Senior Backend Engineer with 10 years of experience building high-scale data systems. Most recently spent 6 years at Toggl on the Reports/Data Visualization team, where I led the design of an ETL pipeline serving 2 billion time entries (timeout → sub-3s worst-case), built a DSL-based report engine serving 3 products, and delivered a historical billable rates system across 4 hierarchy levels as a 6-month solo project.
I also run a side business with a video surveillance platform (84+ cameras, bare-metal infrastructure) and a legal document automation tool that reduced prep time by 78%.
Looking for remote Senior/Staff Backend roles at product companies. Strong in query optimization, system design, and turning ambiguous requirements into working software.
Remote: Yes
Willing to relocate: No
Technologies: Go, PostgreSQL, Python, Django, Redis, Docker, ETL pipelines
