What I'm looking for

I'm looking for a senior backend or AI engineering role where I can own high-scale distributed systems and build applied AI features end-to-end. I thrive in remote-first teams that value measurable outcomes, fast iteration, and strong engineering fundamentals.

I’m a Senior Software Engineer with 8+ years of experience building high-scale distributed systems and AI-powered products. I focus on designing backend infrastructure that performs under real-world load and evolves quickly as product needs change.

At Frameplay, I engineered backend infrastructure serving 100K QPS via OpenRTB and reduced critical request latency from 900ms to 200ms. I delivered this through a streaming/latency-optimized pipeline using Go concurrency (goroutines), plus an event-driven microservice backend with GraphQL, SQS/SNS, and Step Functions.

As Co-Founder & AI Engineer at Kak Saku, I built and shipped a multimodal AI tutoring experience in 4 months—integrating Claude for tutoring, Gemini for OCR-based question parsing, and Whisper for voice processing. I implemented RAG using Voyage AI embeddings with PostgreSQL + Redis for fast, personalized retrieval, then launched WhatsApp-native features, gamification, parent-child progress dashboards, and exam simulation.

Earlier, I strengthened my product and delivery muscle across industries—developing fullstack systems at BizCover and leading engineering as Engineering Lead / IT Manager at Clodeo (Lunapos/Lunaone), where I managed a team of 15 engineers and set up infrastructure and CI/CD. I bring that same hands-on approach—clean systems, pragmatic tooling, and measurable performance—into every role.
