What I'm looking for

I’m looking for a role where I can build and troubleshoot web integrations, deliver reliable API-driven platforms, and use strong technical support and problem-solving to drive quality results and long-term growth.

I’m a motivated Junior Web Developer with experience in technical support and computer hardware troubleshooting, bringing a strong problem-solving mindset to every project. I’m skilled in both front-end and back-end development and aim to deliver high-quality results within deadlines.

In my current role as an SMS Platform Integration Specialist, I designed and maintained an organization website to capture partner onboarding data, integrating Google Sheets to automate lead collection and streamline follow-ups. I also conduct end-to-end API parameter testing for SMS gateway integrations using Postman, then coordinate with gateway providers to identify and resolve performance issues, improving reliability and reducing recurring errors by 30% through better integration documentation.

Previously, as Head of Operations, I led operational workflows, improved productivity and efficiency, and drove measurable customer outcomes—cutting project completion time by 15% and increasing customer retention by 25% through stronger after-sales support. Earlier, as a Technical Engineer/Database Administrator, I reduced system downtime by 30% with streamlined POS repair processes, improved system uptime by 20%, and supported SQL-based reporting and Microsoft Server/LAN/Wi‑Fi administration.
