About this gig

Are you facing slow database queries, scaling bottlenecks, or needing a secure REST API for your web or mobile app? Ive got you covered.


I am a Senior Backend Engineer with 4.5+ years of experience architecting high-throughput systems, event processing pipelines, and microservices. Having engineered streaming platforms handling 300,000+ daily events, I build production-grade backends designed for sub-second latency and rock-solid reliability.


WHAT I OFFER:

  1. Custom REST APIs & Microservices (Python, FastAPI, Flask, Go)
  2. Authentication Engines (OAuth 2.0 Identity Providers, SAML, JWT, RBAC)
  3. Database Architecture & Query Optimization (MongoDB, PostgreSQL, Redis)
  4. Async Processing & Event Streaming (Kafka, Celery, Background Workers)


WHY CHOOSE ME?

  • Sub-Second Performance: Slashed DB query execution times from 100s to <1s.
  • High-Scale Reliability: Zero-data-loss architecture built for high event throughput.
  • Enterprise Code Standards: Clean, modular, fully-documented, and test-driven code.


Lets turn your vision into a scalable product. Message me today to discuss your project!

I am a Software Engineer with over 4.5 years of hands-on experience architecting high-throughput backend systems, scaling microservices, and building enterprise-grade SaaS features. My track record at Kissflow highlights my ability to solve complex technical bottlenecks—from re-engineering audit data pipelines with Apache Kafka to handle over 300,000 daily events without data loss. Whether it’s building full OAuth 2.0 Identity Provider flows from scratch, optimizing multi-threaded background processing engines, or integrating AI feature management platforms.
