About
Hi, I'm Sahil. My engineering roots trace back to Government Polytechnic, where I studied Information Technology, an unforgettable chapter filled with great friends, late-night labs, and foundational tech skills. I leveled up that curiosity with a B.Tech in Artificial Intelligence from GHRC, setting my focus squarely on modern intelligent systems and creative problem-solving.
I also bring a year of hands-on experience as an Operations Manager. In that role, I was the bridge between teams: managing cross-functional communication, enforcing critical deadlines, optimizing processes, and collaborating directly with clients. It gave me the operational discipline to ensure that what gets built actually gets delivered effectively.
When it comes to building, I am a software engineer. I write code to solve real-world problems leveraging Generative AI as a powerful tool in the stack rather than relying on it as a substitute for true programming fundamentals. Technology is moving at a breakneck speed, and that constant evolution is what drives me. I am a perpetual learner who loves reading about the latest technological advancements and turning fresh concepts into dependable software.
Experience & Roles
Operations Manager
Directed end-to-end client communication, translating business requirements into actionable project plans and consistently meeting delivery expectations.
- Coordinated cross-functional engineering teams and streamlined client onboarding, keeping concurrent projects aligned, on schedule, and issue-free.
- Tracked and delivered on deadlines across concurrent projects, maintaining full visibility and accountability from kickoff to delivery.
Web Development Intern
Designed and deployed 5+ end-to-end client websites using WordPress, including custom theme development and production troubleshooting.
- Engineered custom responsive themes tailored to unique business branding and performance targets.
- Translated client requirements into technical implementation, delivering solutions aligned with business objectives.
Featured Projects
MakeMeShort — Full-Stack URL Shortener
Architected and deployed a full-stack URL shortener featuring JWT authentication, custom vanity slugs, real-time click analytics, and dynamic QR code generation.
- Engineered REST APIs for link management and applied security best practices: bcrypt password hashing, rate limiting, Helmet HTTP headers, and SSRF protection to safeguard internal network metadata.
- Automated testing with Node's built-in test runner and Supertest; containerized the application with Docker and deployed it continuously on Render.
Skin Disease Detection & Classification
Built and deployed an automated clinical diagnostic assistance image classification system via an interactive Streamlit web application.
- Applied transfer learning on pre-trained EfficientNet architectures with custom classification heads for dermatological condition screening.
- Improved model generalization through extensive data augmentation (rotation, zoom, flips) and learning rate fine-tuning.
Spam Mail Detection System
Developed an end-to-end Machine Learning and Natural Language Processing (NLP) email classification system deployed as an interactive web application on Streamlit Community Cloud.
- Engineered custom text preprocessing (canonical tokenization for URLs, emails, currencies, and numbers) with sublinear TF-IDF vectorization (unigrams & bigrams, 10k vocabulary).
- Trained and serialized a lightweight Multinomial Naive Bayes pipeline achieving 95.10% test accuracy, 96.92% spam recall, and 92.03% F1-score on the Enron email dataset.
- Built an interactive Streamlit dashboard featuring instant classification, confidence probability distribution, and transparent held-out diagnostic metrics.
Pixellkey Enterprise Client Platforms
Designed, built, and launched multiple commercial WordPress websites tailored to specific client business models and branding guidelines.
