Building bounded concurrecy APIs using Go + Shipping an MCP server and LLM service that powers a natural language interface that enables enterprise admins to execute bulk user operations across 150,000+ users.

Python, Go, MCP, LLMs, Function Calling

4th employee. Engineered Go and Python microservices with REST/gRPC APIs and an AWS Lambda + SNS notification pipeline processing 10k+ daily events at 99.9% uptime for HIPAA-compliant applications.

Go, Python, gRPC, PostgreSQL, AWS Lambda, SNS

Delivered a multi-threaded C++ barcode pipeline and Elasticsearch search layer that cut query latency by 90% across 1M+ records and boosted scan throughput 300% to 1000+ scans/min.

C++, Elasticsearch, Docker, Jenkins

Built a full-stack, software-defined fab control system with a visual node-based process designer and a concurrent Rust backend (Axum, Tokio). Engineers design fabrication workflows as directed graphs, compiled via topological sort and dispatched over WebSockets with real-time telemetry streaming. Each step type (spin coat, bake, expose) has a physically-modeled execution curve.

Rust, Axum, Tokio, React, WebSockets

Multi Agent financial pipeline in LangGraph with 4 specialist agents spanning invoice ingestion, validation, approval, and payment, with deterministic fraud, policy gates and HITL

Python, LangGraph, LLMs, Tool Calling, RAG

Implemented Raft consensus in Go with leader election and replicated logs for a fault-tolerant key-value store across a 5-node cluster, validating strong consistency across 1M+ entries under simulated network partitions. Integrated RocksDB-backed LSM-tree storage and benchmarked 10K writes/sec.

Go, Raft, RocksDB, Prometheus

Built a distributed real-time analytics pipeline using Apache Kafka and Apache Flink, processing 100K+ events/min, and a live WebSocket-powered dashboard.

Apache Kafka, Apache Flink, WebSockets

File search engine implemented three ways using AVL Trees, Linked Lists, and HashMaps. Scans documents, ranks results by keyword hit count, and supports full sentence queries — built to compare algorithmic tradeoffs across data structures.

C++, AVL Trees, HashMaps

Interactive C++ app built with SFML that animates five classic sorting algorithms in real time — Insertion, Bubble, Selection, Merge, and QuickSort (both recursive and iterative). Generate random arrays and watch each algorithm step by step.

C++, SFML

Full replica of the classic KONAMI arcade game Road Fighter, written entirely in x86 Assembly for the Intel 8088 processor. Features scrolling road, collision detection, scoring, obstacles, and victory/game-over screens.
