Skills
Backend developer with IoT, database and system administration experience
Some of my recent projects include:
• gorgias.com: Architecture and implementation of a high performance growth stack backend integrating multiple sources of data. Used AWS Lambda, Step functions, API Gateway, SQS with DLQ, S3. Handled ~3.8M domains in Hubspot, data sources like BuiltWith, ZoomInfo, Kickstarter, Storeleads, PredictLeads, and many more.
• technostrobe.com: monitoring solution for obstruction lights: SNMP and MQTT communication with devices, Python Flask back end, Vue frontend, MySQL as database
• threatinformer.com: Architecture and back end for cyber security insurance intelligence: multi layer AWS Lambda orchestration with multi region deployment, PostgreSQL for persistence layer.
• Project to give economic stock alerts like RSI, MACD, STOCH, STOCHRSI, ATR, Highs/Lows, Ultimate Oscillator, ROC, Bull/Bear Power, and others. We are using the backend AWS platform based on different Lambda script, more DynamoDB tables, EventBridge, API Gateway. Send alert by SMS SNS or SES Email. JS website and user authentication to show the evolution of stocks and alerts.
• IoT solution for unified HVAC automation. Using Raspberry Pi, LAMP & Python technologies. Developed the frontend (on a touch screen) and backend to integrate with sensors and control the temperature of the air
• C application on Arduino microcontroller for access control using bluetooth
Preferred technology areas:
• Python 3, C, PHP
• Vue.js, Flask, Docker
• AWS: API Gateway, Lambda, Step Functions, IoT, EC2, DynamoDB, RDS, S3, SQS, SNS, Kinesis, SES
• PostgreSQL, MySql, Redis
• Raspberry Pi, SBC, Arduino
Let's have a short call to talk about your project and how I could help you.
