What I'm looking for

I’m looking for a team where I can build scalable, high-throughput APIs and distributed systems, integrate AI responsibly, and modernize security and frontends. I want to mentor engineers, own architecture, and ship measurable improvements.

I’m a Senior Software Engineer with 13+ years of experience designing and scaling applications across e-commerce, fintech, logistics, and edtech. I specialize in building high-throughput APIs and distributed systems, and I’ve supported 10M+ monthly transactions and 50K+ concurrent users.

At Amanikable Works, I led and mentored a team of 3 junior engineers while reporting directly to the CTO. I engineered a document automation platform with Laravel and Python, integrating LLMs (OpenAI GPT APIs) to boost paralegal review efficiency by 40%, and I improved security and trust by 30% through a scalable authentication system. I also delivered Nuxt.js/Vue.js frontends with TypeScript and Pinia, increasing enterprise adoption from 65% to 88% with measurable UI satisfaction.

Previously at ShipMonk, I architected and scaled high-throughput REST APIs with Laravel 9, processing 10M+ monthly e-commerce transactions via Shopify, Amazon, and Walmart. I migrated from monolithic systems to event-driven microservices using Apache Kafka, improving horizontal scalability by 45%, and I built real-time operational dashboards with WebSockets to reduce warehouse dispatch latency by 25%. I also established testing practices that achieved 95% coverage and reduced production frontend bugs by 35%.

I’ve continued delivering impact through AI-powered workflows, billing automation, and real-time experiences at Caribu and LRP Media—optimizing performance with database and caching improvements (e.g., cutting query latency by 40%) and strengthening reliability via CI/CD and disciplined engineering practices. I bring a practical, results-driven mindset and a strong commitment to mentoring and engineering quality.
