Senior Elixir / Phoenix LiveView Engineer
I make my living as a software developer with experience in Elixir, Ruby,
PHP, and JavaScript. I've worked across different stacks, mostly building
backend systems and APIs, but I’m comfortable doing full-stack work when
needed.
I’ve contributed to projects in marketplaces, real estate, healthcare,
Web3, finance, and e-commerce. Most recently, I’ve been focused on Elixir
and Phoenix LiveView, and I really enjoy the simplicity and clarity the
language brings. I’ve also worked with Docker, PostgreSQL, and various
frontend frameworks like Svelte and AlpineJS.
I’ve made mistakes, missed deadlines, and learned a lot from them.
I take responsibility and try to get better with every project.
PS: I am a theoretical physicist. I deliberately abandoned my PhD and left
academia as an act of protest.

SUMMARY
------------------------------------------
Backend-leaning product engineer with around 17 years building production
software for startups, remote teams, and consulting clients. I mostly work
with Elixir/Phoenix LiveView and PostgreSQL, with a background in Ruby,
JavaScript, iOS, Docker, and AWS.
My work is usually about taking real business workflows, turning them into
maintainable software, improving existing codebases, reviewing pull
requests, helping other developers, and shipping useful software in small
distributed teams.
CORE STRENGTHS
------------------------------------------
- Elixir / Phoenix LiveView: internal tools, marketplaces, product
workflows, and backend-heavy web applications.
- Backend product systems: business logic, workflow modeling, APIs,
persistence, background jobs, and integrations.
- Ruby on Rails maintenance: legacy code, feature delivery, bug fixing,
performance review, and Rails APIs.
- Technical leadership: pull request review, mentoring, developer
onboarding, technical consulting, and code quality improvement.
- Remote delivery: distributed startup teams, stakeholder communication,
product iteration, and independent execution.

HOW I WORK
------------------------------------------
I work best in small teams where the codebase, product needs, and business
reality are close together. I am not a loud management type. I prefer direct
communication, clear ownership, honest tradeoffs, code that is easy to read,
and steady delivery.
I question things when they do not make sense. That does not mean I want
conflict. It means I want the team to avoid habits, rewrites, vague tickets,
and technical decisions that create more problems than they solve.
I usually help by making unclear work clearer: what the problem is, what
matters, what can wait, who owns the next step, and what a good enough
result looks like. I care about maintainability, but I also care about
shipping. The useful answer is usually the one that respects both.
LEADERSHIP STYLE
------------------------------------------
I lead through clarity, responsibility, and useful feedback. I do not need
to be the loudest person in the room. I am comfortable reviewing code,
mentoring developers, documenting decisions, explaining tradeoffs, and
protecting the team from unnecessary noise.
BEST-FIT WORK
------------------------------------------
I fit well in teams working on legacy systems, internal tools, backend-heavy
products, LiveView applications, Rails-to-Elixir modernization, and
AI-assisted codebase improvement. I prefer careful upgrades over rewrites
unless a rewrite has a clear business reason.
WORKING PRINCIPLE
------------------------------------------
Be clear. Be useful. Tell the truth. Keep the code understandable. Do not
make the work more dramatic than it needs to be.
