Pablo Thomas Landeros Mena

Software Engineer — I build complete systems: architecture, interface, logic and data, with AI integrated where it pays off. The sphere is my real stack: drag it, spin it and hover the nodes to see what holds it up.

Interchange · fast track

Short on time?

The essentials, each one with a direct exit to the proof behind it. The full route through the network is still below, untouched.

Solar System AR

The planets in augmented reality, controlled with hand gestures, for a local school

Hybrid Point of Sale

Sales, products and users for restaurants and retail stores

Role: Design, development and deployment — the whole project · Status: Open demo

Problem

Restaurants and retail stores need to record sales, manage products and administer users without fighting the system: speed at the counter and simplicity in administration.

There are more systems in production that I cannot publish: some under contract, others in private repositories. I show them on request.

Lab

Don't take my word for it: try it. Drag pieces from the toolbar, feel them snap to the alignment guides, select several with a marquee; add a chart and regenerate it with new data, optimise the space automatically and export the result at high resolution — the mechanics of a real graphics editor (the same as a diagramming tool, a floor plan or a data board), running in your browser.

Drag or click

With focus on the canvas: Enter selects the next piece, the arrow keys move the selection (with Shift, ten pixels per step), Control D duplicates, Delete removes and Escape clears the selection.

Pieces on the canvas

There are no pieces on the canvas.

How I work underneath

What holds up the systems above: working method, architecture and API design, and AI applied to real operations.

Key achievements

  1. AI integration for public tendersCompass Security · Jun. 2026

    • Designed and deployed Claude agents for public tender analysis: time to fully understand a tender document dropped from 10 days to minutes (over 95% reduction).
    • The reading and comprehension phase went from 50% to 30% of the process, freeing up 40% more time to build the commercial proposal.
    • Automated detection of logical and semantic inconsistencies in tender documents — unfeasible to catch manually within the deadlines — plus an estimate of the likelihood of amendments: zero documentation errors across submissions.
    • Historical award-data analysis revealed that winning bidders priced at roughly 90% of the available budget. Realigning bid strategy to that range moved the company from 9th–10th place to 3rd–4th in award rankings.

  2. Critical infrastructure migrationCompass Security · May 2025

    • Migrated complex enterprise infrastructure in record time, with zero service downtime.

About me

I am a Software Engineer with 9+ years of experience in full-stack development, IT infrastructure, technical leadership and software project management under agile methodologies. I founded Nagotar Technologies to turn operational needs into complete solutions, from the specification and the architecture through to deployment.

I currently lead the IT department at Compass Security nationwide, coordinating technology operations across Temuco, Santiago and Calama. There I build internal applications and integrate AI agents into real business processes.

My career started in support, networks, servers and electronic security. That grounding lets me understand both the code and the infrastructure it has to run on: the projects above are deployed and can be tried live.

Method
Spec-Driven Development: the functional and technical specification is written before the code and acts as the development contract, which cuts rework and ambiguous iterations. Requirements gathering with the client, defined scope, short iterations with validated deliveries and production rollout.
Certification
Certified AI specialist with Claude (Anthropic): Fundamentals, Developer/API, Claude Code and Skills & MCP, 2025.
Education
  • B.Eng. in Computer Science (in progress) — Instituto Profesional IACC Online, 2024 – present.
  • Associate Degree in Computer Science — Universidad Arturo Prat, 2015 – 2018.
  • Specialization courses in cybersecurity, development and AI — Udemy, ongoing.

How I work

  1. Specification before code

    First I understand the operation and write the functional and technical specification; that document is the contract that prevents rework.

  2. Software in production, not mock-ups

    The systems I deliver stay running with real users — like the ones in the stations above.

  3. Continuous support

    Support and improvement after launch: the relationship does not end when the system goes live.

Let's talk

If you need someone to carry a system end to end — the architecture, the interface, the logic and the data — this is the direct channel.
