Cover Letter
A personalized introduction highlighting my passion for Software development and what I can bring to your team.
Dear Hiring Manager,
I’m a Software Engineer with a strong focus on Python development, backend architecture,
and cloud-native solutions on GCP. Over the past few years, I’ve designed and deployed
scalable systems using Flask, FastAPI, GraphQL, and SQL/NoSQL databases, while
automating CI/CD pipelines and containerized deployments for reliability and speed.
My work extends deeply into AI engineering, where I’ve built and orchestrated
intelligent agent systems with LLMs such as OpenAI, Claude, and Gemini. I’ve designed
Retrieval-Augmented Generation (RAG) pipelines with vector databases like Pinecone,
AlloyDB (pgvector), and MongoDB, improving semantic search accuracy and enabling faster,
more relevant knowledge retrieval.
In addition to my technical background, I’ve taken on leadership responsibilities as a
Product Owner, driving GenAI projects end-to-end — from understanding client
requirements to architecting and delivering production-grade AI solutions that cut down
manual effort and improved efficiency by over 50%.
I’m also passionate about research and innovation, with a published paper on optimizing
energy trade in Virtual Power Plants (Springer, ICDAM 2024). My achievements include
winning Kotak Mahindra Bank’s REIGN Hackathon and reaching the finals of Google Cloud’s
The NEXT Big Thing, experiences that strengthened my ability to innovate and lead under
high-stakes environments.
I enjoy taking on complex challenges at the intersection of software engineering and
applied AI, and I thrive on building solutions that deliver tangible impact.
I am enthusiastic about opportunities that allow me to apply my skills in Python
development, AI integration, and cloud-native architecture to create meaningful and
reliable solutions. I am confident my background and drive for innovation would enable
me to make a positive contribution.
Thank you for your time and consideration. I look forward to the opportunity to discuss
how my skills and experiences can align with the needs of your team.
Sincerely,
Hartej Singh
