About · Manuel Sepúlveda

I’m Manuel Sepúlveda. I build backends and smart contracts where signatures, privacy and data provenance matter. I’m completing a double degree at Universidad de Chile, Computer Engineering and an M.Sc. in Computer Science, which closes with a single thesis.

My thesis, at CLCERT, designs a cryptographic mechanism to publish statistics of a verifiable electronic vote without compromising ballot secrecy. It is submitted and under review; I explain it in more detail on the Research page.

From 2024 to 2026 I worked as a software developer at DIMACOFI. I built a multi-tenant kiosk for schools from scratch, which was installed in a school, and automated the update of more than 2,000 billing-critical addresses in Oracle EBS with Python and Selenium.

In October 2026, Nodus won Best University Project (1st place, University Track) at Find Your Way Hackathon (Tellus and Stellar). Nodus nets circular debts between SMEs in a single transaction, moving only the net balance. In August 2026 I was one of three CLCERT students selected to represent Universidad de Chile at the CiberLAC Cybersecurity School.

I’m looking for work as a backend, full-stack or security engineer in Santiago, remote or hybrid, preferably on teams that work in English.

Experience

Master’s thesis researcher

CLCERT, Universidad de Chile · Santiago, Chile

Mar 2025 to present

M.Sc. in Computer Science thesis on the secure publication of aggregate statistics in verifiable electronic voting. Advisors: Alejandro Hevia and Camilo Gómez. Submitted and under review; defense expected between December 2026 and February 2027.

My master’s thesis at CLCERT, Universidad de Chile, designs a cryptographic mechanism to publish statistics of a verifiable electronic vote without compromising ballot secrecy, in the context of UParticipa.
The thesis aims for published voting statistics that are useful without breaking ballot secrecy or end-to-end verifiability.

Software Developer

DIMACOFI S.A.

Jul 2024 to Apr 2026

IT department: internal systems, products for clients and technology exploration for automation, customer service, education and cloud integration.

Built an educational kiosk from scratch, frontend and backend: a multi-tenant interactive touchscreen platform for schools, installed in a school. Stack: React, Electron, FastAPI, SQLModel, Cloud SQL, Cloud Storage, Cloud Run and Docker.
In the educational kiosk, implemented JWT authentication with roles (administrator, teacher and student), QR login for the touchscreen, document uploads for teachers and document printing for students.
Connected the educational kiosk to real printers: PaperCut to control print quotas and costs, and SNMP to monitor toner, paper and errors.
Gathered the needs of different schools with DIMACOFI’s marketing and sales teams, and met them with a multi-tenant design that separates data and configuration per school.
Automated the update of more than 2,000 billing-critical addresses in Oracle EBS; by hand, 100 records took about 3 days. The workflow stayed reusable for new records.
Designed the Python workflow behind the Oracle EBS address automation: normalization and deduplication in SQLite, batch enrichment against Oracle, reports of missing or ambiguous matches for manual review, and Selenium with logs.
During my first internship at DIMACOFI (January to March 2024), built a working demo of an AI virtual assistant for customer service over WhatsApp, with ticket creation through an internal API, product recommendations with images and email verification by PIN. Stack: Botpress, ChatGPT Assistants, Make and WhatsApp Business.
In the AI virtual assistant demo, gated critical functions behind a prior verification enforced by the flow state in Botpress, instead of relying only on instructions to the language model.
