What I'm looking for

I seek senior engineering roles building scalable, cloud‑native systems where I can lead architecture, mentor teams, and drive automation and measurable product impact.

I am a Senior Software Engineer with seven years of experience designing, building, and operating scalable full‑stack systems across e‑commerce, healthcare, and SaaS platforms.

I specialize in Python, Node.js, React/Next.js, Angular, and cloud‑native architectures on AWS and GCP, with deep experience in payment integrations (Stripe, PayPal) and backend microservices.

I've led backend efforts for high‑traffic platforms, improved system reliability and API performance, automated operational workflows, and implemented robust security and OAuth2 integrations to enable safe third‑party collaborations.

I champion Agile practices, mentor engineers, drive DevOps and CI/CD adoption, and focus on delivering measurable business impact through automation, observability, and practical AI/automation initiatives.
