→ Reduced HSM validation effort by 50%
→ Built offline-first AI log tooling
→ Integrated bot protection across mobile stacks
I’m a Software Engineer currently working at Thales on cryptographic systems, secure infrastructure, automation tooling, and AI-assisted investigation platforms.
My work spans HSM workflows, backend systems, mobile security integrations, and developer tooling focused on simplifying complex engineering problems.
Outside work, I enjoy building systems-focused projects exploring security, intelligent tooling, local LLM workflows, and infrastructure design.
Security should be embedded into architecture from the beginning, not layered on after deployment.
Sensitive data should remain within trusted environments whenever possible, especially in AI-assisted workflows.
Engineering time should be spent solving problems, not repeatedly executing predictable workflows manually.
Well-designed tooling and clear workflows reduce complexity and help teams move faster with confidence.
Thales • Noida, India
Engineered secure payment workflows on Thales payShield 10K HSM using RSA, AES/3DES, Multi-LMK, PKCS, and ISO/ANSI standards.
