Questions?

Frequently Asked Questions

Find answers to common questions about my expertise and process.

How do you work with clients across different timezones?

I work PKT (UTC+5), which gives me natural overlap with US East Coast mornings (my afternoon) and full coverage of EU business hours. I use async-first workflows — daily written updates, Loom videos for demos, and a shared project board so you always know where things stand without needing a call. For time-sensitive projects, I'm flexible on hours.

Are you open to full-time remote roles?

Both. I'm open to full-time remote positions and long-term contracts. I'm set up to work as a remote contractor through Deel, or direct contracts. If you're hiring for a senior AI/backend role and want someone fully embedded in your team, let's talk.

What technologies do you specialize in?

I specialize in building production-ready Python backend architectures and AI systems. My day-to-day stack includes FastAPI, Flask, AWS, Docker, LangChain, and OpenAI/Gemini integrations. I also build robust frontends using ReactJS when a full-stack solution is required.

Can you work with my existing team?

Absolutely! I offer flexible engagement models including full project ownership, team augmentation, and technical consulting. I can integrate with your existing workflows using tools like Jira, Slack, and GitHub. I'm comfortable working in both independent and collaborative environments.

Do you sign NDAs and confidentiality agreements?

Yes, I understand the importance of protecting your intellectual property. I'm happy to sign NDAs before discussing project details. All project code and data are kept strictly confidential and are never shared with third parties.

What if I need changes after the project is complete?

Post-launch changes are handled through our support agreement. Bug fixes are covered during the free support period. For feature additions, I provide a separate quote. I also offer monthly retainer packages for ongoing development needs.

Can you help with AI/ML integration in my existing application?

Yes! I specialize in integrating AI capabilities into existing applications. This includes adding chatbots, recommendation systems, predictive analytics, image recognition, natural language processing, and more. I can assess your current system and recommend the best AI solutions for your needs.

Comparative Evaluation of Text Similarity Metrics for Enhanced Abstractive Summarization on CNN/DailyMail Corpus

Published in: Journal of Computational Biology and Informatics (JCBI)

Investigated and analyzed various text similarity metrics to improve the quality of abstractive summarization on the CNN/DailyMail dataset. The research focused on enhancing the coherence and relevance of generated summaries through advanced similarity measurement techniques.

Abstract

This research presents a comprehensive comparative analysis of various text similarity metrics and their impact on abstractive summarization quality. Using the CNN/DailyMail corpus, we evaluated multiple similarity measures including semantic, syntactic, and hybrid approaches to determine their effectiveness in improving summary generation. Our findings demonstrate significant improvements in summary coherence and factual accuracy when incorporating optimized similarity metrics into the summarization pipeline.

Key Contributions:

  • Comprehensive evaluation of text similarity metrics for summarization
  • Novel approach to integrating similarity measures in abstractive models
  • Empirical analysis on large-scale CNN/DailyMail dataset
  • Performance improvements in summary quality and coherence
