// about

Builder. Problem-solver. Owner.

I'm a backend and cloud engineer based in Pune, India. At Contextine Softwares, I was the dedicated technical point of contact for a SaaS client — running weekly requirement sessions and owning the full cycle from client requirement to AWS architecture to deployment, independently.

I care about understanding why systems work, not just how to operate them. When the Lambda function wouldn't import a Pydantic module, I didn't guess — I checked the binary architecture, traced the GLIBC version, and found the CPU mismatch. That's the kind of engineer I am.

Currently building toward a universal developer skillset: deep on backend and cloud, growing fast in AI/LLM engineering, and committed to fundamentals that transfer across tools and stacks.

Forward Deployed Engineering

Client-facing, ambiguous requirements, end-to-end ownership — translate business needs into shipped systems.

Cloud Infrastructure (AWS)

Lambda, RDS, S3, SQS, VPC, IAM, CloudWatch — built and debugged production deployments, not tutorials.

AI / LLM Engineering

RAG pipelines, Gemini function-calling, tool-using agents, evaluation-aware design.

CI/CD & Infrastructure as Code

GitHub Actions pipelines with manual approval gates, Terraform blueprints, least-privilege IAM by default.

Things I've built and deployed

⚡
GitHub →
Client Data Onboarding Pipeline
Event-driven data pipeline: client drops a CSV in S3, Lambda processes it automatically, validated rows land in RDS Postgres. Generator-based ingestion for memory efficiency, selective retry logic (transient errors only), and graceful duplicate detection. Debugged through four infrastructure failures — Python version mismatch, CPU architecture conflict, VPC networking, and a missing S3 Gateway Endpoint.

Agentic Research Assistant
A tool-calling research agent powered by Gemini's function-calling API. The model — not hand-written routing logic — decides which tool to invoke based on tool docstrings: document search (RAG over uploaded PDFs via cosine similarity), web search (DuckDuckGo), or a safe AST-based calculator that avoids eval() injection risks entirely.

NL-to-SQL Assistant
Natural-language-to-SQL conversion powered by the Gemini API, with a deliberate safety layer that parses generated SQL through Python's AST module and blocks all non-SELECT statements before execution — preventing accidental or malicious data modification.

Pharma Analytics Dashboard
Interactive analytics dashboard built over synthetic pharmaceutical commercial data, using SQL window functions to surface trend and cohort-level insights — ranking, running totals, period-over-period comparisons — served through a Streamlit interface.
