We are a small, focused team of engineers, product thinkers, and operators united by a shared belief: that developer tools should be as good as the code developers write with them.
Alex spent seven years as a software engineer at Google, working on developer productivity tooling that scaled to tens of thousands of engineers across the organization. His work ranged from code review infrastructure to internal data comparison systems used by SREs and data engineers worldwide. Frustrated by the fragmented landscape of data comparison tools available to everyone outside of large tech companies, he left Google in 2023 to co-found DiffChecker Pro with a clear mission: build one tool that handles every comparison scenario a developer will ever face. Alex holds a BS in Computer Science from Stanford University, where he specialized in distributed systems and human-computer interaction.
Maria was a principal engineer at GitHub, where she led the team responsible for the code review and diff infrastructure that powers the comparison view seen across 100 million repositories. Her work there gave her deep expertise in large-scale diff algorithms, merge conflict resolution, and real-time collaborative editing at massive scale. She joined Alex as co-founder after recognizing that the same pain points she solved internally at GitHub existed for every developer who lacked access to enterprise-grade tooling. At DiffChecker Pro, Maria oversees the entire technical direction, from algorithm design to AI integration. She holds an MS in Computer Science from MIT and is a regular speaker at systems engineering conferences in the US and Europe.
David shaped core product experiences at Figma across five years, including the design system and collaborative editing features now used by design teams at tens of thousands of companies. He built his product instincts in an environment where every interaction is scrutinized by the world's best designers, which gave him an unusual eye for reducing friction in complex workflows. He joined DiffChecker Pro because he saw an opportunity to apply the same obsessive attention to UX to developer tools — an area traditionally underserved by good design. At DiffChecker Pro, David owns the product roadmap, user research, and the end-to-end experience from onboarding to daily use. He is passionate about building interfaces that feel invisible and workflows that feel inevitable.
Sarah led platform engineering at Stripe for four years, building and operating the infrastructure that processes billions of dollars in annual payment volume. Her work there included zero-downtime database migrations, real-time event processing pipelines, and the internal developer platform used by hundreds of Stripe engineers. She joined DiffChecker Pro to help build the kind of engineering culture she had always wanted to be part of — one where reliability is non-negotiable, deployments are fearless, and every engineer owns their systems end to end. At DiffChecker Pro, Sarah manages backend engineering, infrastructure, and the on-call rotation. She is a strong advocate for blameless incident reviews, exhaustive runbooks, and writing less code by reusing more.
James brings eight years of backend engineering experience from companies including Monzo and Deliveroo, where he worked on high-throughput payment and logistics APIs. At DiffChecker Pro, he owns the Laravel API layer, database migrations, and the Python microservice bridge that handles heavy format conversions like Excel, PDF, and Parquet. He is meticulous about API design, obsessive about query performance, and the person most likely to catch a missing index in a code review. James is also an active open-source contributor and maintains several PHP and Python libraries used by thousands of developers.
Priya has a background in natural language processing and machine learning, with a PhD in computational linguistics from the University of Toronto. Before joining DiffChecker Pro, she worked at a Series B AI startup building document understanding pipelines using large language models. At DiffChecker Pro, she owns the entire AI layer — prompt engineering for the Claude-powered diff summary feature, the caching layer that keeps AI costs predictable, format detection heuristics, and the guardrails that prevent unexpected model behavior. She is particularly interested in making AI output explainable and auditable, not just impressive.
Marcus has spent six years building and operating cloud infrastructure for SaaS products, with deep expertise in AWS, Redis, MySQL at scale, and container orchestration. He is the reason DiffChecker Pro maintains its 99.9% uptime SLA. At DiffChecker Pro, he owns infrastructure provisioning, CI/CD pipelines, monitoring dashboards, incident response, and the Redis caching layer that keeps response times fast even under heavy load. Marcus is also the team's security champion, responsible for penetration test follow-ups, dependency audits, and secrets management. Outside of work, he contributes to open-source infrastructure tooling and teaches DevOps workshops online.
Emma is the voice of DiffChecker Pro's users inside the company. She came from a customer success background at a developer tools SaaS company serving over 50,000 engineers, where she learned that the best way to retain users is to make them feel genuinely heard. At DiffChecker Pro, Emma manages all user-facing support, maintains the help documentation, runs quarterly user interviews, and translates user feedback into actionable product insights for David and the engineering team. She is also responsible for onboarding new Pro and Team customers, ensuring they get value from the platform quickly. Emma is the first person in the company to notice when something is not working — often before any monitoring alert fires.
We are always looking for exceptional people who care about developer experience, write clean code, and want to build tools they would use themselves. We offer competitive salaries, equity, full remote flexibility, and a team that respects your time and expertise.
