Senior Python Engineer

Sila

Joined the backend team at Sila and helped with their new initiatives that were focused on improving organization productivity.

Together with the finance team, we were able to automate the billing process and reduce the 15+ hours a month the finance team had to spend manually generating the invoices for customers.

This process involved several integrations(Google Sheets, AWS S3, Quickbooks) and more.

Software Development Consultant

Nagish

Worked with the Nagish team to help migrate from a GQL API to a Rest API using the OpenAPI V3 standard, using the OpenAPI V3 spec opened many doors.

• The API behavior and accuracy were now accurate
• Serverside stubs could be generated
• A client SDK could be developed from the spec.

By moving to OpenAPI V3, it became a lot easier to build the backend and integrate the front end.

Rock It

Helped a non-technical Founder design, build, test, and launch an MVP mobile application in 3 months.

When I was asked to join the project, development was significantly behind due to the existing team in place not delivering and dragging their feet on the work.

I reviewed Github with the Founder and we determined based on the commit history that several team members were billing full work weeks but not committing code to the repository.

We were able to cut ties with unproductive team members, increase the marketing budget, and hire productive engineers that allowed us to make up for lost time,

The mobile app launch was successful and 2,000 users signed up in a span of several hours, we continued to add new integrations and features based on user feedback.

Senior Software Engineer

Lead of Enterprise Legacy Integration & Onbording, using both Python and Go I was able to put in place new architecture in AWS using Lambda, Kinesis, API Gateway which reduced the time to onboard enterprise customers from our legacy POS(IRIS/EDM) to our new POS(Xenial) by 2 orders of magnitude. The architecture was using a Python OOP approach which supported custom configuration for each customer and allowed for a robust and rapid development.

Created a Delete and Archive strategy which after every ETL processes deleted the old data and archived it to s3 in a Mongo importable format(BSON) which allowed us to revert data back to previous states quickly.

2ULaundry

Wrote both the front facing website and the internal website used by our different departments(Customer Service, Marketing, Finance, etc..). Managed our servers on Digital Ocean as well as harden the server with Fail2Ban and whitelisting IP’s.

The website is a traditional server rendered app powered by Django and Python. Our stack consisted of Django, PostgreSQL, Gunicorn, Nginx, Linux, Redis and Celery as our distributed task queue. 

Integration with many 3rd party services, Writing custom templates for email campaigns & batch sending them via SendGrid. Writing the cron jobs to send texts to customers who have a pickup scheduled the next day. I also wrote hooks that tied into OnFleet so we could create a pickup manifest for all the successful pickups everyday.

Some of the 3rd party services we used:
• Twilio (Text messages)
• SendGrid(Emails)
• SurveyMonkey(Surveys)
• ZenDesk(Customer Support)
• OnFleet(Logistics Management)
• Google Places API(Location)

Software Engineer

Label Interactive

As part of a small team I played a really important role in the development life cycle. My responsibility was mainly on front end development using HTML, CSS, JavaScript(Vue.js, Angular). 

Projects were small to mid sized(1-15 pages) and timelines were tight so as soon as I received the final requirements and PSD's for a project I got right to building the front end because there wasn't any additional time to for anything else.

Each project requirement was significantly different and ranged in complexity both in terms of design and functionality which taught me a lot and allowed me to be put in many different situations where I had to learn how to overcome not knowing how to implement the solution in HTML/CSS or JavaScript.
