The browser extension helps users identify articles from publishers whose editorial and peer-review practices have attracted scrutiny—including MDPI and Frontiers—and choose how matching articles should appear, including context, badges, highlights, dimming or hiding. It also uses Crossref/Retraction Watch data to check for formal notices such as retractions, corrections, expressions of concern, withdrawals, duplicate-publication findings and reinstatements. I define product requirements and evidence hierarchies, test cross-browser and Zotero behavior, inspect API and implementation logic, reproduce failures, guide AI-assisted changes, and manage documentation, release verification and deployment. The Zotero plugin currently focuses on precise MDPI item and reference detection, including structured PubMed Central evidence and exact citation highlighting. Publisher-level context is controlled by the user and does not treat every journal or article as equivalent. Existing store identities and compatibility-sensitive identifiers are retained so the same product lineage can continue receiving updates. Current source repositories: https://github.com/notandia/browser-extension and https://github.com/notandia/zotero-plugin. ### English Wikipedia Link Converter | Telegram Bot **Creator & Project Lead** | GitHub: https://github.com/jnton/english-wikipedia-link-converter-telegram-bot | Bot: https://t.me/ToEnWikipediaBot Specified the behavior and deployment requirements for a Telegram bot running on AWS Lambda and API Gateway.

Implementation was produced through AI-assisted workflows and personally tested and iterated. --- ## Education & Certifications - **Information Technology — Open UAS Path Studies (120 ECTS)** (Aug 2026 — Present) — Metropolia University of Applied Sciences · Bachelor's-level ICT path studies · After completing 120 ECTS, eligible to apply to the BEng IT programme (admission not yet granted) · Curriculum: software development, SQL and relational databases, Unix/Linux, data structures and algorithms, CCNA networking, cloud computing, cybersecurity, ethical hacking, engineering mathematics and applied AI · Programme: https://www.metropolia.fi/en/study-at-metropolia/open-university/path-studies/it-online - **EF SET English Certificate 68/100 (C1 overall)** (Mar 2024) — EF Standard English Test · Credential: https://cert.efset.org/en/eJz39v - **Career Essentials in Generative AI** (Mar 2024) — Microsoft and LinkedIn · Credential: https://www.linkedin.com/learning/certificates/c4f1f59578e3ac2567787e262e3b2ec55debf96bbbced4d34d5edaa821d9e6d9 - **GALENOS Crowd Evidence Synthesis Training** (May 2026) — Cochrane Crowd & GALENOS · Systematic-review screening training ## Contact & Identifiers - [Email](mailto:me@mariomarcolongo.com): Direct email contact - [Website](https://mariomarcolongo.com): Main portfolio homepage - [ORCID](https://orcid.org/0000-0003-2846-7115): ORCID scientific researcher profile - [LinkedIn](https://www.linkedin.com/in/mario-marcolongo): Professional LinkedIn profile - [GitHub](https://github.com/jnton): GitHub profile and open-source repositories - [Agent-Readiness Audit](https://isitagentready.com/mariomarcolongo.com?checks=robotsTxt%2Csitemap%2ClinkHeaders%2CdnsAid%2CmarkdownNegotiation%2CrobotsTxtAiRules%2CcontentSignals%2CwebBotAuth%2CapiCatalog%2CoauthDiscovery%2CoauthProtectedResource%2CauthMd%2CmcpServerCard%2Ca2aAgentCard%2CagentSkills%2CwebMcp%2Cx402%2Cmpp%2Cucp%2Cacp): Agent-discovery and machine-readable endpoints implemented; live audit to be rerun after deployment. - [A2A Agent Card](https://mariomarcolongo.com/.well-known/agent-card.json): Agent-to-Agent discovery card - [Genomic Pipeline Codebase](https://github.com/jnton/git-nome): Personal genomics workflow and open-data pipeline - [Portfolio SSOT Codebase](https://github.com/jnton/mariomarcolongo): Source code and Single Source of Truth for this portfolio
