Available to hire
I’m Ashwinikumar Vishwakarma, a Full Stack Software Engineer with 6+ years of hands-on experience building enterprise-grade CRM systems, automated case management workflows, and financial infrastructure for asset managers, brokers, and banks. I specialize in secure, scalable, real-time solutions using C#, Go, ReactJS, and CI/CD pipelines, and I enjoy collaborating with front office, middle office, and back-office teams to deliver risk management, compliance automation, margin calls, and FIX-based trade capture solutions.
I have a track record of integrating critical third-party APIs and leveraging Apache Airflow for job scheduling in data-sensitive environments. My recent work includes migrating legacy margin logic to CME SPAN2, implementing FIX drop-copy feeds from multiple exchanges, and automating reconciliation and document workflows. I am passionate about API-first architectures and mentoring teams toward resilient software delivery.
