoided.

Understand the problem before choosing the technology
I start with the people, the process, and the constraints of the existing environment.
01
Business value
Solve a meaningful problem before adding technical complexity.
02
Purposeful simplicity
Choose solutions that teams can maintain and improve.
03
Reliability
Plan for failures, edge cases, testing, security, and recovery.
04
People first
Build systems people can understand, trust, and use effectively.
Technical expertise
A practical stack for real operations
My main specialization is Ruby on Rails and PostgreSQL, supported by frontend, automation, and infrastructure experience.

About me
Engineering shaped by operational experience
My background in IT operations and infrastructure has shown me how inefficient workflows, disconnected applications, and limited visibility affect everyday decisions.
I enjoy learning unfamiliar domains and building tools that keep delivering value after launch. I currently work as an IT / Ruby on Rails Developer at Basketcase Technologies Inc.
Based in the Philippines · Available for remote collaboration

Stop hand-encoding inventory adjustments — so analysts judge stock, not lots
Point-of-sale sales did not update ERP stock, so branches spent more than 40 hours a week on manual counts. Custom automation cut that grind; about 40% of time now goes to analysis and a slow platform.

End the manual invoice loop — so teams review outcomes, not keystrokes
Operations, accounting, and encoding spent about two hours each morning moving supplier invoices into the books. The same work now runs in about ten minutes so they focus on analysis and encoding.

One seat plan — single source of truth on a chaotic floor
Startups multiply seat-plan copies until nobody trusts the floor. With workstations and assets already in inventory, I put one live map in front of ops and management.
