Hi, I'm
Omar.
Software Developer
Software Development Engineering student, passionate about web development, mobile, and infrastructure.
I build with React, Next.js, and Astro on the web, Kotlin and React Native on mobile, and have hands-on experience in server administration, email security, and CI/CD deployments.
Looking for someone eager to learn fast and contribute to your team? Let's talk.
About.
Software engineer in training, with hands-on experience in web and mobile development, as well as server administration, email security, and application deployment. As an IT Trainee at Latin Link Blockchain, I managed VPS and cPanel servers, handled domains and SSL/TLS certificates, and coordinated continuous deployments (CI/CD) on Vercel.
I oversaw GitHub workflows, integrated and monitored Web3 services and APIs such as OpenOcean, Reown, CoinMarketCap, Zerion, and Upstash, and optimized node operation on the Songbird and Flare blockchain networks. I also analyzed web traffic and conversion KPIs with Google Analytics 4 and PostHog.
My stack includes React, Next.js, Astro, Kotlin, and React Native, backed by certifications in Python, AWS, Java, and Red Hat. I'm currently pursuing a degree in Software Development Engineering at Universidad Tecmilenio, where I chair the student IDS group.

Experience.
Led, under a project-based contract, a development team tasked with implementing a new payments feature within the company's blockchain infrastructure, adapting it to the existing systems. I was responsible for researching and reading technical documentation for API integration, planning the team's work, and ensuring the project was delivered on time and to spec. Once the defined scope was completed, the contractual relationship with the company concluded.
Orchestrated the administration of VPS and cPanel servers, including comprehensive backup management and domain administration (DonDominio, DonWeb). Implemented email security protocols (SPF, DKIM, DMARC), monitored IP reputation (RBLs), and managed SSL/TLS certificates. Oversaw GitHub workflows (Pull Requests, merges) and coordinated continuous deployments (CI/CD) on Vercel. Integrated and monitored the consumption of Web3 services and APIs such as OpenOcean, Reown, CoinMarketCap, Zerion, and Upstash. Analyzed web traffic, built custom filters, and tracked conversion KPIs using Google Analytics 4 (GA4) and PostHog. Monitored and optimized node operation on the Songbird and Flare blockchain networks. Produced detailed technical reports and resolved critical system and service incidents.
Developed cut lists and produced 3D model renderings for client presentations.
