Bastián Ibáñez / Santiago, Chile
I design and ship full-stack systems, operational automation, and applied AI. I work from architecture and domain boundaries through delivery, observability, and recovery flows.
Based in Santiago, I build primarily with Python, Go, and TypeScript. My recent work connects agents, ERP systems, operations products, and optimization models with explicit controls for safe operation.
Core technologies
A multi-specialist agent that turns internal requests into controlled queries and operations across an ERP and analytical sources.
Operated in production · human review for sensitive actions · buffering, outbox delivery, idempotency, and targeted recovery.
Read case →A full-stack product for inventory, purchasing, quality, manufacturing, sales, waste, and reporting, built around transactional traceability.
Delivered and deployed · 255 unit tests across 57 files, verified on August 7, 2026 · E2E coverage for the main operational flows.
Read case →A planner that assigns groups to hotels and dates under capacity, availability, and transport constraints, and explains what it could not place.
Heuristic scheduling with repair + optional ILP refinement · Excel/JSON input and output · explainable partial results when constraints conflict.
Read case →A terminal coding agent written in Go, with interchangeable model providers and explicit controls around tool execution.
Four model adapters · streaming and cancellation · confirmation policy for sensitive actions · Go test suite verified on August 7, 2026.
Read case →Retries must not duplicate operations or lose replies.
Autonomy does not replace authorization when an action changes the business.
Inventory and manufacturing need traceability and protection from race-driven negative stock.
Over-constrained input should produce useful guidance rather than an opaque failure.
Providers, tools, and storage can change without contaminating the core.
Delivery includes tests and verification, not implementation alone.
I am a software engineer focused on full-stack systems, operational automation, and applied AI. I am drawn to work where a model or algorithm must coexist with real state, permissions, partial failure, and people who need to understand what happened.
I currently work on automation for e-commerce operations while studying Computer Science and Engineering at Universidad Andrés Bello. I speak Spanish and hold C1 certifications in English and German.
Two public libraries that unify local configuration and Google Cloud Secret Manager through declarative YAML, type coercion, validation, environments, and secret masking.
An anonymized freelance delivery: architecture and implementation of a responsive corporate website with data-driven SEO routes and an abuse-resistant contact flow. No client identity or link is published in this portfolio.
