About
I'm a B.Tech graduate in Computer Science Engineering (AI & ML), with an 8.5/10 CGPA and a strong foundation in object-oriented programming, data structures & algorithms, SQL, and backend development. I build with Python and C++, and gained hands-on backend engineering experience through two Excellent-rated internships at Maruti Suzuki. From concurrent security utilities to a deployed privacy tool, I enjoy taking products from architecture to production with clean, well-tested code and a practical systems mindset.

Why hire me?
Backend fundamentals that ship
I turn Python, Flask, SQL, and networking fundamentals into usable tools - from local-first privacy workflows to concurrent security utilities.
Evidence-driven problem solving
800+ LeetCode problems and two Excellent-rated Maruti Suzuki internships reflect disciplined debugging, algorithmic thinking, and clean implementation.
Systems awareness
I bring a security-minded understanding of DNS, TCP/IP, HTTP, TLS, and concurrency - useful when backend code meets real infrastructure.

Experience
Project Trainee — ICSMSAM (Cybersecurity)
Jul 2025 – Aug 2025
Maruti Suzuki · Gurgaon · Grade: Excellent
- Engineered a 4-stage subdomain enumeration pipeline combining multithreaded DNS brute-forcing, passive OSINT via Bing scraping, and crt.sh certificate transparency queries, with concurrent HTTPS live-host verification.
- Architected a configurable thread-pool concurrency model (ThreadPoolExecutor, default 20 threads) with an argparse-driven CLI, cutting scan time on large wordlists.
- Built and shipped a CLI hashing utility (MD5, SHA-256) with persistent hash-to-plaintext lookup storage.
Project Trainee — ITSEC (IT Security)
Jun 2024 – Jul 2024
Maruti Suzuki · Gurgaon · Grade: Excellent
- Developed a multithreaded network port scanner in Python using socket APIs, concurrently scanning custom port ranges with service identification via port-to-service resolution.
- Implemented structured audit logging (rotating file handlers, UUID session tracking) and optimized scan performance through concurrent TCP handling.
- Partnered with a cross-functional team to gather requirements and contribute to solution design.

Projects
Built for people who need safer workflows and faster security visibility. Each project turns a practical engineering problem into a deployable, maintainable tool.
CipherVault Live
↗
A password-based privacy tool that lets anyone lock and unlock messages or files without creating an account.
Impact: gives privacy-conscious users a simple, deployed, local-first way to protect sensitive content without trusting a third party with their data or passwords.
Read project story →Attack-surface mapping tool: a 4-stage pipeline combining multithreaded DNS brute-force, Bing-based OSINT scraping, and certificate transparency queries with concurrent HTTPS live-host validation.
Impact: helps security and pentest teams surface hosts that manual recon can miss, while reducing repetitive discovery work into one concurrent workflow.
Read project story →Suite of security components: a concurrent port scanner with rotating-file audit logging, a CLI MD5/SHA-256 hashing tool with persistent lookup storage, and a Tkinter signature-detection file scanner.
Impact: consolidates routine security checks for engineers, reducing tool switching while preserving traceable audit output for each scan.
