Senior Backend & Cloud Profile
Designing resilient, scalable systems with relentless focus on latency reduction, high concurrency, and extreme cost optimization.
Senior Backend Engineer specialized in Golang with 7+ years of experience designing high-performance APIs, distributed systems, and cloud-native architectures. Proven results in latency reduction, high-load concurrency handling, and cost optimization across S&P 500 companies (Microsoft, The Home Depot via TCS). Strong background in cloud engineering (Google Cloud Platform, AWS, Azure) and DevOps automation.
High-Concurrency & Latency
Leveraging Go routines, channels, and zero-allocation pipelines to handle intense traffic with microsecond response times.
GCP & Cloud-Native Scale
Production serverless deployments on Google Cloud Run, Firebase Auth, automated CI/CD pipelines, and zero-downtime releases.
Extreme Cost Optimization
Cutting production infrastructure overhead by up to 30% through memory profiling, right-sizing, and clean multi-regional routing.
Zero-Lock-in Philosophy
Architecting decoupled codebases and open-source foundations where clients retain 100% ownership of their data and infrastructure.
Wacucoco.com
High-concurrency gamified promotional platform engineered with Go Clean Architecture, Redis, and Google Cloud Run.
Wacucoco
wacucoco.comWacucoco is a gamified promotional platform that delivers randomized discount offers to users while granting merchants precise control over their discount distribution inventory (e.g., configuring limits for 10%, 15%, or 25% tiers). The system features a bespoke, N-tier payment gateway proxy that enables each merchant to securely process transactions using their own independently encrypted gateway credentials.
Core Architecture & System Highlights
Engineered for high concurrency, zero-leak credential isolation, and sub-millisecond inventory decisions:
Go Clean Architecture
Strict separation of Domain Entities, Use Cases, Interfaces, and Delivery Layers. Completely framework-agnostic core ensuring high testability, zero bloat, and fast execution.
Bespoke N-Tier Payment Proxy
Custom proxy layer enabling every merchant to securely process checkout transactions using their own independently encrypted gateway credentials with zero cross-tenant leakage.
Google Cloud Run & GCP Stack
Serverless containerized backend auto-scaling instantly during traffic surges. Integrated with Firebase Auth for identity management and Google Engine Run.
Discount Inventory Engine
High-speed quota validation backed by Redis. Merchants define precise distribution limits (10%, 15%, 25% tiers) guaranteed without concurrency race conditions.
User engages with gamified promotion; authenticated via Firebase Auth.
Clean Architecture handles business logic and anti-fraud validation.
Atomic evaluation and quota decrement for 10%, 15%, 25% tiers.
Checkout processed using merchant's independently encrypted gateway.
Technical Skills & Stack
Engineered for high concurrency, low latency, and production-tested at Fortune 500 scale.
