Hi, my name is

Anay Vyawahare.

I build things for the backend.

I'm a backend engineer focused on building production-grade systems, APIs, and cloud infrastructure. Currently working at The Lead Market, where I build automation pipelines and distributed systems in Python and AWS.

01. About Me

I'm a Computer Science graduate who enjoys building reliable backend systems and understanding how things work at scale. My interest lies at the intersection of backend engineering and cloud infrastructure — writing code that is efficient, observable, and maintainable.

Over the past year I've been building production systems at a startup — from automated data pipelines and database migrations to distributed email infrastructure on AWS. I like owning problems end-to-end and thinking through architecture before writing a single line of code.

Outside of work, I'm deepening my knowledge of system design, cloud infrastructure, and distributed systems — working toward becoming a well-rounded backend and cloud engineer.

02. Experience

Software Engineer @ The Lead Market

Jan 2025 – Present

  • Architected an end-to-end automated lead generation pipeline processing 10k+ ZIP-based business queries using REST APIs, LinkedIn scraping, Google Maps integrations, and LLM-based structured extraction — generating 1,500–2,000 net-new prospects daily.
  • Led migration of 6M+ production records from DynamoDB to PostgreSQL, redesigning the relational schema from scratch, building migration scripts, and executing data cleaning.
  • Independently designed and built a distributed email warmup infrastructure using AWS Lambda, DynamoDB, and EventBridge — managing 200–250 mailboxes daily and reducing spam folder placement by 20–30%.

03. Projects

API Rate Limiter

Production-ready rate limiting library implementing four algorithms — Fixed Window, Sliding Window, Token Bucket, and Leaky Bucket — using atomic Lua scripts on Valkey. Supports up to 10,000 concurrent requests without race conditions.

  • Python
  • FastAPI
  • Valkey
  • Docker

Weather Aggregator API

REST API that aggregates weather data from an external provider, returning clean structured responses. Implements Redis caching with TTL — reducing external API calls by 80% for repeated city queries. Fully Dockerized with graceful error handling.

  • Python
  • FastAPI
  • Redis
  • Docker
