Join a company where smart people solve hard problems together, and enjoy the ride.
MEET MY TEAM
When I take on an engagement as a fractional CTO, I can bring engineers with me who can build what we decide on.
Gaofeng Wang
Gaofeng operates at the strategic layer of product delivery: roadmap sequencing, stakeholder alignment, and the decision of what gets built versus what gets deferred. He has been the PM on projects where scope had drifted significantly from the original objective, and the job was as much about stopping work as directing it.
Saif Wang
Saif works at the boundary between what the business needs and what the engineering team can deliver. He has held the Product Owner role in Salesforce implementations, custom SaaS builds, and enterprise platform projects — managing backlogs, writing acceptance criteria, and being the person engineers can actually get a decision from before the sprint ends.
Shuwen Wang
Shuwen has eight years of experience shipping backend systems across fintech, logistics, and enterprise SaaS. Brought in when architectural decisions have been deferred too long and the technical debt is starting to determine the roadmap, she builds things that hold up — and documents them so they don't walk out the door when the engagement ends.
Lei Chen
Lei Chen is embedded in teams that are working but not delivering predictably. He sets up and runs the ceremonies — standups, sprint planning, retrospectives, backlog refinement — until the team has the muscle memory to run them independently. He's reduced sprint velocity variance from over 40% to under 15% across multiple engagements by fixing the delivery structure, not the people.
Hongxiao Zhang
Hongxiao works on the infrastructure and security layer that most projects underinvest in until something goes wrong. He's been embedded in teams where cloud architecture was set up fast and never properly revisited, and where security controls came too late in the build. He designs and implements infrastructure built to scale and secured from the ground up.
Vince Ge
Vince has experience running delivery for teams that span in-house developers, offshore contractors, and client stakeholders simultaneously — the model where communication overhead is the primary cause of delay. He knows which ceremonies to run, which to cut, and how to create a delivery rhythm that holds under the pressure of real client deadlines.
Zhixiang Gao
Zhixiang builds the test coverage that projects skipped on the way to launch and are now paying for in production incidents. He's been embedded in projects mid-build to establish automated test suites, define acceptance criteria, and create the quality baseline that lets the team ship with confidence rather than hope.
Mingfei Xia
Mingfei specialises in the point where a project is nearly complete but nobody can determine what "done" actually looks like. He brings a structured approach to acceptance testing, regression coverage, and release readiness that gives both engineers and product stakeholders a single honest answer about whether the software is ready to ship.
Yunfeng Song
Yunfeng builds and operates the infrastructure layer that determines whether a product runs reliably in production or becomes a source of incidents. He has migrated legacy on-premise systems to cloud, established monitoring and alerting where there was none, and structured deployments so that shipping a release is a routine event rather than an all-hands exercise.
Le Li
Le embeds in projects where testing has been an afterthought and where that's now showing up as bugs in production and releases that slip. He builds the test coverage and processes that should have been there from the start, working closely enough with developers that quality becomes part of how the team builds day to day.
Zhicheng Fu
Zhicheng builds backend systems that need to work reliably at scale, in production, under real load. He's been brought into projects where the architecture made sense early on but couldn't carry the weight of what the product became. He knows where the structural problems usually hide and how to fix them without pulling everything apart.
