Sasha Chedygov's CV

Who Am I?

I am a full-stack software engineering leader with a track record of delivering robust, reliable products with great user experiences. I've been writing code for over 20 years and doing it full-time for 13. Most of my experience is with web technologies, but I take pride in being well-rounded and an extremely quick learner.

Work Experience

Founder @ Semi-Decent November 2024 – Present

  • Svelte
  • TypeScript
  • Python
  • Django
  • PostgreSQL
  • AWS
  • Terraform

Together with Ben Goertz, I founded a software consultancy called Semi-Decent where you pay for results, not hours. We deliver finished solutions within 6 weeks with a money back guarantee.

No delays. No scope creep. Just functional software.

  • We work in up to 6 week blocks and guarantee a deliverable at the end of each block. If you need us for a larger project, you can book multiple blocks, but we plan each block as if it were a completely separate project with its own deliverable.

  • We offer a 100% money back guarantee. If you aren't satisfied with our work at the end of a block, you can get all of your money back for that block and you never have to see us again.

  • We have none of the overhead of a traditional engineering organization. Once we've finalized requirements for a project, we put our heads down and get to work. This means we iterate more quickly and get vastly more work done than the average dev team.

I led a team of frontend engineers in building a web and mobile platform for remote health studies. I served as an engineering manager for a year. My duties and accomplishments included:

  • Spearheaded an initiative to improve reliability for a product serving millions of study participants by migrating to TypeScript, adding robust monitoring, vastly increasing test coverage, and removing redundant sources of truth, ultimately decreasing error rates by more than 75%
  • Built a new study platform using a cross-platform content rendering engine powered by a server-driven architecture that allows changes in logic to be made on the backend without needing updates to frontend apps
  • Mentored and led a team of frontend engineers while coordinating larger efforts across teams
  • Set quality standards for our products and codebases to ensure long-term health and adherence to accessibility standards such as WCAG 2.2

  • React
  • Python
  • Django
  • Node.js
  • PostgreSQL

Manzama's products provided market intelligence services targeted at law firms. Notable accomplishments include:

  • Built the frontend and parts of the backend API for a data analytics product condensing 30+ terabytes of global news data into actionable insights, which was a key factor in Diligents's acquisition of Manzama
  • Upgraded the frontend development stack across the company to utilize modern React (from YUI and jQuery)
  • Enhanced error logging and monitoring across the company to cut error rates and downtime by more than 50%
  • Introduced GraphQL to the backend via a homegrown library to consolidate our ad hoc REST-style APIs
  • Taught modern frontend development practices to the engineering team in the form of internal seminars

  • Python
  • Django
  • PostgreSQL
  • Machine learning
  • Frontend JavaScript
  • React

I created a software platform for non-profit organizations that predicted the likelihood and capacity of donations from their prospective donors. The core of the platform was a prediction algorithm that combined machine learning with donor heuristics to produce a set of actionable reports for clients. These reports were accessible via an interactive Django-powered web app. I briefly became a business partner before DonorDynamics was acquired and dissolved.

Software Engineer (Contract) @ Readiness Systems May 2013 – September 2014

  • Python
  • Flask
  • PostgreSQL

I developed a web app that tracks AED readiness and related certifications in accordance with local health and safety laws. It was sold to another company in November 2015, and I provided maintenance services for the software until 2023.
