Setup an Engineering Organization

Are you starting a tech startup, but didn't find your CTO yet? Or are you a CTO that needs somebody to help them through the early days of the company?

I can help you:

  • Setup core engineering and product management processes (Shape Up, OKRs, Agile)
  • Architect your MVP / PoC
  • Help you select a perfect tech stack for your business
  • Help you design your engineering hiring process / mentor your hiring managers
  • Setup monitoring of core KPIs and engineering metrics.

Artificial Intelligence and Machine Learning

Machine Learning is not magic - I can help you utilize it to automate work, make smarter products, predict business KPIs, and more.

I have extensive practical experience with both building models from scratch and fine-tuning pretrained models. Combined with my expertise in building data systems from scratch, I can help you develop an end-to-end production solutions.

Some of the use cases I can help you with:

  • Predictive analytics and forecasting
  • Image classification and segmentation
  • Natural language queries, sentiment analysis, conversational AI
  • Generative AI, anomaly detection, recommender systems, etc.

Data Processing & Analytics

Running blind is scarcely a good idea. Yet, building and maintaining a resilient data system is one of the hardest engineering tasks there is.

I have extensive hands-on experience in data engineering, analysis, visualization, and science, coupled with a proven leadership track record.

Some examples:

  • I led data engineering & analytics team and a BI team as a head of data at a medium-sized company. We have dramatically improved data quality, system stability, and regularly uncovered new insights. I established unified data glossary and metrics across the organization.
  • I built a highly resilient, low latency system for natural language search, data aggregation, and data visualization for one of the leading ML-powered BI-startups.
  • Together with the CTO, I designed and built a PoC of a data system for an e-commerce aggregator startup, delivering first dashboards and data pipelines in just two weeks.

DevOps, DevEx, Infrastructure, and Cloud Management

Dev process & infrastructure automation can help you accelerate feature development, improve uptime, and limit costs.

I'll help your team design and implement a modern CI/CD automation, no-downtime deployments, provisioning, monitoring, and more.

I can build a system of isolated production-like development environments to streamline business/engineering collaboration and testing.

And, if your cloud bills are biting, I'll help you optimize the cloud costs.

Design & Build a Proof of Concept/MVP

When you start a new business or want to try out a new direction at the existing company, speed is of the essence. Yet, you don't want to be stuck with a PoC that you cannot develop into a real product if it verifies your hypothesis.

Using my extensive engineering experience, I can design and build a maintainable PoC for you in a short time.

I speciallize in web development, high load/distributed systems, and data systems. This is combined with my infrastructure & product management skills, so you'll get software that is easy to deploy and that keeps track of metrics that matter.

Over the years, I've designed over a dozen systems and worked for some big IT companies , medium sized companies , and various   startups in both leadership and individual contributor roles.

You don't need to trust my words to verify my skills: just check out my YouTube channel or look at my Github profile .

Technologies I Use

Here you can find the table of technologies I have experience with.
For greenfield projects, I'll help you select a set of technologies most suited to your business needs.

You'll notice that tech-wise I have extensive experience with infrastructure, functional programming, distributed and web applications, data analytics, science, and engineering.

I'm full stack, though usually my focus is on backend / infrastructure level work, even though I have extensive experience with JavaScript and various frontend frameworks.

I'm cool with both Kubernetes and old-school deployment setups with Ansible or Bash. I work on Linux and macOS.

How I Work

So, how do we start? Depending on the project, I follow slightly different processes during the implementation/delivery phase, but in any case we'll first have a short conversation to figure out if I can be of help to you and if the project fits my schedule.

Press "Hire Me" and fill the short form on this website


Contact me on Malt / Upwork
I'll respond with a Calendly link in 1-2 workdays
We discuss the project outline, availability, cost, etc. on a 15 minutes video call
I work on your project and deliver results

Below you can select a project type and see how the process will look like in each case. Some projects (e.g., executive consulting) may deviate from this outline depending on the task at hand.
